I See the Moon!

It’s a big week for moon-lovers. Tuesday July 16th marked the 50th anniversary of the thrilling Florida blast-off of the Apollo 11 spacecraft on the three-stage Saturn V rocket, propelling the three astronauts, Michael Collins, Neil Armstrong and Buzz Aldrin into space.  The astronauts sat in the Columbia command module. Attached to Columbia were a service module and the Lunar Module Eagle tucked away inside.   The Lunar Module had two parts, a descent module with rockets for landing gently on the moon and an ascent module with its own rockets for returning to Columbia.

With the third stage of the Saturn rocket still attached, Apollo reached its orbital path just over 100 miles above earth.  Then Saturn fired again, pointing  Apollo on its route towards the moon in a move called the “translunar injection”.  Finally, the Command and Service Modules detached from the protective compartment carrying the Lunar Module, flipped 180 degrees in space, and extracted the Lunar Module. At the same time, they jettisoned the third stage of Saturn V.  Only 3-1/2 hours had passed since blast-off. Incidentally, you can follow these complex steps on a great video here.

For three days, Apollo 11 flew through space, reaching the moon’s orbit on July 19th, 1969. While pilot Michael Collins remained in Columbia, Armstrong and Aldrin transferred into Eagle and descended slowly to the lunar suface on July 20th.  This part was broadcast live throughout the world. Does anyone of a certain age not remember where exactly they sat in front of a television beaming audio of Neil Armstrong and his “giant step for mankind”, then watching Buzz Aldrin clomping around in his bulky space suit?  I was in my family’s living room in North Delta, a Vancouver B.C. suburb, along with various friends and neighbours.  Even our parish priest was there.  It was the most thrilling thing we’d ever seen.  Armstrong and Aldrin would stay on the moon for more than 20 hours.

Forty years later, as I related in a recent blog, I would spend a few years working with the music of the late California singer-songwriter John Stewart (1939-2008) to develop a theatrical treatment of his songs.  The former Kingston Trio member was a huge space fan, had become friends with John Glenn and Scott Carpenter during the Mercury 7 flights of the early 60s, and was watching the Apollo 11 landing with a song he’d composed all ready to be recorded. Later that week, ‘Armstrong’ was pressed as a single and sent out to radio stations everywhere.  Though it met with disapproval from some station execs who wanted only to focus on the glory of the moon shot, John Stewart’s lyrics captured beautifully the universal awe that attended the landing. This is the video I made featuring his song.

I love photographing the moon. Winter, spring, summer, fall, eclipses …. I like nothing better than to point my lens skyward and feel connected to that silvery orb.  So here are some of my images from the past eight years, with some fun facts about our only natural satellite.  I’ll start with the only photo I made using our Schmidt-Cassegrain telescope and an adaptor ring to attach my camera, on April 6, 2012.  So close is the moon to earth – 384,402 km (238,856 mi) that I was unable to fit the whole moon into the photo.   In terms of space-time, the moon is 1.3 light seconds from earth, compared with 8.3 light minutes from the sun.

Without a telescope, my little zoom lens camera manages to capture some of the moon’s topography, though not as clearly.    This was a full moon on August 7, 2017.  To photograph the moon, it’s a good idea to use a tripod, but my 50x fixed lens on my little old Canon SX50HS does manage pretty well.

How big is the moon compared to other planets in our solar system? Here is the list according to size of planets and moons in our Solar Galaxy, beginning with the biggest celestial body, our star, the sun.    SUN-Jupiter-Saturn-Uranus-Neptune-EARTH-Venus-Mars-Ganymede-Titan-Mercury-Callisto-Io-MOON-Europa-Triton-Pluto.  The sun’s radius is 696,342 km radius, earth is 6,371km, the moon is 1,731km.  Put another way in another dimension for another country, the sun’s diameter is 864,400 miles, earth’s is  7,917.5 miles, the moon is 2,160 miles.  So the sun is 400 times as big and as distant as the moon, and earth is 3.7 times as big as our moon.

Why do we see only one face of the moon… i.e. “the man in the moon” or the “near side of the moon” (unlike the Apollo astronauts, who landed on the dark side)? My son tried to explain this one night by slowly rotating a beer bottle so its label was always facing the same side of another rotating object on our deck. It may have been the wine, but I didn’t really understand then; having read about it, I can now say it’s the result of “synchronous rotation”.   Moon orbit also gives earth its high and low tides. Have a look at this YouTube video, which is an excellent tutorial.

The moon was once part of earth. Earth formed 4.54 billion years ago (or 4.54 thousand million years ago, since billion means different things in different countries).  According to the Giant Impact Hypothesis, the moon is believed to have formed slightly later, 4.51 billion years ago, originating as a debris ring when an astral body the size of Mars, named Theia, which was also orbiting the sun, hit either a glancing blow to young earth (proto-earth) or smashed into it head-on and ejected some of earth into space.  Although some of the debris went into deep space, enough ejecta remained in the vicinity to begin accreting into a sphere that started its orbit of the mother planet, becoming earth’s only permanent natural satellite.  Scientists have found Theia’s signature remains both in earth rocks and in samples of rock collected on the moon.  The little bit of treed earth beneath the September 11, 2011 full “corn moon” below  is a cliff of roughly 1.4 billion-year-old Precambrian Shield that forms the shore of Lake Muskoka, north of Toronto, where we have a cottage (and where I blog about my meadow gardens).  In aboriginal tradition, each of the full moons was named for the season, September being the time to harvest corn.

In ancient times, the moon cast its light onto a world where darkness was the nightly norm.  When I turn out the lights at our cottage and photograph the sky “by the light of the silvery moon”, it’s easy to see the natural advantage moonlight gave to those wanting to travel or work at night.   I made the photo below this week, on the anniversary of Apollo 11’s blastoff.  Sometimes, a partly cloudy sky illuminated by the full moon is even more interesting than a black velvet sky.

The night before, I was transfixed by the reflection of the nearly-full moon in the waves lapping at our shore below. I thought that dreamy vision would be a suitable accompaniment to the most famous song about the moon, Claude Debussy’s 1890 ‘Clair de Lune’, played by Francois-Joel Thiollier.

One moonlit night as I was turning out the lights to head to bed, I noticed our lamp silhouetted on the floor in our perfectly dark cottage. For some reason, this little image struck me and I photographed it. It made me reflect upon shadow and light, natural chiaroscuro, and our over-lit society.

But the light of the moon isn’t always an advantage.  Full darkness is a way to hide troop movements (though D-Day apparently, needed a full moon for tidal reasons, not illumination) and criminal activity. When we were in Osoyoos, B.C. last September doing a little wine-tasting, we liked the vintages of Mooncurser Vineyards, below.  “Osoyoos, the border town where our winery is located, has long been celebrated for the rich soil and brilliant sunshine. But during the gold rush, it was the dark of night that brought commotion to the area. Then, an unscrupulous procession of gold-smuggling miners returned stateside by the hundreds, if not by the thousands. All under the cover of night – trying to avoid customs agents at all cost. Often, the light of the moon would foil their plans, shedding light onto their surreptitious travels and activities. Need we say more about our name?”

But what about moonshine?  Turns out that’s a derivative of “moonrakers”.  And who were they? From Wikipedia:  “This name refers to a folk story set in the time when smuggling was a significant industry in rural England, with Wiltshire lying on the smugglers’ secret routes between the south coast and customers in the centre of the country. The story goes that some local people had hidden contraband barrels of French brandy from customs officers in a village pond. While trying to retrieve it at night, they were caught by the revenue men, but explained themselves by pointing to the moon’s reflection and saying they were trying to rake in a round cheese. The revenue men, thinking they were simple yokels, laughed at them and went on their way. But, as the story goes, it was the moonrakers who had the last laugh.”

I have often walked by the light of the moon. In fact, on March 6, 2012, I made the photo below during a year when – out of a conviction that I need more physical activity than getting up from my computer afforded – I pledged to walk a mile per day and post on Facebook a photo made during my walk, accompanied by a little verse. I called the poems my “walking rhymes”. The rather boring photo below was made late at night on my street.  Incidentally, in aboriginal tradition, that early March full moon would be a “sap moon”.

Another night, another moon
I really should try sleeping soon…
This sphere could be made of Ivory soap
I wish I had my telescope!

What’s a “blue moon”?  It’s reserved for those calendar months that see two moons, since the lunar month is 29.5 days. So blue moons will always be at the very end of the month.  I love this song by Nanci Griffith, recorded many decades ago.  Listen to ‘Once in a Very Blue Moon’.

