Cruising the Eastern Arctic – Sunneshine Fjord

It was our fourth day in Nunavut cruising aboard the MV Sea Adventurer. After our initial visits to Iqaluit and Pangnirtung, we were now heading towards Cape Dyer, which in a few days would be roughly our departure point across the Davis Strait to Sisimiut, Greenland.

Fog blanketed the Arctic, which meant, for the captain, it was slow going.

In the lounge, Heidi Langille, who resides in Canada’s capital city Ottawa, gave an afternoon lecture on what it was like to be an “urban Inuit”.

That evening after dinner, there was music on deck and Heidi and our other Inuit cultural emissaries demonstrated some traditional games of strength…..

….. while we cheered them on.

The next morning, the sun was warm on the east coast of Baffin Island as we made our way up the appropriately-named Sunneshine Fjord –   also seen as Sunshine Fiord in some references….

….and dropped anchor.   

The zodiacs ferried us to a wet landing on shore. It’s interesting that, if you’re a resource staffer on an Adventure Canada expedition, you must also know how to captain a zodiac. That goes for (now retired) art and culture director Carol Heppenstall, standing in the blue life-vest to the left of (now retired) expedition leader Stefan Kindberg.

When you land on an unoccupied shoreline in Nunavut, there’s a good chance that even though there are no human occupants, there may well be polar bears. Thus, our expedition leader Stefan Kindberg carried both a handgun and rifle. Fortunately, he’s never had to use them, and commented dryly: “You don’t ever want to have to shoot a polar bear in Canada. Too much paperwork!”

We were invited to explore the landing area. We could stay on the beach, work our way around the lower slopes, or climb right to the top.

My husband Doug (below) elected to stick near the shore.  I was happy we’d purchased new walking poles….

….and, again, I was delighted with my new rubber boots. Wearing them, I was able to shake up a lot of green algae in the shallow water of this intertidal zone.

I loved looking at the seaweed.  So many different species….

….. each with its own ecological community….

….. and adapted to the seasonal mix of salt and fresh glacial meltwater in the fjord.

Some of our group elected to climb to the summit, but I was most anxious to botanize on the lower slope.

This part of Sunneshine Fjord was a perfect place to be. The moraines were gently sloped, the sandy beach quite wide, the fjord deep enough for our ship, and these slopes – so monotonously featureless and olive-brown as the ship sails past them – were absolutely brimming with plant life.

Unless you get closer, you might not guess that those lighter areas on this hillside….

…… are colonies of mountain avens (Dryas integrifolia) wreathed in creeping willow shrubs.

Or that these paler drifts….

…… are Arctic heather (Cassiope tetragona), sometimes punctuated with hairy lousewort (Pedicularis hirsuta).

Here’s a closer look at hairy lousewort to illustrate the trait that earned its name.

Morning dew was still on this pair of natives: Arctic harebell (Campanula uniflora) with large-flowered wintergreen (Pyrola grandiflora).

Arctic cinquefoil (Potentilla hyparctica) is a circumpolar species, also native to Alaska, the Yukon and Norway’s Svalbard archipelago. 

Arctic blueberry or bilberry (Vaccinium uliginosum) would bear its fruit in August – with only birds and small mammals to appreciate it.

A butterfly was nectaring on moss campion (Silene acaulis).

Arctic poppies (Papaver spp.) were in flower….

….. and dwarf fireweed (Chamerion latifolium), too.

Moss had colonized the rocky outcrops in the damper areas.

There was runoff from the small glaciers beyond the summit.  Though Sunneshine Fjord is not directly related to Baffin Island’s Penny Ice Cap, it has (like all parts of the Arctic) drainage from abundant snow and ice on the upper elevations.

Here we see Arctic willow (Salix arctica) clinging to a boulder beside the waterfall.

Arctic willow grew everywhere on our expedition. One of thirteen species native to Nunavut, it grows farther north than any of the other willows and is the most common willow on Arctic islands.  Usually prostrate, it can also change its growth habit in certain circumstances and become erect, with a height up to 1 metre (3 feet).  Its hairy leaf reverse is a distinguishing characteristic, versus the similar-looking northern willow (Salix arctophila), which has glabrous or smooth leaves.  It can be very long-lived, with a Greenland specimen dated to 236 years.  Its leaves are edible and Inuit people traditionally peeled and chewed the roots of this plant they call suputiksaliit to relieve toothache – recalling the general pharmaceutical use of salicylic acid derived originally from certain Salix species as aspirin (now made synthetically).  When Arctic willow seeds ripen, they are surrounded by fluffy hairs (willow cotton) that help them disperse on the wind.

