Finding Beauty & Tranquility at Omaio

While touring New Zealand this January with The American Horticultural Society’s Travel Study Program, we were privileged to visit both gardens with a high degree of human intervention and wild places where nature was the sole designer. But we also visited a garden where the owner had used her skill to meld subtle design with the natural environment in a way that complemented both.

Omaio-Garden Welcome-Sign

Omaio is a Māori word that means “peace, tranquility and happiness”. For Liz Morrow, her 18-acre (7 hectare) property on the Takatu Peninsula an hour north of Auckland is all of those things. What started out in 1980 as a log cabin seaside holiday house (what the Kiwis call a “bach”) became, in 2005, a full-time home.  Now it’s not just a ‘garden of national significance’ recognized by the New Zealand Gardens Trust, but also a Bed & Breakfast.  And it’s been the subject of magazine articles and a garden show.

But back to 2006, when Liz and her son Johny….

Using borrowed garden hose to outline gently curving borders that echoed the curves and waves of Kawau Bay below, Liz cut into the former lawn, planting both exotics and natives that would complement, but not out-compete, the natural setting.

In the sunny garden surrounding the house…..

We were all wowed by the luscious mophead Hydrangea macrophylla ‘Bloody Marvelous’.

Though Liz’s massed clivias and bergenias would have flowered in New Zealand’s spring (our autumn), their foliage and fruit still offered interest in midsummer. This is the fruit of a yellow-flowered clivia.

Liz was the perfect hostess, organizing an alfresco lunch…….

In a nod to the North Island’s prehistoric past, a lifesize moa by Jack Marsden-Meyer made from driftwood and pururi boughs watches over the path from the bush.  The sculpture recalls the flightless bird – this one, the North Island giant moa (Dinornis novaezealandiae)  was estimated to stand at 3 metres (10 feet) – that was hunted to extinction by the Polynesians, the first humans to reach New Zealand in the 13th century.

Rounding into the shade, a native New Zealand hens-and-chicks fern (Asplenium bulbiferum) caught my eye.  Note the tiny ferns arising from bulbils on the mature fronds.

Festival Theatre Garden – Stratford

For the first time in more than 20 years, I spent a few days this month at Ontario’s venerable Stratford Festival. (For the record, we saw Guys & Dolls – highly recommended; HMS Pinafore – fun Gilbert & Sullivan; and The Changeling – read a story précis before seeing!).  We walked along the Avon River on our way to the first play, and I thought for the thousandth time how lovely our native wildflowers look in early autumn. This is heath aster (Symphyotrichum ericoides) with lots of bees!

Symphyotrichum ericoides-Heath aster-Avon River-Stratford

The entire countryside around Stratford is gorgeous in September, with rows of tall corn and nearly-ripe pumpkins filling the fields near Highway 7 as you drive in. In fact, it’s one of the beautiful farms in the area that renowned singer Loreena McKennitt calls home. I interviewed her in Stratford for a story I proposed and wrote for Chatelaine Gardens! magazine some 21 years ago.

Loreena McKennitt-1997-Chatelaine Gardens

A few summers later, I visited Stratford to photograph the new garden at the Festival Theatre for a story I proposed and wrote for Landscape Trades Magazine.  Having opened in 1997, it was under the expert care of Stratford Festival head gardener Harry Jongerden, who is now Executive Director of the Toronto Botanical Garden.

Landscape Trades-1999-Festival Theatre Garden

Returning to Stratford this month, I was excited to see how the garden had weathered over the past few decades and, especially, to see what was in bloom in the first week of autumn.  Since my magazine story was published such a long time ago, I’ll take the liberty of quoting it from time to time here, as we tour the plants – like this lovely Japanese anemone (Anemone x hybrida ‘Whirlwind’).