This was my view from the cottage path on May 20, 2016. In aboriginal tradition, it’s called the planting moon or the milk moon. Here on Lake Muskoka, I call it the new oak leaf moon, the young pine cone moon.

In fact, I find it more interesting to give context to my moon photography, which means I usually frame it with the flora that grows here on our rocky granite shore.  This was the moon shining down on the top of a towering white pine on August 1, 2015.

On October 4, 2017, I found pine needles to feature in front of the moon.

Sometimes, I draw back and photograph the moon shining on our entire little east-facing bay on Lake Muskoka. In fact, the lake is so big (120 km2 or 46 sq mi) that this is just a small part of the section of the area described on maps as East Bay.  The scene below on June 22, 2013, featured the strawberry moon.

The moon is usually described as having eight phases:  New moon, Waxing Crescent, First Quarter, Waxing Gibbous, Full moon, Waning Gibbous, Third Quarter, and finally Waning Crescent. Did you know that you can find the moon phase for any past date? The photo below was made from our screened porch at the end of a dinner that clearly featured some lovely wine. Knowing the date was September 23, 2017, I looked that up on this website and found it described as a Waxing Crescent.  As for the other stuff on that site, I am a complete non-believer. Science is too interesting and magical in itself to confuse it with superstition!

Once every now and then, the moon puts on a show that draws us out of our houses to find a viewing spot. A lunar eclipse occurs when “when Earth’s shadow blocks the sun’s light, which otherwise reflects off the moon. There are three types — total, partial and penumbral — with the most dramatic being a total lunar eclipse, in which Earth’s shadow completely covers the moon”. (from space.com) Interestingly, in this week celebrating Apollo 11, the moon put on just such a show for many parts of the world, but sadly not North America.  However, this winter I stood in front of my house shivering in temperatures that dipped to -20C to record the phases of the January 21st full lunar eclipse, below.   That last red image is the colour of the moon in earth’s shadow, something the pre-science ancients called a “blood moon”.  In the bible, it is written: “The sun shall be turned into darkness, and the moon into blood, before the great and notable day of the Lord.” – Acts 2:20.

Perhaps the most popular phenomenon to capture the public imagination in the past decade or so has been the “supermoon”.  A so-called supermoon is a full moon that occurs when the moon appears to us at perigee, i.e. when the moon is closest to earth. Not all astronomers are fond of this supercalifragilistic hype. Neil deGrasse Tyson is one of them, and has created a funny video to illustrate his point:

But there’s no question that when a full “supermoon” rises in the east over Lake Muskoka, it is a vision to behold. We went across the bay to my brother-in-law’s cottage on May 5, 2012, just so I could capture the full effect of the supermoon as it rose over the pines on the horizon, seemingly orange because of particles in the earth’s atmosphere.

It was worth it, wasn’t it?

On February 19 this winter, I marched down the street to Toronto’s Sherwood Park at the end of our block at dusk to make sure I didn’t miss the “supersnowmoon”.  I sat alone shivering on a park bench, wondering where 73 degrees (longitude? latitude?) was as I peered at the trees lining the ravine.

Then, there it was, framing the leafless maples and elms.

I loved making this witchy moon photo.

Speaking of witches, let’s have a little etymology.  Month, of course, comes from moon. But where does the word “lunatic” come from?  According to Wikipedia: “The term ‘lunatic’ derives from the Latin word lunaticus, which originally referred mainly to epilepsy and madness, as diseases thought to be caused by the moon…..  By the fourth and fifth centuries, astrologers were commonly using the term to refer to neurological and psychiatric diseases. Philosophers such as Aristotle and Pliny the Elder argued that the full moon induced insane individuals with bipolar disorder by providing light during nights which would otherwise have been dark, and affecting susceptible individuals through the well-known route of sleep deprivation.  Until at least 1700, it was also a common belief that the moon influenced fevers, rheumatism, episodes of epilepsy and other diseases.”   Today, though we joke about bad behavior under a full moon, “lunacy” has rightfully been consigned to the dustbin.

Back to supermoons. My most challenging supermoon photo shoot was on November 14, 2016, when I took the ferry from Toronto’s Harbourfront to Wards Island in Lake Ontario. I thought how wonderful it would be to see the moon rise above the city skyline. I parked myself on the rocky shore with a young Irish girl and together we waited patiently.

Alas, the sky darkened and the moon did not show. Could we have gotten something wrong? The Irish girl took her leave and, shivering in the cold, I waited.

My hands and feet finally felt numb, and I gathered my things together. On the way back to the ferry, I glanced up through the trees and there it was, my moon. We had been looking in the wrong direction. As I pointed my lens up through the lacy foliage, I felt relieved and strangely elated. The moon seemed to be saying, “See, I’ve been up here all the time. You don’t need a super-duper supermoon behind tall skyscrapers; you just need the comfort of me lighting the sky, as I have for almost as long as earth has been around.”

Happy 50th anniversary, Apollo 11.  You brought the moon closer to us moonstruck folks on earth.

Pollen for Honey Bees in a Rainbow of Colours

You hear a lot about flower nectar, when people talk about growing “flowers for bees”, but you don’t hear nearly as much about pollen. And given that pollen, and by extension pollination, is the principal quid pro quo in the evolutionary pact that sees bees trade sex services for food, much more should be written about pollen. It is of vital importance to the bee larvae, for which it is the protein that develops their growth. In one of my classic old books on beekeeping, Plants and Beekeping by F.N. Howles (1945), he writes: “It has been calculated that about ten average bee loads of pollen are necessary to produce one worker bee and that on an average one pound of pollen rears 4,540 bees, which works out at about 44 lb. of pollen for an average colony’s breeding requirements in a season.” Without sufficient pollen, the colony would die off.

Because I spent several years photographing honey bees (Apis mellifera) for a book idea I once had, I got to see a lot of pollen up close and personal, like the golden pollen being patiently collected from Gaillardia ‘Mesa Yellow’, below.

I saw bee faces completely dusted with sticky pollen; I watched them perform aerial dance maneuvers as they packed pollen into their corbiculae, before settling back onto flowers; and I observed them flying back to the hive, legs laden with saddlebags of pollen in all colours of the rainbow, like the white datura pollen below.

It’s pollen colour in all its wonderful variety that I want to celebrate here, from the first blossoms of spring to the last of autumn.

Let’s start with hardy perennials and bulbs. Crocuses have very large pollen grains. I’ve watched honey bees curling their entire bodies into silken crocus chalices, like C. x lutea ‘Golden Yellow’, below.

Siberian squill (Scilla siberica) produces azure-blue pollen.

Little striped squill (Puschkinia scilloides) rewards visitors with beige pollen.

Grape hyacinths (Muscari armeniacum) can often be seen with bees working the flowers as they open from the bottom of the spike up. Pollen is whitish-cream in colour.

Orchards are filled with bees in spring, among them honey bees, thus ensuring that there will be tasty fruit come late summer. This is the hardy ‘Reliance’ peach (Prunus persica) with light-brown pollen.

The Dutch call alpine rockcress (Arabis alpina) “honigschub’ or honey bush and it’s easy to see why. Very early in spring, before most perennials have thought about emerging, arabis is feeding the bees nectar and a sticky light-brown pollen.

Although forget-me-nots are prodigious nectar sources – especially considering the vast quantities of the tiny flowers in spring gardens – their pollen grains are among the smallest measured and from my observations, not very prominent in corbiculae (pollen baskets). But for a bee to insert its tongue into the narrow corolla of a forget-me-not, the net result will be that some pollen will dust off on the proboscis and the head, which the bee will gather for the hive. And because of that narrow opening, pollen is often mixed in with the nectar that forget-me-nots yield, and is measurable in the honey.

Though the shrubby European honeysuckles like Lonicera tatarica, below, can be invasive, they are good early sources of pollen.

The bright-orange pollen of California poppy (Eschscholzia californica) is always a great lure for honey bees.

When the yellowwood tree (Cladrastis kentukea) has a good year for bloom – sometimes just one year in three – the flowers with their tawny-gold pollen are avidly sought out by honey bees and native bumble bees and solitary bees.

Beekeepers always know when Oriental poppies (Papaver orientale) are in flower, because homecoming bees are dusted with black pollen.

Peony stamens are a rich source of pollen, with one count estimating a single peony might have 3.5 million pollen grains.  This is Paeonia ‘Sunday Chimes’, below.