I spotted some bearberry willow (Salix uva-ursi) as well, but I was most interested in the beautiful black lichen on this rock, sensibly called black lichen (Pseudephebe minuscula, formerly Alectoria).

Here you can see how black lichen develops and grows. The study of the growth rate of lichens, by the way, is called lichenometry.

Some of the resource personnel were capturing the scene on the lower slope. This is Kenneth Lister, now retired as a curator of Arctic anthropology at the Royal Ontario Museum.  

Dennis Minty, below, is a well-known photographer on many Adventure Canada expeditions.

It was challenging to walk back to the beach through the glacial debris field.

This cobble sandbar jutting out from the beach was raised enough that I was able to make our ship look like it was sinking.

The air on the last day of July was quite warm and wisps of advection fog came and went above the cold Arctic waters.

Walking back to the beach where the zodiacs waited, I was fascinated by the stunning rock formation below, exposed by the ocean waves (and perhaps glacial ice?) along the fjord. It was beautiful and mysterious. Until this week, I hadn’t made a serious effort to discover more. This is, after all, a very isolated part of Nunavut: perhaps some Inuit fishermen come in here, the odd scientific expedition, and a handful of summer adventure cruises over the decades,(sea ice and weather willing).

The rocks, though fractured, were beautifully banded, similar to the banded gneiss, below, that I love photographing on the highway near our cottage on Lake Muskoka north of Toronto. A Precambrian rock, it is part of the Grenville Province (Muskoka Domain, Moon River Lobe) and is dated to about 1.4 billion years before the present, i.e. the Paleoproterozoic Eon (literally “before animals”).

Could my Sunneshine Fjord rocks be that old? I reached out via email to some geologists whose names I found online associated with the Cumberland Peninsula or Cape Dyer just north of the fjord. At one time during the Cold War between the west and Russia (1958-92), Cape Dyer was a radar station and part of the DEW Line, the Distant Early Warning System. Today it’s one of 40 sites across the north that has had to be cleaned up (at a cost of $575 million) to get rid of contaminated soil, fuel tanks and other debris.

I received a nice email in response from Dr. John T. Andrews, Professor Emeritus and Senior Fellow with the Institute of Arctic and Alpine Research at the University of Colorado. He had done glacial/climate change research near Cape Dyer and wasn’t sure about my rock, but kindly sent me the abstract for another geologist’s paper on the region’s volcanic history. This paper describes the field relations of Tertiary basalts which are preserved as small patches intermittently along the coast for 90 km northwest from Cape Dyer, Baffin Island. The flat-lying, subaerial lavas generally rest directly on the Precambrian basement but in some localities a thin sequence of terrestrial sediments intervenes between the basement and the volcanics. Where the sediments occur, the overlying volcanics tend to be divisible into a lower unit of subaqueous volcanic breccia and an upper sequence of subaerial flows. In age, stratigraphic position and magma-type, these volcanics strongly resemble those of the basalt province of west Greenland. A model is presented for the generation of both provinces in a single volcanic episode, related to the opening of Labrador Sea – Baffin Bay by continental drift.

Wow! A volcanic episode had ruptured Greenland from Baffin Island? I suppose I should have studied up on the basic tectonic relationships of the Eastern Arctic before going further. But my banded rocks in Sunneshine Fjord didn’t look like the columnar basalt formations from the Columbia River Basalt Flood, below, that I had photographed in northeast Oregon two years ago and written about in my blog on Oregon’s Thomas Condon Paleontology Center.

After a few days of searching on Google, I must have put in some magical search parameters (fiord, not fjord, etc.) and came up with a Research Canada page containing a full geological map of the area around Sunneshine Fjord, below!

http://publications.gc.ca/collections/collection_2013/rncan-nrcan/M183-1-6-2011-eng.pdf

When I enlarged the map, I thought I could spot the exact area with the cobble sandbar that we had visited, marked with a red arrow below!