Anemone x hybrida 'Whirlwind' - Festival Theatre

***********

Two hours west of Toronto, on a hill overlooking the Avon River, sits the Festival Theatre, main stage and head office for Canada’s renowned Stratford Festival. Since its first production in 1953, a play directed by Tyrone Guthrie, starting Alec Guinness and mounted under a canvas tent, the Festival has enjoyed wide critical acclaim, and Stratford has become a mecca for theatre lovers — and garden lovers. Isn’t this swamp hibiscus (H. moscheutos) spectacular?

Hibiscus moscheutos-Swamp hibiscus-Festival Theatre Garden

In 1997, the Festival Theatre (one of three in Stratford used by the festival) underwent a major renewal under the direction of Toronto architect Thomas Payne, then of KPMB Architects, now with Thomas Payne Architect.  Trained at Yale and Princeton and one-time protégé of Barton Myers, Payne’s work includes the ethereal Fields Institute for Mathematics at the University of Toronto, a new home for the National Ballet of Canada, the much celebrated Tanenbaum Sculpture Gallery at the Art Gallery of Ontario (AGO), the restoration of the Goodman Theatre in Chicago and the Young Theatre for the Performing Arts (Soulpepper). His work at Stratford involved indoor renovations such as changing the rake of the theatre floor to create more spacious seating; adding technical gutters and an acoustical canopy; and renovating the lobby.  And with the collaboration of Toronto landscape designer Neil Turnbull, Payne created The Arthur Meighen Gardens, named for Canada’s ninth prime minister and funded, in large part, by the Meighen family foundation. It  was a new garden that was as rich in theatrical allusion as it was in stone and plants.

Arthur Meighen Gardens-Festival Theatre

A horseshoe-shaped entrance driveway lined with concrete arbor columns, each one draped with a clematis in early summer – or morning glories in late summer — encircles the garden.  “At night,” Payne told me then, they look like Noguchi lamps.”

Anemone x hybrida & Festival Theatre Lights

The columns, each dedicated to a local benefactor, are clothed in a sock of inexpensive, water-repellent canvas symbolizing the canvas roof of the first performance tent.

Ipomoea tricolor-Morning glory-Festival Theatre

The garden is a fragrant, romantic tumble of perennials, designed to be in bloom as the curtain rises in mid-April, and still have something in flower for October’s final curtain call.  In late September, ligularia and blackeyed susans (Rudbeckia fulgida ‘Goldsturm’) are still providing colour as the ornamental grasses begin to flower.

Ligularia & rudbeckia-Festival Theatre Garden
Of the garden’s hard structure, Thom Payne said:  “We wanted a great stone wall with greenery growing on it.  The concept is quite mathematical. It’s a cribbage – a series of limestone terraces – that fall away on a grid toward the lowest point.”  Typical of Mr. Payne’s tendency to use the landscape to hint at what can be found indoors, the main path travels through the garden and over the bridge above the formal lily pond – all on the axis of Aisle 2 Entrance Lobby.  “It plays a prominent role in delivering people to the front door.”

Festival Theatre Garden walkway

In creating the cribbing for the terraces, Payne was mindful of his budget but still wanted the natural appearance of stone.  He used pigmented, specially-finished, architectural concrete as an inexpensive foundation for the walls.  He then capped it with 6-inch split-faced Eramosa limestone from local quarries.  “There are a lot of things,” he says, “that are extremely cost-effective, yet I think the overall effect is one of richness, theatricality and permanence.”  Below is a sturdy, gold yarrow (Achillea filipendulina) with a deep red swamp hibiscus.

Yarrow-Achillea filipendulina-Festival Theatre

When it came time to plan the 32 terrace beds, Neil Turnbull drew on a long career as one of the country’s most inspired plantsmen and landscape designers.  In seeking a theme, he hit upon another powerful symbol of early Shakespeare theatre, its festival banners and ribbons.  “I decided to create three ribbons of thyme that flow like curving rivers through the beds,” he explained. (The thyme is evident in the magazine cover above but I suspect other perennials have overwhelmed it somewhat over the years.)  Below is Japanese anemone with blue leadwort (Ceratostigma plumbaginoides).