The knotweeds (Centaurea sp.) are excellent plants for bee forage, and beautiful in the late spring-early summer garden.  Globe centaurea (Centaurea macrocephala) offers pollen in golden-yellow…..

….. while Centaurea dealbata ‘John Coutts’ produces creamy-beige pollen.

Southern magnolia (Magnolia grandiflora) is irresistible to bees when the prominent stamens are yielding their creamy-white pollen, below.

Native American copper iris (I. fulva) is popular with hummingbirds, but on the High Line one day, I watched honey bees patiently working the flowers and securing ample loads of near white pollen.

Knautia macedonica is my very favourite pollen producer, yielding a rich magenta-pink pollen that makes honey bee faces look adorable and their packed corbiculae seem like airborne jewelry.

Roses, especially single and semi-double forms with prominent stamens, are often good sources of pollen, which they yield mostly in the morning, apparently. The David Austin shrub below produced amber-brown pollen.

Trigenics is an avant-garde treatment system for nerves and muscles, that provides immediate relief from pain and muscle spasms. buy viagra in stores Back To The Point! like this order generic levitra Ok, so to get back to work. Not to be confused with true roses, Mediterranean rock roses (Cistus species) are also popular with honey bees. The bright-pink hybrid below produced a rich golden-orange pollen.

Certain clematis species are good sources of pollen. One that flowers in early summer is Clematis koreana – and the bee working it had packed a jewel-like pollen pearl in her pollen basket.

Filipendulas are good forage plants and native qneen-of-the-prairie or meadowsweet (Filipendula rubra) provides pollen in early summer for native bees and honey bees. This is the showy cultivar ‘Venusta’ with creamy-white pollen.

Bumble bees and honey bees are always buzzing around globe thistles (Echinops sp.), which yield a whitish pollen from the masses of tiny flowers.

To see a planting of helenium or sneezeweed (Helenium autumnale) in full sun in late summer is to see a happy bee festival. And the abundant pollen is rich orange. One source mentions the bitter nature of helenium honey, but at the point where helenium is in flower, beekeepers are often letting the bees collect nectar for winter honey stores.

Japanese anemones (Anemone x hybrida) yield neglible nectar but the yellow stamens are rich sources of white pollen.

With its masses of tiny, white flowers, sweet autumn clematis (Clematis terniflora) is very popular with bees. I watched the honey bee below doing an intricate aerial dance to pack in white pollen from a massive vine.

By the end of summer into early autumn, the various goldenrods and asters (Michaelmas daisies) offer nectar that is often vital for bees to survive winter, though most beekeepers must provide additional winter food for their bees. (Goldenrod makes a strong honey that is not generally sold commercially.) But bees also collect pollen from these late perennials, like the very late-blooming showy goldenrod (Solidago speciosa), below, with its golden-yellow pollen. This will help sustain the hive until spring.

Of the asters, I loved this image of a bee hanging from lance-leaved aster (Symphyotrichum lanceolatum), its corbicula packed with yellow pollen…..

….. and the beautiful New England aster (Symphyotrichum novae-angliae) and its many cultivars, like the one below, are well worth growing in every garden – something lovely for you and the bees as the season ends.

Annuals and tender perennials and bulbs can also be good sources of colourful pollen. This is Ageratum houstonianum with lots of pure white pollen.

Sunflowers (Helianthus annuus) and their many cultivars are a treat for all types of bees, especially the native sunflower bees adapted to this North American flower. But honey bees enjoy nectaring on the tiny ‘true’ flowers and gathering the yellowish pollen, too.

Single portulacas (P. grandiflora) have bright orange pollen, as you can from the bee crawling out of the silky blossom below.

I’ve seen lots of tender S. African bulbines (B. frutescens) growing in summer gardens recently, much to the delight of honey bees gathering pale yellow pollen from the feathery stamens.

Weeds like Canada thistle (Cirsium arvense) are never appreciated by gardeners, and many are highly invasive and on noxious plant lists. But you will often see bees of all kinds foraging for nectar and pollen on thistles…..

….. and dusting themselves completely with the white pollen of the pretty blue summer flowers of chicory (Cichorium intybus)…..

…. and flying about with the telltale yellow ‘pollen head’ that is a sure sign that the bee has been in a toadflax flower (Linaria vulgaris).

Finally, I’d like to include a few vegetables that bees like – not for the stems or the roots, but for the flowers that have resulted from the plants “bolting”. This is what happens to a radish (Raphanus sativus) when it’s going to seed – yellow pollen much appreciated by this little honey bee.

Brassicas like broccoli, cabbage, kale and Brussels sprouts also form flowers as part of their biennial life cycle – and the bees love the yellow pollen that forms.

Last but not least, a perennial vegetable we all know and love for its tender spring shoots – but have you watched bees gathering bright orange pollen from the tiny, yellow male flowers? It is a feat of acrobatics worthy of any high-flying trapeze act!

(PS  – Are you a bee-lover? To see a large selection of my honey bee stock photography, visit my Smug Mug pages.  And you’ll find a load of bumble bees and other native North American bees and bee kin on my page as well.)

 

 

Piet Oudolf: Meadow Maker – Part Two

Following on part one, this is the second part of my exploration of the Piet Oudolf-designed entry border at the Toronto Botanical Garden.

Planting Plan-Piet Oudolf-Hardscape-Martin Wade-Toronto Botanical Garden

The plant design of the entry walk garden at Toronto Botanical Garden is much more exacting than the drifts and blocks in a conventional border. If you think of a broad meadow like this as a painting, the effect of each series of neighbouring brush strokes is known in advance.  For these plants are like children to Piet Oudolf, many grown and observed for decades in his own Dutch garden, many even bred by him or fellow nurserymen in the Netherlands and Germany.

Piet Oudolf Entry Garden-Toronto Botanical Garden

Designed Combinations

Let’s skip around Piet’s original planting design and have a look at twelve of the combinations he planned, as they manifested themselves over the past decade.  It’s important to note that all these plants fulfill Piet’s mandate that plants must be: relatively adaptable to soil, i.e. neither too wet nor too dry; vigorous enough to grow without fertilizers or pesticides; strong enough to stand without staking (as with the lovely single peonies in Part One, in contrast to floppy double peonies). Plants should be resilient and long-lived. His plant combinations are not dictated by colour, but by form; however, you’ll see some lovely colour pairings in the examples below.

1.Willowleaf bluestar (Amsonia tabernaemontana var. salicifolia) and ‘Purple Smoke’ false indigo (Baptisia australis).

Design-Amsonia & Baptisia-Piet Oudolf design-Toronto Botanical Garden

This is one of the most stable and effective pairings in the entry garden.

Design-Amsonia tabernaemontana var. salicifolia & Baptisia 'Purple Smoke'-Piet Oudolf border-Toronto Botanical Garden

Year after year, these two North American natives (technically, the baptisia selection is called a “nativar”, i.e.  native cultivar) emerge and come into flower at exactly the same time.  They seem to be on the very same wavelength, and equally lovely. And the amsonia, of course, takes on golden-yellow hues in autumn.

Design-Amsonia tabernaemontana var. salicifolia & Baptisia 'Purple Smoke'2-Piet Oudolf border-Toronto Botanical Garden

2. ‘Roma’ masterwort (Astrantia major) and ‘Rose Clair’ geranium (G. x oxonianum).

Astrantia 'Roma' & Geranium x oxonianum 'Rose Clair'-Piet Oudolf design-Toronto Botanical Garden

These two late-spring perennials share a pleasing rosy hue and a soft presence.

3.‘Claret’ masterwort (Astrantia major) & ‘Mainacht’ =’May Night’ meadow sage (Salvia nemorosa).

Design-Astrantia major 'Claret' & Salvia nemorosa 'Mainacht'-Piet Oudolf design-Toronto Botanical Garden

Dark-red ‘Claret’ astrantia is another Piet Oudolf breeding selection, a seedling (like his ‘Roma’ above), of ‘Ruby Wedding’. It looks lovely here in a romantic June combination with indigo-blue ‘Mainacht’ sage. To the left is ornamental clover (Trifolium rubens), to the right is drumstick allium (A. sphaerocephalon).

4. Alaskan burnet (Sanguisorba menziesii) & ‘Amethyst’ meadow sage (Salvia nemorosa).

Design-Salvia nemorosa 'Amethyst' & Sanguisorba menziesii-Piet Oudolf design-Toronto Botanical Garden

I’ll talk a little more about the wonderful burnets in Special Plants below, but this is a good early-summer combination: with zingy, dark-red Alaskan burnet (Sanguisorba menzisii) at rear, violet-mauve Salvia nemorosa ‘Amethyst’ in front, and a lttle spiderwort (Trandescantia) too. If you’re a bee-lover, the meadow sages are fabulous lures.