Detail from http://publications.gc.ca/collections/collection_2013/rncan-nrcan/M183-1-6-2011-eng.pdf

The lead author was geologist Dr. Mary Sanborn-Barrie. I sent off an email with photos of my rocks, but didn’t hear anything back right away. Maybe she was in the field, out of wifi range, dubious about such a random email from someone she didn’t know? But then I received a reply from her and it made me so happy. Because my rocks were old, really really old!

Hi Janet

What a beautiful exposure of rocks you were able to explore on the shoreline. Our mode of transport was helicopter drop-off and then walking all day, so we rarely (if ever) got to map such gorgeous wave-washed exposures.

Actually your photographs appear to be of the oldest rocks in the region, rather than the youngest! They appear representative of the deformed and layered Archean (A) tonalite gneiss (tg) basement (unit Atg in the legend below) that underlies much of Cumberland Peninsula and which is dated at two localities at 2,990 million years old and 2,940 million years old.  The pale grey layers are foliated tonalite and any biotitic and/or mica-rich layers (unit Asp in the legend below) are likely even older sediments that were intruded by the tonalite.  Upon closer inspection, such mica-rich may also contain garnet and/or silky silvery sillimanite – both minerals diagnostic of high-alumina sedimentary rocks.

Here’s an enlargement of the legend to which she referred:

Detail of legend http://publications.gc.ca/collections/collection_2013/rncan-nrcan/M183-1-6-2011-eng.pdf

I was so happy I’d made closeup images of the rock layers, below. Imagine! These Archean rocks at 2.99 – 2.94 Ga (Giga annum or billion years) are twice as old as the rocks on the highway near my cottage, from an eon whose name comes from the same root as “archaic” stretching back 4 billion years.

I had photographed the upper slope from the beach, below, and all I could see was more of the same, but there were, in fact, some much younger rocks in places at the top of the cliffs on Sunneshine Fjord. Dr. Sanborn-Barrie included information about those rocks as well, as she continued in her email (below my photo).

These tectonically layered rocks (as opposed to the bedded (primary layering=strata) observed in the Tertiary sequence) underlie (that is, they are low on the cliffs) the much younger, unconformably overlying Tertiary basalts that erupted about 60-55 million years ago during spreading of the Baffin basin. She also enclosed a photo of herself examining those overlying Tertiary basalts with a view across the fjord to basalts atop the ancient rock.

Photo of geologist Mary Sanborn-Barrie by mapping co-leader, geologist Michael Young

And she provided an info-card using a photo from Sunneshine Fjord showing what is meant in geology by “unconformably” or “unconformity” (n.): meaning “a series of younger strata that do not succeed the underlying older rocks in age or in parallel position, as a result of a long period of erosion or nondeposition.” Thus, we don’t know what happenened here between 2.9 Ga and 60-55 Ma because all the physical evidence for that vast period has disappeared. That break in the record is called a “hiatus”.

Returning now to that wonderful last day of July in 2013, it was time for us to climb into the zodiacs, board the ship and take our leave of Sunneshine Fjord.

It was so warm outdoors that a barbecue lunch was served on the rear deck……

…… complete with grilled chicken and steak.

Passing an iceberg…..

…..we bade farewell to the coast of Baffin Island, Nunavut and Canada.

Hours later, I was happy I hadn’t consumed too much wine at that lovely lunch because I was flat on my back in my bunk, having taken a motion sickness pill and given up on trying to read. Every now and again, I’d pull myself up to look out the window at the 9-foot swells that had the ship rocking back and forth like a slow amusement ride… for hours and hours.  My husband, who doesn’t get seasick, returned from dinner and announced cheerily: “Well, you’re in the majority! And some people left the dining room in a big hurry!”  I groaned and closed my eyes and thought of a young Charles Darwin, often seasick in his hammock on his five-year voyage aboard The Beagle.  “I hate every wave of the ocean, with a fervor,” he wrote to a cousin in 1835.

Fortunately, morning did come, the seas calmed, and we arrived on a sunny August 1st on the west coast of Greenland. Coming up in my next blog: Sisimiut.

Cruising the Eastern Arctic – Iqaluit

Next week, we were to have flown to Stockholm to board a ship that would take us through the Baltic Sea. I had booked an extra few days in Sweden at the beginning in order to visit the Linnaeus Garden in Uppsala, long a destination on my botanical bucket list. The cruise included Helsinki, St. Petersburg, Talinn (Estonia), Gdansk (Poland), Berlin, Copenhagen and Alborg (Denmark) and three stops in Norway. I added a short flight from Bergen to Edinburgh en route home to visit the Royal Botanical Garden there, another botanical bucket list must-see. Like everyone’s travel plans in pandemic times, our trip was cancelled.