Anemone x hybrida & Ceratostigma plumbaginoides-Festival Theatre Garden

Known for solving geometry on the drafting table but aesthetics on-site, Turnbull reasoned that the garden’s strength would be in the sheer massiveness of its plantings.  He had 21,000 plants expressly grown, and then placed them in recurring combinations throughout the beds.  In late summer, some of our wonderful natives provide spectacular colour, like goldenrod (Solidago sp.) and magenta-purple New England aster (Symphyotrichum novae-angliae) below.

Lots of fall asters have been used at the theatre, like ‘Andenken an Alma Pötschke’, below, with a honey bee nectaring….

This summer has seen an extraordinary amount of rain and below-average temperatures until September, when we had a heat wave. So some plants had already begun to undergo a foliage change, like spring-flowering Euphorbia griffithi ‘Fireglow’, below.

As visitors reach the top of the planting beds on their way into the theatre, they cross a bridge over a formal rectangular pool…

As I left the garden, I noted all kind of pollinators flitting about. I saw bumble bees foraging deep in the yellow wax bells (Kirengeshoma palmata)…..

Almost twenty years after my first visit, it was good to see the garden still looking gorgeous and being enjoyed by thousands of theatre-goers annually — plus untold numbers of tiny buzzing and fluttering visitors, too.

The Festival Theatre gardens are located at 55 Queen Street, Stratford, Ontario.  The Festival is open from mid-April to the end of October; for more information visit the Stratford Festival website.

In the Garden with Barbara & Howard Katz

Barbara Katz and I became Facebook friends a few years back, drawn to each other by our mutual love of colour combinations in plant design and also our great admiration for Dutch garden designer Piet Oudolf. In fact, it was on Barbara’s recommendation and with her introduction that Piet was commissioned to design a meadow garden for Delaware Botanic Gardens, being planted this fall. So it was with great anticipation that I made plans to attend the 2017 Garden Bloggers’ Fling in the Washington DC Capitol Region, a 3-day event that included a tour of Barbara & Howard Katz’s Bethesda, Maryland garden. We even decided to have dinner in a Washington restaurant before the tour, meeting face to face for the first time. (Our husbands got along famously too!)  And when our bus pulled up on Barbara’s street a few days later, it was easy to see which house was theirs for Barbara and Howard, an architect, were there waiting to welcome us.

Barbara & Howard Katz-Bethesda

But even if they hadn’t been out front, we would have known the house. Their luscious front garden (below) presented a welcome right at the street with a generous bed of summer perennials, carex grasses and succulents arrayed around an old ‘Halka’ honeylocust tree. Barbara, who has 30 years experience in garden design with her company London Lanscapes LLC, said that this bed, installed in mid-April while creating a new flagstone path, gave the front a needed facelift and some interest and pleasure for passersby. It was also a way to reduce the amount of front lawn and provide a buffer against dogs and snow.  But most important, as a plantswoman: “I needed MORE space to play with plants.”  Not surprisingly for a designer who knows how to use colour, there is a clever and subtle use of red flowers in this garden – the gaillardia at front and the echinacea in the rear – that carries the eye up and back toward the red chairs on the porch, the oxblood-red door, the red window shutters and even the Japanese maple.

Barbara Katz-Street Garden & House

Barbara worked the soil in the street garden to make it free-draining. “It gets baked in the afternoon,” she said, “So now I can use plants I hadn’t been able to before” (like the yuccas, below).

Sun-loving plants-Barbara Katz

I adored the beautiful iron scroll edging – staking out the property line with airy elegance. Barbara found it online at Wayfair

Gaillardia-Barbara Katz

The ‘Blue Boa’ anise hyssop (Agastache hybrid) was attracting lots of bumble bees.