5. ‘Concord Grape’ spiderwort (Tradescantia x andersoniana) & Knautia macedonica.

Design-Tradescantia 'Concord Grape' & Knautia macedonica-Piet Oudolf-Toronto Botanical Garden

Speaking of bees, both violet-purple spiderwort and dark-red knautia are excellent bee plants, but I do love these jewel-box colours together in early summer. The light-purple cranesbill is Geranium ‘Spinners’.

6. ‘Hummelo’ betony (Stachys officinalis)  & ‘Cassian’ fountain grass (Pennisetum alopecuroides).

Design-Stachys officinalis 'Hummelo' & Pennisetum alopecuroides 'Cassian'-Piet Oudolf design-Toronto Botanical Garden

Here are two of Piet’s German heritage plants growing side by side: Ernst Pagel’s lovely Stachys officinalis ‘Hummelo’ and the fountain grass named for Cassian Schmidt, director of Hermannshof.

7. ‘Walker’s Low’ catmint (Nepeta racemosa) & ‘Cloud Nine’ switch grass (Panicum virgatum)

Design-Nepeta racemosa 'Walker's Low' & Panicum virgatum 'Cloud Nine'-Piet Oudolf design-Toronto Botanical Garden

Catmints are workhorses: long-flowering, great for bees, hardy, with tidy, aromatic foliage.  They do get big in time, but that just means more plants after dividing. Here it is as the switch grass (a warm season grass) is just getting going in early summer. It’s called ‘Cloud Nine’ for its impressive height, to 7 feet (2.1 metre).

8. ‘Gentle Shepherd’ daylily (Hemerocallis) & ‘Purpurlanze’=’Purple Lance’ astilbe (A. chinensis var. tacquetii)

Design-Hemerocallis 'Gentle Shepherd' & Astilbe chinensis var. tacquetii 'Purpurlanze'-Piet Oudolf design-Toronto Botaniical Garden

When the entry walk garden first came into bloom in 2008, I was surprised to see a few daylilies in it. I suppose I thought that with Piet’s focus on the importance of good foliage, daylilies would simply not make the cut, given the tendency of their leaves to go brown and look straggly in late summer. But surprise! There are a few old-fashioned daylilies, including pale-yellow ‘Gentle Shepherd’ which makes a good companion to the fuchsia-pink flowers of spectacular ‘Purpurlanze’ astilbe and is considered a seasonal “filler” plant (see Scatter Plants and Fillers below), with other perennials emerging to carry on the late summer show.

9. ‘Blue Angel’ hosta (Hosta sieboldiana) & ‘Firedance’ mountain fleece (Persicaria amplexicaulis).

Design-Hosta sieboldiana 'Blue Angel' & Persicaria 'Firedance' - Piet Oudolf Design-Toronto Botanical Garden

Yes, Piet Oudolf uses hostas! (Shhh…don’t tell anyone….)  Actually, the big ‘Blue Angel’ hostas here are favourites of Piet’s for their beautiful leaf texture. They act as anchors (there’s one at the other end, too) for this long border. And when they’re flowering, there are always bees buzzing around the white blooms. I like the way the tall white burnet behind echoes the hosta flowers. These hostas also undergo their own foliage transformation, turning gold in autumn. The ‘Firedance’ mountain fleece or bistort (Piet’s introduction) is more compact than ‘Firetail’, and a good, long-flowering perennial.

In writing in Hummelo: A Journey Through a Plantsman’s Life about their collaboration on the 1999 book Designing with Plants, Noel Kingsbury refers to a section of the earlier book called Moods. “We outlined the impact of the more subtle and hard-to-pin-down aspects of planting design, such as the play of light, movement, harmony, control and ‘mysticism’. I am still not 100 percent sure I know what we meant by this category, apart from a lot of mist in the pictures, but it looked good and sounded good.”  For me, the vignette below touches a little on mysticism. There’s something about this combination of forms — the solid echinaceas, the constellation of spent knautia seedheads, the regimental spikes of blazing star, the soft cloud of sea lavender, the blades of grass — that seems almost dream-like. This is my childhood meadow idealized.

Once in a while, you might see a story (usually British) that refers to Piet Oudolf and the other practitioners of the so-called “Dutch Wave” of naturalistic design as focusing entirely on perennials to the exclusion of woody shrubs and trees.  If you don’t know Piet’s work with trees and shrubs (including roses) at The High Line and elsewhere, you won’t see the fallacy in that line of thought. Though the entry garden at the TBG is primarily a perennial meadow, there are shrubs and vines in a few places, including lilac (Syringa), Kousa dogwood (Cornus kousa), witch hazel (Hamamelis x intermedia), chaste-tree (Vitex agnus-castus) and purple-leaved smoke bush (Cotinus coggygria ‘Royal Purple’).  I love the vignette, below, with the burgundy-red foliage and smoky fruit of the smoke bush and the Phlomis tuberosa ‘Amazone’ with the tall alliums (likely ‘Gladiator’) and a sprinkle of white foxglove penstemon (P. digitalis), which is not on Piet’s plan but is now in the border and quite lovely in early summer.

Scatter Plants and Fillers 

In the book Hummelo: A Journey Through a Plantsman’s Life, by Piet Oudolf and Noel Kingsbury (The Monacelli Press, 2015), there are pages devoted to Piet’s use of “scatter plants” and “fillers”.  Scatter plants are defined as “individuals or very small groupings of plants interspersed among blocks of plant varieties or through a matrix planting, breaking up the regularity of the pattern; their distribution is generally quasi-random.”  Scatter plants can act as links in a border, even unifying it, adding contrasting splashes of colour, like the orange-red Helenium autumnale ‘Rubinzwerg’, below…..

Filler-Helenium 'Rubinzwerg'-Piet Oudolf border-Toronto Botanical Garden

…or a pop of colour that later disappears, like the Oriental poppies in the entry garden that later go dormant.

Papaver orientale 'Flamenco'

Fillers are plants whose interest lasts less than three months; though they may have good foliage, they don’t have the structure normally associated with an Oudolf design. They’re good for “filling gaps earlier in the year.” Knautia macedonica does this and cranesbills or perennial geraniums do, too. As Piet Oudolf and Noel Kingsbury wrote in Designing with Plants (Timber Press, 1999), “Think how quickly the neat hemispheres of a hardy geranium turn into a sprawling mass of collapsed stems once the flowers have died.” Yet, when in bloom, they give a starry effect, like the white form of mourning widow cranesbill (Geranium phaeum ‘Album’), below, twinkling among the opening blossoms of Paeonia ‘Bowl of Beauty’.

Filler-Geranium phaeum 'Album' & peonies-Piet Oudolf border-Toronto Botanical Garden

Grasses

If there’s a hallmark group of plants that defines a Piet Oudolf design, it is ornamental grasses. In fact, he and Anja believed so strongly in their value in gardens that they held an annual Grass Days at their garden in Hummelo. And the 1998 book Gardening with Grasses, co-written by Michael King and Piet Oudolf, advanced that respect. Among the grasses featured in the entry garden are:

1.‘Skyracer’ moor grass (Molinia arundinacea), shown here with ‘Gateway’ Joe Pye Weed (Eutrochium maculatum).  This grass is the perfect example of Piet’s use of plants that act as “screens and curtains”. In Designing with Plants, they’re described as “mostly air, and their loose growth creates another perspective as you look through them to the plants growing behind.” This rosy pairing, incidentally, also says ‘mysticism’ to me.

3. Korean feather grass (Calamagrostis brachytricha). Lovely and hardy as it is, its plumes gorgeous in late summer and autumn, this grass did exhibit a tendency to seed around in the entry garden at TBG and had to be watched carefully.

Grasses-Sporobolus heterolepis & Lythrum alatum-Piet Oudolf border-Toronto Botanical Garden

Native North American Plants

Mention of the little-known native winged loosestrife brings me to Piet Oudolf’s use of native North American plants. By the time he was commissioned to do the planting scheme for the TBG’s entry border in 2005-6, Piet had become friends with Wisconsin plantsman Roy Diblik, author of The Know Maintenance Perennial Garden, with whom he worked on Chicago’s Lurie Garden at Millennium Park. As we learn in Hummelo: A Journey Through a Plantsman’s Life, when they visited the Schulenberg Prairie together in 2002,  Roy recalls that Piet “was so taken with it. It was a very emotional moment for him.”  After visiting this prairie and the Markham prairie later that year, Piet began to use many more North American plants in his designs, including some of the less well-known species in my list below.