I know a lot of people who disdain cruises, but the few we have taken have been a wonderful way to nimbly visit a series of far-off places that we would not have seen otherwise. One cruise, on a small French ship, was to the Greek islands and the Turkish coast. Another was what I call a ‘tasting tour’ of Southeast Asia from Bali to Bangkok on a relatively small ship. But my favourite and the most unusual was our 2013 cruise through the Eastern Arctic with Adventure Canada and ROM Travel (Royal Ontario Museum), and I thought it would be fun to recall it here on my blog. It began with a charter flight on First Air from Ottawa…..

…… over the tundra and Hudson Bay….

…..  to land at the cheery, yellow terminal in Iqaluit, the capital of Nunavut, one of Canada’s three northern territories, the others being Yukon and Northwest Territories. Originally called Frobisher Bay, the capital’s name was changed in 1987 to its original Inuktitut word Iqaluit, meaning “place of many fish”.

Shortly after we left the airport, I saw my first patch of dwarf fireweed (Chamerion latifolium), below. I was excited!

After a brief stop at the Legislative Assembly of Nunavut…..

….. built in 1999 when the region was officially declared a Territory of Canada with a consensus government (no political party)….

…. we departed for Sylvia Grinnell Territorial Park.  The park is named for the daughter of the New York man who helped to finance American explorer Charles Francis Hall’s expedition to the region c. 1860.  There were informal lectures here, but I was most interested in seeing the flora.

Nunavut has a very short summer window for plants to emerge, flower, fruit and set seed, so our visit on July 27th meant it was the perfect time to see a large selection of natives in bloom. Though it didn’t look promising for those used to seeing large perennials, shrubs and trees (of which there are none here), the ground was a tapestry of tiny treasures.

Best of all, Adventure Canada employed a naturalist named Carolyn Mallory…..

…. who had co-authored Common Plants of Nunavut (which I bought on this trip).  Carolyn would get used to me asking her about plants throughout Nunavut and Greenland.  I have used information in her excellent book to describe the plants I saw at Sylvia Grinnell Park.

That white flower Carolyn is pointing out above is northern Labrador tea, a prostrate member of the rhododendron genus, R. tomentosum subsp. decumbens.

The park was full of plants I had never seen ‘down south’. This is the dwarf shrub white heather (Cassiope tetragona).  Its Inuit name isutit means “fuel for the fire”.

This is Arctic harebell (Campanula uniflora).

Yellow mountain saxifrage (Saxifraga aizoides) is one of many saxifrages in the Arctic.

Lapland pincushion (Diapensia lapponica) is a tiny shrub, barely inches above the ground. Its Inuit name is piriqtut nunaralikuluit.

This was a pretty combination: yellow alpine arnica (Arnica angustifolia) with purple mountain heather (Phyllodoce caerulea).

Mountain avens (Dryas integrifolia) is another dwarf shrub that rarely exceeds 15 cm (6 inches). In winter its leaves die off but gradually accumulate a thatch that helps conserve moisture in summer.

Yellow oxytrope (Oxytropis maydelliana) has a carrot-like taproot that was traditionally fried with whale blubber or seal fat and eaten as a vegetable (airaq) in spring.

Large-flowered wintergreen (Pyrola grandiflora) is a beautiful little perennial with fragrant flowers. Its leaves turn bright red in winter.

We would see tufted saxifrage (Saxifraga tricuspidata) in many locations on our expedition.

I loved the tiny vignettes that these small plants created with their neighbours. This is moss campion (Silene acaulis) wreathed with net-vein willow (Salix reticulata), one of Nunavut’s thirteen native willow species.

Arctic bladder campion (Silene involucrata) has fused sepals that create a striped bladder that you can see at left.

Arctic poppies (Papaver sp.) look very much alike but can belong to a number of different species, mostly distinguished by variations in leaf lobes and hairs on the leaf reverse or capsules.  On the Nunavut Coat of Arms, poppies represent the summer season.

This is flame lousewort (Pedicularis flammea) and though the sunlight was a little too harsh for photography at this point in the Iqaluit afternoon, you can see why the leaves cause the plant to sometimes be mistaken for a fern before flowers appear.