Bumble bee-Agastache 'Blue Boa'

The veranda, below, is everything a good front porch should be: an attractive welcome for visitors, a well-appointed anteroom to the house itself and a place to relax comfortably with a view of the garden and street. Too often we restrict our seating areas to the privacy of a back yard where none of the neighbours can spot us reading a newspaper or sipping a glass of wine. But why?  A covered veranda is a sanctuary in the rain and obviously has a completely different outlook on life (and the neighbourhood) than the sitting areas we create out of view. Let’s tote up the good things about Howard’s and Barbara’s version. But first of all, a little background. When Barbara first saw this house, it was as a designer for the owner, who would have her redo the entire garden, including the complex topographical challenge at the back (more on that later). The year was 1995; the garden was installed in 1996. Fast forward six years and the house was for sale and Barbara and Howard bought it, including the garden she’d designed, worked with over the years, and come to love. As for the veranda, it was bigger then, with small wooden posts and railing, and a concrete bases and steps. Howard needed an office, so they took half the veranda and incorporated it into the house; removed the railing; used Azek (a plastic-wood product) to make the posts chunkier; rebuilt the steps to give them generous 18-inch treads with stone risers; then refaced everything with stone veneer. Add some Arts & Crafts lights, pots of easy-care succulents (can we get a cheer for iron plant stands?), a few handsome pieces of sculpture; and comfy chairs and it’s one of the prettiest makeovers ever.

Veranda-Barbara & Howard Katz

All the succulent containers, by the way, are Howard’s creations. He was born in South Africa where many succulents are native; they add their own textural note to Barbara’s herbaceous side of the ledger.

Wouldn’t you like to fall asleep in one of these Adirondack rockers? And another little colour tip, courtesy of the glazed green pots (as devotees of the artist’s colour wheel know): red and green are complementary contrasts and they always combine nicely with each other. I can only imagine how beautiful this foundation planting must look as the Japanese maples turn colour in autumn!

Adirondack Rocker-Barbara Katz

Let’s head around to the back, passing a little treasure trove of Howard’s succulents as we go.

Succulent collection-Howard Katz

The back garden is where the challenge lay for Barbara when she first saw it more than two decades ago. With a 12-foot elevation change from the back door up to the property line, it called for creative terracing. In the photo below, (when I got home, I realized I didn’t have a workable shot of the slope and asked Barbara to take a photo, which shows one side), you can see how beautifully the rich tapestry of perennials and low evergreens creates a frame for the cascading water feature.

Slope-Barbara Katz

In my experience, a designer who loves plants and knows how to combine them while also mastering the art of hardscaping is a rare individual. Barbara is skilled at both. Plants with purple, white and orange flowers and leaves are on one side….

Slope-Plantings-Barbara Katz

…including this butterscotch combination of carex and heuchera with peach echinacea and anise hyssop….

….while blues, yellows, pinks and maroons (below) are on the other side….

Echinacea & Coleus-Barbara Katz

But it’s the stone workmanship on the hillside that really impresses me. Let’s climb up the stairs, which have an excellent tread:riser ratio that makes navigating the slope easy…

We’ll pass some more of Howard’s delectable succulent confections on the way, like this one…

The woman knows colour!

Barbara Katz-Mosaic table

I’m not sure how many people would take note of this small detail, but for me it stood out as a superb way of disguising the necessary nuts-and-bolts of slope retention. The concrete block wall between the Katz property and the one behind them has been stained dark green – and presto! it vanishes. Well, except for the sweet little plaque to pretty it up. That airy iron trellis above it is Howard Katz’s effort to keep leaf-munching deer from leaping from the neighbour’s garden into theirs.

Stained Concrete Block Wall-Barbara Katz

There are lovely little touches of art in the garden, like this ‘bluebottle fly’….

And a wire grasshopper, among many other pieces.

But the big focal point in the back garden is the terraced water feature. From the stone patio behind the house, this is what it looks like gazing up the slope.