1.Winged loosestrife (Lythrum alatum) – Mention ‘purple loosestrife’ to ecologically-aware people and alarm bells ring. Try telling them that there IS a native purple(ish) loosestrife and they don’t trust you. Or it could mutate. Or it might really be that other one, the Eurasian invader that’s drying up wetlands everywhere (Lythrum salicaria).  But part of Piet Oudolf’s education with Roy Diblik was the discovery of this sweet plant. Native to moist prairies in Illinois and other parts of the northeast, it is at home in a well-irrigated garden where, rather than taking over like its cousin, it will work hard just to have its little pink flowers noticed.

Lythrum alatum-winged loosestrife

Here’s winged loosestrife with ‘Ice Ballet’ swamp milkweed (Asclepias incarnata). Both species are wetlanders, but do well in regular irrigated soil.

Native wetlanders-Lythrum alatum & Ascelpias incarnata-Piet Oudolf border-Toronto Botanical Garden

2. Swamp milkweed (Asclepias incarnata), shown above, is a larval plant for the monarch butterfly and a fabulous bee plant. The honey bee, shown below with two bumble bees, comes from the TBG’s five beehives and the Oudolf entry garden is a rich nectar source for them.

3. Leadplant (Amorpha canescens) – The soft drift of leadplant in the Oudolf entry garden, below, was my first acquaintance with this lovely tallgrass prairie native,one of a few true Ontario natives in the garden. Its common name refers to the old belief that its presence indicated that there were lead deposits nearby, but that was disproven long ago.  Its other folk names include downy indigobush (because it looks a little like indigofera) and buffalo bellows (because, to the native Oglala people who brewed it for a medicinal tea, it came into bloom when bison were in their bellowing-rutting season). A legume, it nitrifies the soil in which it grows (it’s usually considered a subshrub, rather than a perennial) and is one of the few natives that tolerates both dry soil and part-shade.

Natives-Amorpha canescens-leadplant-Piet Oudolf border-Toronto Botanical Garden

Bees love leadplant and its stamens provide a bright orange pollen. This is the brown-belted bumble bee (Bombus griseocollis).

4. Dense Blazing star (Liatris spicata) – One of the best tallgrass prairie natives for any sunny border, dense blazing star is no stranger to European gardens either, since it’s been available there in the cultivars ‘Kobold’ (shorter and darker purple than the species) and ‘Floristan Violet’ for  decades. Like all Liatris species, it’s a great bee and butterfly plant and a good companion for echinaceas, including Piet Oudolf’s introduction below, ‘Vintage Wine’.

Mention is often made of ‘repetition’ in a Piet Oudolf design and this rhythmic syncopation of blazing stars across the vignette below illustrates how those magenta-purple spikes help carry the eye naturally from one side to the other.

5. Amsonias, Bluestars (Amsonia hubrichtii & Amsonia tabernaemontana var. salicifolia) – When I was writing my newspaper column in the mid-1990s, there was a sudden fuss about a genus of North American plants I’d never heard of. Amsonias were on the scene, and I planted Arkansas bluestar (A. hubrichtii) in my garden, which promptly turned up its toes and died. (It may have been a hardiness issue in an unusually cold winter, since this plant is native to the Ouachita mountains of Arkansas and Oklahoma.) Nevertheless, it gained traction in gardening circles and in 2011 was named the Perennial Plant Association’s Perennial of the Year.  This is how it looks in the Oudolf border with late spring bulbs.

Amsonia hubrichtii-Piet Oudolf Border-Toronto Botanical Garden

Arguably the brilliant yellow of the autumn foliage, below, is even more impressive than its ice-blue late spring flowers. Perhaps with our warmer winters, this species will continue to survive and thrive. 

Natives-Amsonia hubrichtii & Vitex agnus-castus-Piet Oudolf border-Toronto Botanical Garden

There are many species of Amsonia in commerce now, but willowleaf bluestar (Amsonia tabernaemontana var. salicifolia) is a good performer in the TBG entry garden and exceptionally hardy.

6.Joe Pye Weeds (Eutrochium sp., syn. Eupatorium) – The big Joe Pye weeds lend a powerful presence to the entry border in August and September, especially the statuesque ‘Gateway’ (Eutrochium maculatum) below. Given sufficient moisture, they thrive, last a long time in flower……

….. and attract myriad bees and butterflies to their dusty pink flowers.

7. Wild petunia (Ruellia humilis) – Native to dry prairie glades in Wisconsin, Illinois and regions south and west, this short, sprawling perennial has lilac-purple, petunia-like blossoms that are beloved by hummingbirds.  Not showy, but a good little edge-of-path stalwart with a tap root. Self-seeds, too.

8. Anise hyssop (Agastache foeniculum) – One of the mainstays of Piet Oudolf’s designs is this aromatic North American Midwest mint family perennial with bee-friendly, lavender-purple flower spikes in mid-late summer. It spreads slowly by rhizomes.

Natives-Agastache foeniculum-Piet Oudolf border-Toronto Botanical Garden

Agastache foeniculum ‘Blue Fortune’ is an excellent selection with good winter presence.

9. Bowman’s root (Porteranthus trifoliatus, syn. Gillenia trifoliata) – One of the most beautiful pictures in the entry border is right at the end (or beginning, depending which way you’re walking) where the path intersects with the entrance to the Floral Hall Courtyard. Here, in June, a starry cloud of Bowman’s root or Indian physic rises behind a skirt of Japanese hakone grass (Hakonechloa macra).  In its midst is a hybrid witch hazel which, though small now, will in time produce filtered shade under its boughs – and Bowman’s root is just fine in that light.

Special Plants

Sanguisorbas or Burnets – Piet Oudolf, more than any other plant designer, has made abundant use of the great genus Sanguisorba, the burnets.  Hardy, reliable and taking up much less space on the ground than their tall, far-flung inflorescences do in the air, they are a much underused group of perennials.  This is Sanguisorba tenuifolia ‘Alba’, or the white form of Chinese burnet, flowering alongside annual Verbena bonariensis.

Sanguisorba tenuifolia 'Alba'

Like Molinia caerulea ‘Transparent’, Chinese burnet is another good ‘screen’ or ‘scrim’ plant, even as its flowers fade. Here it is in front of Helenium autumnale ‘Fuego’.

Birds & Bees

Speaking of birds and bees, as a photographer of honey bees, bumble bees and various native and non-native bees, I’d be remiss if I didn’t pay tribute to just a few of the great pollinator plants in the Oudolf entry border (besides the ones above, of course).

Calamint (Calamintha nepeta ssp. nepeta) – Calamint is, without doubt, the ‘buzziest’ bee plant there is. The sound is really something, with honey bees and bumble bees all over the tiny flowers – and there are tons of tiny flowers on this bushy little perennial.

‘Walker’s Low’ catmint (Nepeta racemosa) – Long-flowering catmints are superb bee plants, putting out nectar beloved by bumble bees and honey bees.

Bumble bee on Nepeta racemosa 'Walker's Low'

Wlassov’s cranesbill (Geranium wlassovianum) – Previously unknown to me, this little Asian geranium has become one of my favourites. Not only does it flower for an incredibly long time and prefer filtered shade, its flowers are always dancing with bees and its leaves turn red in autumn.

Honey bee on Geranium wlassovianum

‘Robustissima’ Japanese anemone (Anemone tomentosa) – Japanese anemones are invaluable for their late summer-early autumn flowers, especially the singles like this lovely selection. And their stamens provide rich pollen at a time of year when bees are still looking to provision their nests.

Anemone 'Robustissima' and bumble bee

‘Autumn Bride’ alumroot (Heuchera villosa) – It’s fun to watch honey bees working the tiny white flowers of this fabulous late heuchera.

Purple coneflower (Echinacea purpurea) – Echinacea and many of the selections are excellent bumble bee flowers, but they also provide abundant food for seed-eating birds like American goldfinch.  A good reason not to cut down your perennial garden in late summer!