Look at the beautiful blossoms of mountain cranberry (Vaccinium vitis-idaea subsp. minor). Soon there will be shiny, red berries that are evidently sweeter once they’ve gone through a first frost. Inuit people call them kimminait.  Inupiaq people from Alaska often mixed them with meats or fish, storing them underground over winter in birchbark baskets.

I would have a very difficult time separating out the prostrate willows, but Carolyn listed Salix arctophila on her plant list from our day at Sylvia Grinnell, so I’m assuming that’s the identity of the plant below.

However, with Carolyn’s finger for scale, there was no mistaking the tiny leaves of Salix herbacaea, which is one of the world’s smallest shrubs.

Soon our visit to the park ended and we were bused to the shore to climb into one of several zodiacs to ferry us out to…..

….. our home for the next 10 days, a retrofitted 1975 Yugoslavian-built polar cruise ship called MV Sea Adventurer (now renamed the Ocean Adventurer). Though not technically an icebreaker, it has an ice-hardened hull and is listed as an A-1 Ice Class ship capable of negotiating smaller pieces of sea ice.   It was time to begin our adventure in the waters of Nunavut and Greenland…….

….. and watch our first sunset over the Arctic Ocean.  Stay tuned for more.

The High Plains Environmental Center

Long ago, in the mid-1990s, I attended a presentation here in Toronto on “new urbanism”. It was focused on a development and planning approach that sees communities built according to principles of diversity of use and population; pedestrian and transit opportunities rather than being centred on automobiles; accessible public spaces and institutions; and a “celebration of local history, climate, ecology, and building practice.” (Source: Congress for The New Urbanism). One of the speakers was a local developer who was keen to build a community featuring many of the tenets of new urbanism. I was fascinated by his dream but secretly felt he would have a tough time competing economically with the treeless subdivisions of cookie-cutter, chock-a-block houses springing up north, east, and west of Toronto’s urban core. My city’s developers had been paving farm fields for years to build residential shrines to sprawl and the automobile. Yes, they were ‘affordable’ suburban homes for the middle-class in a growing metropolis of more than 6-million people, but any vestiges of natural or cultural heritage were erased in a bid to streamline lot servicing and maximize profits.

I was reminded of this a few days ago while reading in the paper about one of Toronto’s most successful subdivision builders. He demolished a $48-million house he’d purchased in seaside Florida a few years back in order to spend perhaps an equal sum to build an “ecomansion” for his family, utilizing net-zero energy but with enough garages for his many cars. And, of course, he flies there via private jet.  I do not begrudge anyone their profits; he took a lot of financial gambles and lost money here and there along the way, especially during the 2009 recession.  He is also a generous philanthropist. But it seems strange and counterintuitive to me that environmental principles are not part of an intelligent development business plan for every economic level of new home ownership.

So I was delighted last June during my annual Garden Bloggers’ Fling to visit the High Plains Environmental Center (HPEC) in Loveland, Colorado in the northeast part of the state. Here, an hour’s drive north of Denver in a 3000-acre mixed use development called Centerra, environmental principles are a major selling feature. Begun in 2001 by McWhinney Enterprises on land homesteaded and farmed by their family from 1866, Centerra includes retail businesses, office buildings, restaurants and residential neighbourhoods. The homes were built by McStain Neighborhoods, co-founded by green building pioneers and architects Tom and Caroline Hoyt. Both the McWhinneys and the Hoyts understood that there is a great cachet to building not just houses, but sustainable environments, in which people can feel connected to the land around them. Part of that initiative was the creation of the High Plains Environmental Center, occupying 100 acres of land surrounding two lakes comprising 175 acres of open water which are reserved for waterfowl. HPEC also manages 135 acres of common space belonging to the landowners in Centerra. Its educational visitor center was opened in 2017, a small building fronted by a lush meadow of native plants…..

…. including delicate blue flax (Linum perenne var. lewisii)……

…. and my favourite of all the penstemons, beautiful pink Palmer’s beardtongue (Penstemon palmeri).

Though we’d been told to make our way through the building, I had to stop for a few moments and enjoy the plantings in the parking lot, especially this border of labelled native perennials and shrubs…..