There are tropical waterlilies in the pool at the bottom, and goldfish.

I would have loved to linger a little, perhaps in the comfy seating near the house. Doesn’t the soft kiwi green look gorgeous with the sage green of the wall?

But it was time to get on the bus and head to our next garden.  Thank you Barbara and Howard, for your generosity and creativity. You are both inspiring!

Rhapsody in Blue: Linda Hostetler’s Virginia Garden

During last month’s Garden Blogger’s Fling in the U.S. Capital Region, (and following my visit to Washington DC’s fabulous Dumbarton Oaks and Thomas Jefferson’s Monticello near Charlottesville VA), I was delighted to find myself meandering through the garden of fellow color connoisseur and Facebook pal, landscape designer Linda Hostetler. I’ve long admired her photos so it was a pleasure to wander the paths exploring her amazing textural plantings. But there was definitely a color theme running through Linda’s garden, and I loved ticking off all the ways she manages to celebrate ‘blue’. So let’s take a little tour, starting in the front garden of Linda and Ralph Hostetlers’ pretty home in Plains, Virginia, not far from Washington D.C. The tapestry-like plantings here, while very lovely, don’t really prepare you for the immense scale of the back garden.

House-Linda Hostetler

Let’s walk down the side path with its playful boxwood balls.

Path-Linda Hostetler

You might catch the light glinting off the sweet mirrored suncatcher….

…. and at the end of the path, any one of hundreds of interesting plants might catch your eye like the native Indian pink (Spigelia marylandica).

But look up and gaze around and you’ll be struck by the flashes of azure and turquoise shimmering in every corner of Linda’s garden. How does she love blue? Let us count the ways.

Furnishings 

Like a little sense of occasion? Walk into Linda’s garden and you’re passing under a blue arch.  Doesn’t that curved boxwood allée make you want to start exploring? And look at the blue-toned hosta in the rear.

Arch-Linda Hostetler

Want to rest a minute in a little bit of shade? These blue umbrellas (there were several) and tables and chairs were popular spots for relaxing when masses of garden bloggers were trying to escape the June heat.  And don’t you love that spectacular pairing of ‘Lucifer’ crocosmia with the furnishings?

Art

Little artistic touches in blue abound in Linda’s garden – like these metal spheres in blue and contrasting yellow.

And no southern garden is complete without a bottle tree – this one sprouting cobalt blue bottles. (If I’m not mistaken, those are Harvey’s Bristol Cream sherry bottles….)

A glazed ceramic globe is an easy way to give a blue punch to the border, especially contrasted with bright-red coleus (Plectranthus scutellarioides).

Plants

It was such a sunny afternoon with so many people running through the garden, I gave up trying to get landscape shots. But I did love seeing this little water feature with purplish-blue pickerel-weed (Pontederia cordata). It’s a favourite of bumble bees (and me).

And then, alas, it was past the blue hydrangea and back on the bus to continue our tour of Virginia gardens. Next time, Linda, we will hopefully meet in person in your lovely garden (not via blog!)

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.

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

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

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).

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.

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.

11. Sea lavender (Limonium latifolium) and dense blazing star (Liatris spicata)

Design-Limonium latifolium & Liatris spicata-Piet Oudolf garden-Toronto Botanical Garden (2)

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.

12. ‘Royal Purple’ smokebush (Cotinus coggygria) & ‘Amazone’ Jerusalem sage (Phlomis tuberosa)

Design-Cotinus coggygria 'Royal Purple' & Phlomis 'Amazone-Piet Oudolf border-Toronto Botanical Garden

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.

2.‘Cassian’ fountain grass (Pennisetum alopecuroides), here with ‘FIretail’ red bistort (Persicaria amplexicaulis)

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.

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.

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.

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.

Honey bee on Calamintha nepeta ssp. nepeta

‘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.

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.”

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.

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

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.