Goldfinch-eating Echinacea seeds-Piet Oudolf border-Toronto Botanical Garden

Seedheads

While we’re on the topic of seedheads, one of the hallmarks of Piet Oudolf’s design philosophy is the use of plants that perform beyond their flowering season, with persistent stems and seedheads that provide structure in the garden into autumn and winter. These are just a few of the entry border’s distinctive seedheads:

Swamp milkweed (Asclepias incarnata) – The familiar chambered pods of milkweeds ripen, dry and split open in late autumn to reveal a layered arrangement of teardrop-shaped seeds topped by fine hairs. Over the next week or two, the seeds will gradually lift off on their silken parachutes, aloft on the wind to land on an empty inch of damp soil on which they’ll germinate the following spring. This is the milkweed life cycle that has evolved over millennia in all its regional species throughout North America in partnership with the monarch butterfly, whose females lay their eggs on the leaves, which then feed the developing caterpillar until it forms its chrysalis to emerge as the familiar orange-and-black butterfly we admire so.

Seedheads-Asclepias-Piet-Ou

‘Purpurlanze’ astilbe (Astilbe chinensis var. tacquetii) – I love the feathery bronze plumes of this Ernst Pagel-bred astilbe with the fountain grass (Pennisetum) behind.

Seedheads-Astilbe

Purple coneflower (Echinacea purpurea) – Long after the American goldfinches (above) have migrated south for the winter and the first snows have fallen, the raised seedheads of echinacea flowers still show their Fibonacci architecture.

‘Fascination’ Culver’s root (Veronicastrum virginicum) – The coppery wands of spent Culver’s root look beautiful against the tawny grasses of late autumn.

Plants That Go, Plants That Come…..

Not all of the original plants in the design thrived beyond a few years. One that was quite short-lived was the beautiful ornamental clover (Trifolium rubens), with dark pink flowers, below.  In an ideal world, this plant would be allowed to self-seed, ensuring progeny for successive seasons. But it has petered out gradually.

Plants-short-lived-Trifolium rubens-Piet Oudolf border-TOronto Botanical Garden

Some of the yellow and orange hybrid echinaceas, like yellow ‘Sunrise’ shown in the early years with purple liatris, below, have also largely given up the ghost. Their lack of longevity (contrasted with the reliable long life of Piet’s Echinacea ‘Vintage Wine’) seems to be part-and-parcel of their genetic makeup, a fact Noel Kingsbury acknowleges in Hummelo: A Journey Through a Plantsman’s Life. “The 2000s saw a lot of breeding of E. purpurea with other Echinacea species, mostly in the U.S…… Some exciting color breaks – oranges and apricots – resulted, but the plants were mostly short-lived. For those wanting longer-lived plants, this breeding has not been of any use. We can only hope that someone picks up Piet’s work on longevity.”

Plants-Short-lived- Echinacea 'Sunrise'-Piet Oudolf borer-Toronto Botanical Garden

Unlike a traditional perennial bed or mixed shrub-perennial border with a modest number of plants, a broad meadow planting like the entry garden with its huge cast of flowery characters is an open invitation to opportunistic plants, good and bad. With so many gardens (including a natural woodland) surrounding the entry walk, it was inevitable that seeds would fly into the rich, irrigated soil – either on the wind, or carried by birds. One of the immigrants – from the green roof of the administration building – is  lovely foxglove penstemon, P. digitalis, a plant whose red-leafed form ‘Husker Red’ is used by Piet in his designs.  Easy, prolific. drought-tolerant and a great bumblebee and hummingbird plant, this penstemon’s shimmering white spikes are quite lovely in June. It’s one of my favourite perennials.

Penstemon digitalis-Piet Oudolf border-Toronto Botanical Garden

But there are also seeds that may have been in the soil for many years, just waiting to germinate. Such is the case with common milkweed (Asclepias syriaca), below, which I first spotted in my photos in 2011, four years after the garden was planted. Like Canada goldenrod, this is an aggressive native that spreads not only by seed, but by rhizomes underground.  Beautiful and fragrant as it is, is difficult to maintain a small population. And given that the better-behaved swamp milkweed (Asclepias incarnata) is here already and there are ‘wild’ places on the TBG property where common milkweed could be welcomed for its relationship to monarch butterflies, I hope it is kept in check so the design intent of the Oudolf garden is not lost.

Asclepias syriaca-common milkweed-Piet Oudolf border-Toronto Botanical Garden

Which brings me to maintenance. Toronto Botanical Garden currently operates on a financial shoestring. Unlike other popular parks and public places in Toronto, the TBG receives a pittance from the city. Hopefully, that will change in the near future as the City of Toronto Parks Department and the TBG conduct public consultations (two so far, one in November 2016, the last in late February) towards greatly increasing the size of the garden from the current 4 acres to 30 acres, placing all the current Edwards Gardens within a civically-supported Toronto Botanical Garden.  However, at the moment, the head gardener works with just a few assistants and a changing team of volunteers to maintain not just the entry garden, but the other 16 gardens on site, and one or two off-site.

Maintenance-Piet Oudolf Border-Volunteers-Toronto Botanical Garden

******************************

For perspective, I chatted with Toronto Landscape architect Martin Wade of Martin Wade Landscape Architects, below right, who collaborated with Piet Oudolf, left, on the design of the entry border, which was gifted to the TBG by the Garden Club of Toronto.

Piet-Oudolf-Martin-Wade

Martin fondly recalled their first meeting.  “It was absolutely wonderful collaborating with Piet.  He is extremely down-to-earth, humble and generous.  I remember so clearly the very first time we met.  After picking him up at the airport, we came back to our house where my partner was preparing dinner.  It was shortly after we had moved in. I had not yet “done” the garden – it was a collection of plants left over from the previous owners. We were in the midst of a renovation and the place was in a bit of a shambles.  IKEA curtains hung to cover exposed plumbing, bare sub-floor in some areas, and yet with all of this, it was somehow as though we had known one another for ages   Piet sat down in a chair that had clearly seen better days and, over a single-malt whisky, the three of us talked about life in general and what our respective interests were. When I asked him what was important to him, he answered, without any hesitation, ‘Quality.  Quality in terms of food, wine, art, relationships, architecture, landscape, virtually everything in life.’  The notion of quality as being the driving force that stimulates him has stuck with me.”

Martin & I talked about maintenance. Unlike Chicago’s 2.5 acre Piet Oudolf-designed Lurie Garden (Landscape Architects: Gustafson Guthrie Nichol), which cost $12.5 million and has a $10 million endowment for maintenance alone, the TBG’s entry garden has no separate budget for maintenance. Similarly, unlike the Oudolf-designed Marjorie G. Rosen Seasonal Walk at the New York Botanical Garden, below, a much smaller garden which has the equivalent of half-a-full-time employee dedicated to maintenance (including the hedge), there is no dedicated employee budgeted for the TBG’s Oudolf garden. 

Marjorie J. Rosen Walk-New York Botanical Garden-Piet Oudolf Design

Before the entry garden was installed, Piet Oudolf, Martin Wade and the Garden Club of Toronto (GCT) had a frank discussion about long-term maintenance of the garden. By Piet’s estimate, the entry border would require a minimum of one full-time gardener dedicated to its upkeep. “As Piet explained,” recalls Martin, “His gardens, while ‘naturalistic’ and ‘meadow-like’ in appearance, are anything but low maintenance.  They require regular tending to keep species that were not part of the original design out. I have noticed the invasion of common milkweed in the garden.  This is a plant that has a host of great qualities and should be encouraged and let flourish in the right locations.  However, it was not part of the original plan.  The intent always was that the garden would be monitored yearly to ensure any of the more aggressive species in the plan were kept in check, and that the original plan be maintained, other than in the case of some species that just might not perform well, for which minor design adjustments would have to be made.  This ‘monitoring’ process involves taking a copy of the plan in hand, walking throughout the garden, making note of what has crept into areas in which it was not meant to, and making adjustments accordingly.” 

Sadly,” he continues, “I don’t think the garden is achieving to the full extent the goals that were envisioned when the project began.  I don’t mean this in any way as a criticism of the TBG or its staff, as I realize the extreme pressure they are under with respect to finances and resources that can be allocated to maintenance, not only of the entry garden, but all of their gardens.  Maintenance is such a huge issue for all gardens, private or public, not only for the TBG gardens.  It is relatively sexy these days to give a new building wing naming rights to honour the benefactor who helped make it a reality.  The same applies to gardens.  While a ‘sexy motive’ was not their intent, the Garden Club of Toronto was nonetheless very generous in gifting the Piet Oudolf/MWLA garden to the TBG.  That is their mandate.  The GCT funds public garden projects.”