…. including gorgeous blue Rocky Mountain beardtongue (Penstemon strictus) and golden columbine (Aquilegia chrysantha var. rydbergii).

And as a photographer of bees, including bumble bees, I was delighted to spend a few moments tracking a new species for me, the Nevada bumble bee (Bombus nevadensis), which was busy foraging on the penstemon.

On returning from Colorado last June, the first blog I wrote was called Penstemon Envy. There are simply so many beautiful penstemon (aka beardtongue) species to see in early summer. This is pine-leaf penstemon (P. pinifolius).

Large-flowered beardtongue (Penstemon grandiflorus) with its semi-succulent leaves is one I grow at my cottage north of Toronto. For me, it behaves as a biennial, making its rosette the first year and flowering the second.  Imagine how inspiring these native plants are for the homeowners in the neighbourhood!

Growing amidst rugged Colorado sandstone boulders was beautiful sulphurflower buckwheat  (Eriogonum umbellatum), along with orange California poppies (Eschscholzia californica).

Prince’s plume (Stanleya pinnata) is a spectacular native plant that we would see in other Denver gardens on our fling. As well as being a larval host to two species of butterfly, it was also a traditional medicinal plant for many Native American peoples.

I passed the sign that marks Centerra’s certification as a Wildlife Habitat. And I wonder how many North American suburban planned communities could be brave and generous enough to view homebuilding as an ecological mission. 

We were here to see the center but also to hear from its Executive Director, Jim Tolstrup. Originally from the Boston area, he’s been with HPEC for more than a decade, and we gathered around him in the Medicine Wheel Garden. This part of the center aligns very closely to Jim’s professional background, since he was “a founder and former president of Cankatola Tiospaye, a non-profit that provides material assistance to Native American Elders”. Though his role there, he developed life-long friendships with Native Americans and a perspective that informs much of the emphasis here at the center.

Jim told us about Centerra’s beginnings and its mission and said that the center and the community’s environmental ethos have actually become prime selling features for the development, where there are strict building and landscaping design guidelines. It’s promoted as “Certified Wild”, he said. This video is an excellent introduction to the High Plains Environmental Center.

The Medicine Wheel Garden in which we stood was erected on consecutive Earth Days in 2018 and 2019.

It will be used for the local Thompson School District’s annual 3rd grade powwow and to host participants in the 400-mile Lakota ride along Colorado’s front range each summer.

It was freshly planted with species used by various Plains tribes as food, medicine or in ceremonies. The plants are labelled with their traditional Lakota names.  Beyond the new Medicine Wheel Garden is The Wild Zone. Still being developed, it will serve as an outdoor classroom to foster a love of nature through play and self-directed learning. This section is called “The Nest Tree”.

Here is one of the plant labels in the Medicine Wheel Garden….

…. and the plant with its unripe fruit. Chokecherry fruit was traditionally mixed with pounded bison meat and tallow in the making of pemmican patties or wasna.

Here is the label for yellow monkeyflower (whose Latin genus name Mimulus has been changed to Erythranthe). Check out that clay….

And here are the beautiful blossoms. The leaves of this species were cooked by the Lakota for food.

Fishing is allowed from the shore of Houts Reservoir and adjacent Equalizer Lake, with a licence from Colorado Fish & Wildlife. The lakes also support native waterfowl.

We toured the Community Garden…..

….. where members grow tomatoes, herbs and all manner of vegetables in neatly spaced raised planter boxes. In a normal year here, there are workshops on composting, pest management, propagation and other garden practices, as well as produce-swapping potlucks.   

I wish we’d had more time to explore the Heirloom Fruit Orchard.  I was surprised to learn that this part of Colorado has a buoyant fruit industry, and that the first cherry trees were planted here in 1864. Though the trees are young, this will be a wonderful spot. Among the old varieties of apples are Haas, Goodhue, Flower of Kent, Johnny Appleseed, Utter’s Red, Patricia, Gravenstein, Maiden Blush, Pitmaston Pineapple and Duchess of Oldenburg.

The greenhouses are used to raise native plants for plant sales and landscaping. Because of Covid, this year’s sales were held online with curbside pickup. Available plants included native hyssops, sages, columbines, milkweeds, buckwheat, gaillardia, sunflowers, beebalm, tansy aster, evening primrose, penstemons, ratibidas, goldenrods, vervains and Stanley’s plume.

We walked down The Promenade, a beautiful pathway through mixed plantings of Colorado natives. Imagine how inspiring this is for Centerra residents looking for plant design ideas for their landscapes.

Honey bees were all over the apache plume (Fallugia paradoxa).  Not only is this drought-tolerant native shrub beautiful in flower, its fluffy, red seedheads are very decorative as well.

There were plants I’d never encountered before, like desert 4 o’clocks (Mirabilis multiflora).

I loved this beautiful western ninebark (Physocarpus monogyna), with Rocky Mountain penstemon at its base.  It was the perfect pairing, and the perfect way to end an all-too-short visit to the High Plains Environmental Center.

If you’re interested in First Nations culture, you might wish to read my blog on two days at Wanuskewin Heritage Park in Saskatoon, Saskatchewan, the city where I was born.

Otari-Wilton’s Bush

It’s been a while since I blogged about New Zealand and our 2018 trip, but I’ll correct that today, since there was one garden omitted – and it was my favourite. If you recall, in my last blog we were sailing back to the North Island from the South Island and settling ourselves into New Zealand’s beautiful capital city of Wellington for the final chapter of our trip. Today, I want to take you to what was my favourite public garden of our entire 3-week tour, Otari-Wilton’s Bush (whose proper name is Otari Native Botanic Garden and Wilton’s Bush Reserve, but I’ll call it OWB for short). Let’s walk from the car park through the main entrance gate or warahoa…..

….. past the Kauri Lawn and the familiar trunks of the kauri trees (Agathis australis) we’d fallen in love with a few weeks earlier on the Manginangina Kauri Walk in the Puketi Forest near Bay of Islands, on our Maori culture day.

The path leads past interesting New Zealand natives towards the information centre where we can……

….. find a map. This place is massive! There are ten kilometres of walking trails over 100 hectares (247 acres) of native podocarp-northern rata forest featuring 5 hectares of gardens containing half of New Zealand’s native plants. In total, there are.1200 species, hybrids and cultivars of indigenous plants, and we have such a short time to visit!  On that note, I should add that there was a reason why it took me so long to get this blog together: the complexity of the garden and our speed rushing through it meant that I didn’t feel I could do it justice without researching it a little more than the other public gardens we’d visited, which were more straightforward…. rose garden, perennial border, etc. There is not that kind of typical botanical garden approach here at OWB. It’s all about native plants and their conservation!  I could have spent two days there, easily

Because it’s difficult to read the map (click on it or download it for a better look), here is the legend:

The garden and surrounding bush has a complicated history, from the Maori first inhabitants – Taranaki tapū or sub-tribes – who migrated to the general area in 1821 from the Wellington region; to the arrival of European settlers in the 1840s; to the allocation of 500 acres to Maori tribes; to the 1860 purchase by Job Wilton of 108 acres for farming; to the leasing by one tribe of 200 acres to three settlers; and subsequent sales by other tribes to other settlers. By 1900, prominent citizens of Wellington began to realize that the natural land around the city was in demise. As another 134 acres of tribal land was being sold to settlers, Wellington City Council stepped in and purchased it. By 1918, Otari’s status was changed to a reserve “for Recreation purposes and for the preservation of Native Flora.” In 1926, the well-known botanist, plant explorer and ecologist Dr. Leonard Cocayne presented a proposal to create a collection of indigenous plants on the site: the Otario Native Plant Open Air Museum. He was named Honorary Botanist to the Wellington City Council and effectively Director of the Plant Museum. Over the next few years, he collected 300 native plants and published the guidelines for the development and arrangement of the museum. Upon his death in 1934, he was buried on the site.

Let’s head out over the canopy bridge spanning the ‘bush’ below.

Visitors gazing out over this scene can appreciate how this part of New Zealand looked before cities and highways were built and invasive plants outcompeted native flora.

The garden has done a good job of labelling native trees to inspire visitors to choose these for their own gardens. This is karaka (Corynocarpus laevigatus).

This is the tawa tree (Beilschmiedia tawa).

This is rewarewa (Knightia excelsa).

Looking down, you can see the exquisite structure of the silver ferns or pongas (Alsophila dealbata, formerly Cyathea).

It’s easy to see why this fern enjoys such an elevated position in New Zealand.

Interpretive signage is well done in the garden.

Though it is far away, I attempt a photo of New Zealand’s wood pigeon.