Martin cites another of his projects to illustrate the level of financial commitment needed. “Our firm designed the Helen M. Kippax Garden at the Royal Botanical Garden in Hamilton.  The funds for this garden were donated by the late Mary Stedman in honour of her aunt Helen Kippax, one of the founding members of the Canadian Society of Landscape Architects.  Ms. Stedman’s donation is suitably honoured by a plaque in the garden.  She also had the foresight and financial ability to donate money to a trust fund, the interest from which is earmarked solely for the maintenance of the Kippax Garden.  We need these types of visionaries, and institutions need to find a way to raise money not only for the installation of our public gardens, but for their long-term maintenance.

But if the entry garden could use more a little more manpower to relieve the hard-working gardeners and volunteers, it is still, without a doubt, my favourite garden at the TBG. It takes me back to that childhood meadow I’ve carried in my heart for 60 years. It nourishes bees and butterflies and birds and the spirits of the visitors who walk the long path, flanked by a profusion of beautiful blossoms and swishing grasses.

And in case you haven’t taken that walk yourself, let me leave you with a beautiful memory of a warm August afternoon in the entry garden at Toronto Botanical Garden. Thank you, Garden Club of Toronto. Thank you, gardeners. Thank you, Martin Wade. And thank you, Piet Oudolf.

Piet Oudolf: Meadow Maker – Part One

It was early April 1999, and we were visiting Hummelo in the Netherlands so I could talk with Piet Oudolf and see his garden. I had read his books and followed his burgeoning design career with interest.  Given my childhood love of wild places, I was always more interested in designers who embraced a naturalist ethos and synthesized that into their work, whether purely aesthetic or ecology-based. When we visited Hummelo, I had just finished an in-depth magazine profile on Michael Hough, a seminal member of the mid-20th century ecological landscape movement. Scotland-born Michael had been a student of Ian McHarg (Design With Nature) at Edinburgh’s College of Art and later at the University of Pennsylvania, before founding the University of Toronto’s Undergraduate program in Landscape Architecture, then moving to York University to teach in their fledgling Environmental Studies program and publish his own book, Cities and Natural Process.  Later on this trip, we would visit the botanical garden at Leiden and Ecolonia in Alphen aan den Rijn, below, an experimental housing development whose architecture, landscape, utilities and infrastructure had been built earlier that decade using principles of ecological design.

The Oudolfs were generous in greeting us. Anja still ran the nursery then, Kwekerij Oudolf with its goddess Flora…..

….. and retail customers were busy buying the plants that the Oudolfs raised to use in Piet’s designs. In time, other Dutch growers would become adventurous in their plant introductions; this fact, combined with the demands of Piet’s business and Anja’s busy schedule accommodating groups wanting to tour the garden eventually caused the Oudolfs to close the nursery and build a studio in its place.

Hummelo-1999-Piet Oudolf-nursery

We toured the garden; as it was early spring, not much was in bloom, but the hellebores and wild phlox were lovely.

The Stachys byzantina ellipses were still there, along with the famous yew towers and undulating yew hedges which would later be damaged by flooding. Both features were eventually removed and this garden was planted with sweeping perennials.

The trial beds were impressively ordered – and vital in teaching Piet how various perennials performed: their hardiness, floriferousness, optimal companions, seedhead properties, pollinator attraction, winter persistence, etc.

It was still very much a place where the Oudolfs worked as a team to expand and improve the palette of plants, but there were abundant touches of simple domesticity.

Then we said farewell and headed off to the nearby garden of Eugénie van Weede at Huis Bingerden, below.  At the time of our visit, Eugénie been holding her International Specialist Nursery Days, a 3-day June plant fair attracting thousands of visitors, for four years. (In 2016, there were 37 exhibitors.)  In turn, her inspiration came from Piet and Anja Oudolf, who had held their own annual Hummelo Open Days (later Grass Days) beginning in 1983. By the mid-1990s, visitors numbered in the thousands. Wrote Piet in his rich memoir Hummelo: A Journey Through a Plantsman’s Life, by Piet Oudolf and Noel Kingsbury (The Monacelli Press, 2015): “Our idea was to bring people together. Of course we wanted to create some income, but thought it would also be a good idea to bring a selection of growers who share the same interest in plants, as an advertisement for all of us.”   It was Piet Oudolf, seedman Rob Leopold and Piet’s original partner, nurseryman Romke van de Kaa (formerly Christopher Lloyd’s head gardener in the 1970s) — the men she calls her three ‘godfathers’ — who advised Eugénie on the nurseries she should include in her Nursery Days.Eugenie van Weede-1999-Bingerden

Fast-forward 15 years to a lovely day in August 2014, and there I was photographing the Piet Oudolf-designed entry border at my own local Toronto Botanical Garden, as I’ve been doing regularly for more than a decade. Even though I recall my visit to Hummelo with pleasure, my relationship with the entry border feels less like a connection to the Netherlands than an arrow that points right back to my childhood.  A childhood spent in a meadow.

You Can Take the Child Out of the Meadow….

How does one become a meadow maker?  Perhaps it might happen through sheer neglect: abandoning a plot of land to flowering weeds and long grasses which, through a stretch of imagination, might eventually approximate a reasonably attractive community of plants. Though leaving meadow-making to serendipity rarely achieves satisfactory results, it was nevertheless a meadow of happenstance that became my first intimate connection with nature and, by extension, with gardening. For it was an old field across the road from my childhood home in Victoria, B.C., the one just behind the trees at left that you can’t make out in this photo….

Janet Davis-child-Victoria BC

….  that taught me how Spanish bluebells and English daisies emerged in spring as grasses turn green; how California poppies preferred the stony ground to the rich, damp soil where western buttercups grew, the ones we held under our chins to see who liked butter best.

Oxeye daisies and horsetails, bindweed, tansy and purple clover: these were the meadow weeds I came to love. As little as I was, I felt at home in that chaotic wildness, the old field that promised adventure – even the spittle-bugs that brushed our cheeks as we crawled through the grasses on all fours playing hide-and-seek.

If, as landscape designer Julie Moir Messervy contends in her 1995 classic The Inward Garden, the joyful, treasured places of our childhood become the environments we yearn for as adults, my Victoria field was the idyll I tried to recreate a half-century later in the wild front garden of our Toronto home, below, …..

….. and in the meadows of our cottage at Lake Muskoka….

….. where bees and butterflies and birds are welcomed.

But meadow-making, for me, though it became somewhat more ‘designed’ and much more interesting than conventional gardening, never approached an art form. It was more about capturing a little corner of ‘wildness’ outside my door. Making a meadow that appears to be wild but is ‘enhanced nature’, that relies on deep knowledge for its plant palette and a wealth of experiment for its dynamic combinations: that is the work of a master. And that is how Piet Oudolf came to design the entry border at the Toronto Botanical Garden (TBG).

But first, let’s back up a little to 2006.

***************************

Toronto Botanical Garden

In the early 2000’s, when Toronto’s Civic Garden Centre was being transformed from a small, horticulture-related institution to the Toronto Botanical Garden (TBG), a series of 17 themed gardens were designed to skirt around the new LEED building and extend out into the modest 4-acre property. . (You can see my seasonal galleries of all these gardens on the TBG’s website). Landscape architects for some of the gardens included PMA Landscape Architects Ltd. and Sparling Landscape Architects. For the prominent entry walk along the entrance driveway and the long south wall of the building, funding was provided by the Garden Club of Toronto to commission Toronto landscape architect Martin Wade of MWLA, below left, and Piet Oudolf, right, to collaborate on the hardscape and plant design.   Construction-Piet Oudolf & Martin Wade-Toronto Botanical Garden

Garden club member Nancy Laurie (who provided these photographs of the planting) was intimately involved with the beginning of the garden. As she recalls: “The club was asked to design and install a perennial garden that welcomed visitors into a botanical garden. The parameters of the garden area were predetermined by the TBG and the space was limited in height and width variations. It was surrounded by two parking lots, sidewalks and a building.  It would most likely be viewed first by many from inside a moving car. In addition, the other gardens that would eventually make up the new Toronto Botanical Gardens would be of a more formal design. This garden had to stand out from the others. Be different. Announce this is as an avant botanical garden.  Martin Wade proposed including the internationally acclaimed perennial designer Piet Oudolf to join the project as a consultant specifically for the planting design and selection of plants using his much admired naturalistic interpretation of a traditional perennial border garden.”

Apart from having read some of Piet’s books on plant design and hearing him speak at conferences, Nancy had also helped organize several two-day symposiums on the theme of the natural garden. “So I was personally very keen to make this ‘new’ garden paradigm a key element in our new entrance garden,” she recalls. “The garden world of the 1990’s and early 2000’s was embracing a more modern approach to the traditional formal English-style perennial garden. Piet Oudolf’s alternative style is characterized by naturalistic plantings, both in techniques and style, and using plant material that suited the terrain, climate and growing conditions already present in the site. He was recognized at the time as the master of the ‘new perspective of planting’ to paraphrase the title of one of his books. He was ‘The Man’.”

The plant design was complete and ready for reference.

With the hardscaping and rough grading having been done earlier that spring, the garden was ready for planting. But first there were some preliminary steps. The garden was divided into precise grids….

………which would facilitate transference of the design outlines onto the ground.

Once the grid was finished, the outline of the plant groupings themselves was sprayed onto the surface of the soil with a non-toxic paint…..

The Garden Club had teams of planting volunteers ready and they listened to words of wisdom from Piet before starting.  Says Nancy Laurie: “The committee gained enormous experience working through this project. At its completion, I prepared a process paper on how to organize and use volunteers to help install a large garden project under the leadership of a landscape architect. Martin Wade used the suggestions to direct the volunteers at his installation of several new gardens at the Royal Botanical Garden the following year.

Then it was out into the garden. Most of the plants were Heritage Perennials from the Ontario division of Valleybrook Gardens.

As Nancy recalls: “Martin Wade managed the process of planting the garden with the help of Garden Club volunteers. Piet was on site for the first planting day to offer suggestions and help. He conferred with Martin and often stepped into the garden with the volunteers to show them how to properly plant a specific variety.”

Nancy Laurie still recalls Piet’s planting lessons from that day.

  • When ready to plant, start at one end of the garden and move backwards so that the soil does not get compacted with foot traffic. Use planks of wood to walk on especially if the soil is wet so it does not compact.
  • Working in one grid area, dig all of the holes for one plant variety.
  • Loosen the soil around the planting hole several inches larger than the plant root system. Step back and look to see if the planting area is what it looks like on the plan. Adjust if needed before actually installing the plants.

The entry walk was transformed that June into a fluttering, buzzing, verdant place of great beauty, different in all seasons, and indeed different from year to year, as the plants intermingled, possibly even more than their designer intended, and a few disappeared eventually, to be replaced by others. Let’s take a look at a small area, just in front of the glass screen dividing the border from the Floral Hall courtyard just to the north. Here it is on Piet’s plan.

Here’s the area as it looked in early spring 2006, with its new espaliered ‘Donald Wyman’ crabapples and coppery paperbark maples (Acer griseum).

Now look at it in May 2012, below. Seasonal spring bulbs are part of the changing display in the garden and, when carefully planted, they don’t affect the emergence of the perennials in Piet’s design.

Here it is in June 2011 with the Geranium psilostemon and Astrantia ‘Roma’ flowering amidst the lush green foliage of Deschampsia caespitosa.

The genius of the entry garden, for me, especially in the early years when the perennials had not yet seeded about and intermingled, was that it transformed itself through the seasons — especially evident with the ornamental grasses.

Here’s my video of more of the seasonal changes in various parts of the garden.

*********************

Before I move on to more seasonal scenes from the garden, I’d like to acknowledge the hard work of former head gardener Sandra Pella, her assistant gardeners and former TBG horticulturist Paul Zammit, who oversaw the demanding maintenance of the entry garden on a shoestring budget, and with great enthusiasm.

I was there to photograph it each spring….

Families of donors to the garden help to plant new bulbs each autumn, changing the show annually.  The emerging perennials are unaffected by the bulbs growing in their midst.

But the summer months are when the Oudolf garden hits its stride, as the lush, ornamental grasses begin to fountain around the stems of the flowering perennials.  In early summer, deep-red Knautia macedonica pops out like dots in a pointillist painting.

I love knautia for its long flowering season and its attractiveness to all kinds of bees.

Here are three Oudolf favourites:  from rear, mauve ‘Fascination’ Culver’s root (Veronicastrum virginicum), ‘Blue Fortune’ anise hyssop (Agastache foeniculum) and the lime-green, needled leaves of Arkansas bluestar (Amsonia hubrichtii), half-way between its pale-blue spring flowers and brilliant gold fall colour.

A little later comes the beautiful echinacea show, here with the salmon daylily Hemerocallis ‘Pardon Me’ and ‘Veitch’s Blue’ globe thistle (Echinops ritro), which is…..

August is my favourite time in the garden, as the grasses reach their stately heights and the late-season perennials flower.  Here’s a little vignette of what you see as you do the entry walk in early-mid August:  violet spikes of blazing star (Liatris spicata); creamy-white rattlesnake master (Eryngium yuccifolium); the lush, burgundy flowers of the various Joe Pye weeds (Eutrochium sp.); the small, dark-red wands of burnet(Sanguisorba sp.); and echinaceas.

By October, the Virginia creeper (Parthenocissus quinquefolia) on the stone wall of the Raymond Moriyama-designed Flower Hall has turned bright red and the seedheads and fall colour of the big grasses in the Oudolf border take centre stage, along with a few asters and goldenrods that have sneaked into the border from other parts of the botanical garden.

Seasonal 5a-Autumn-Symphyot

One year, aromatic aster Symphyotrichum oblongifolium ‘October Skies’, below, native to the central and eastern United States, looked stunning punctuated with echinacea seedheads.  But this lovely aster, used by Piet at Lurie Garden in Chicago, seems to have diminished in subsequent years, part of the inevitable reality of plant experimentation, something to which Piet Oudolf has paid great attention over the decades.

Perennial seedheads are an important part of the seasonal show in the garden; these are the mocha-brown October seedheads of the yarrow Achillea millefolium ‘Walther Funcke’, with silvery Perovskia atriplicifolia ‘Little Spire’ at right and bronze Astilbe ‘Purpurlanze’ in the background.

And provided that repeated heavy, wet snowfalls do not knock down the plants and ruin the show, the entry garden demonstrates the beauty of the persistent seedheads and stems throughout winter.  The grass at left is Korean feather grass (Calamagrostis brachytricha).

Plants and Memories

Many of the plants in the entry garden are part of Piet Oudolf’s personal history: breeding successes of the German or Dutch plantsmen who were part of his circle – and horticultural education – since the beginning of his design career and life in Hummelo.  People like Ernst Pagels (1913-2007), of Leer, himself a student of Karl Foerster, the iconic nurseryman who sheltered Jews in his nursery during the Second World War and whose name is memorialized in a well-known feather reed grass (Calamagrosis x acutiflora). As explained in Hummelo: A Journey Through a Plantsman’s Life, in the 1980s Piet Oudolf travelled often across the border into Germany to visit Pagels at his nursery where they would talk plants. “We went to get the newest plants, and to bring them home…. and we exchanged a lot.”   Among the Ernst Pagels jewels that live in the TBG’s entry garden are Achillea ‘Walther Funcke’….

Piet’s Dutch friend and fellow plantsman Coen Jansen is responsible for the tall meadowrue Thalictrum ‘Elin’.

And his German colleague Cassian Schmidt, director of the famous garden at Hermannshof, (thanks Tony Spencer for that great blog entry) has his own name memorialized in the beautiful, Kurt Bluemel-raised fountain grass Pennisetum alopecuroides ‘Cassian’, shown here with the statice Limonium latifolium…..

As for Piet Oudolf himself, long before he designed the planting of the TBG’s entry border, he was selecting his own plants and registering them. In 1998, the year before I visited him at Hummelo, he joined with two other growers to launch their company Future Plants, “to market their introductions and to protect their work through Plant Breeder’s Rights.”  As explained in Hummelo: A Journey…, these plants were often put into production in the U.S. before Dutch nurseries had started to raise them.  Among the Piet Oudolf-propagated plants in the entry garden are the pale-mauve hybrid monkshood Aconitum ‘Stainless Steel’….

That concludes the first part of my two-part blog on the entry garden at the Toronto Botanical Garden. In Part Two, I drill down into Piet Oudolf’s garden plan to show you some terrific plant combinations, and some of my favourite plants and why.

PS – if you’re a fan of New York’s High Line, I have photographed the Oudolf plantings there in three seasons, and blogged about a few of those visits as well. Here’s the High Line in early May and a two-part blog on the High Line in mid-June.

This summer, I’m looking forward to visiting Lurie Garden in Chicago’s Millennium Park.