After the canopy walkway, I find myself in a section devoted to plants for the home gardener. Seven fingers or patē  (Schefflera digitata) is a small, spreading tree fond of shade and damp places. It’s the only New Zealand species in the genus Schefflera.

The Three Kings kaikomako (Pennantia baylisiana) was down to a single extant plant in New Zealand when it was discovered on a scree slope on Three Kings Island in 1945 by Professor Geoff Baylis of Otago University. Seeds were harvested, allowing it to return from the brink of extinction.

Gold-variegated karaka (Corynocarpus laevigatus ‘Picturata’) is a colorful Otari-Wilton’s Bush introduction of the evergreen New Zealand laurel tree. Its Maori name “karaka” means orange, and is the colour of the tree’s fruit.

The Leonard Cockayne centre can be booked for small meetings, workshops and education sessions.

Our American Horticultural Society tour group listens to Otari Curator-Manager Rewi Elliot giving an overview on the garden.  You can see the memorial plaque at the base of the large rock, the burial site for Leonard and Maude Cockayne.

In the adjacent Brockie Rock Garden, I find Chatham Island brass buttons (Leptinella potentillina) is a rhizomatous groundcover adapted to foot traffic.

Slender button daisy (Leptinella filiformis) is bearing its little white pompom flowers.

Purple bidibid or New Zealand burr (Acaena inermis) has become a popular groundcover plant in Northern hemisphere gardens.

Chatham Island geranium (G. traversii) has pretty pink flowers. Its easy-going nature recommends it as a good native for New Zealand gardeners.

Like a lot of shrubby veronicas, Veronica topiaria used to belong to the Hebe genus before DNA analysis. It has a compact, topiary-like nature and tiny white summer flowers.

Silver tussock grass (Poa cita) is a tough, drought-tolerant native adapted to the poorest soils.

This is a lovely view from the Cockayne Overlook.

Below, a path is flanked by some of the sedges (Carex sp.) for which New Zealand has become renowned throughout the gardening world.

We catch a glimpse of New Zealand flax (Phormium tenax) on the right along the path.

Castlepoint daisy (Brachyglottis compacta) is native to the limestone cliffs on the Wairarapa Coast of New Zealand’s North Island. Like many species here, it is considered at risk in the wild.

We had seen Marlborough rock daisy (Pachystegia insignis) at the Dunedin Botanical Garden earlier in the trip. It’s such a handsome plant.

A gardener trims the base of a sedge along the path. There are signs in the garden stating “Please do not pull out our ‘weeds’”, explaining that they may look like weeds but several are threatened endemics that are allowed to casually self-seed in the garden.

Orange tussock sedge (Carex secta), aka makuro or pukio. is common to wetlands throughout New Zealand.

Gardeners are at work trimming the sedges with the podocarp-northern rata forest in the background.

The Wellington Coastal Garden, below,  is home to native plants found on the rocky foreshores, sand dunes and scrub-coloured cliffs of Wellington. Many plants here have thick, fleshy leaves or waxy surfaces to cope with wind and salt spray.

The Rain Shadow Garden features plants native to Marlborough, Canterbury and Otago in the South Island, specifically to regions lying east of the Southern Alps where rainfall is scant. From Wikipedia:  In the South Island of New Zealand is to be found one of the most remarkable rain shadows anywhere on Earth. The Southern Alps intercept moisture coming off the Tasman Sea, precipitating about 6,300 mm (250 in) to 8,900 mm (350 in) liquid water equivalent per year and creating large glaciers. To the east of the Southern Alps, scarcely 50 km (30 mi) from the snowy peaks, yearly rainfall drops to less than 760 mm (30 in) and some areas less than 380 mm (15 in). The tussock grasslands are common in New Zealand’s rain shadow.

To northern hemisphere eyes, New Zealand has a lot of strange plants, but none tickle our fancy more than toothed or fierce lancewood (Pseudopanax ferox). You’ll see its mature tree form a little further down in our tour of the garden but I love this photo illustrating the juvenile form, often described as Doctor Seussian or like a broken umbrella.  It is now seen in gardens throughout the world, mostly owing to the 2004 Chelsea Flower Show where it starred in New Zealand’s gold-medal-winning garden exhibit.

This is my favourite image in the garden because it celebrates plants that typify the New Zealand native palette – the buff sedges and the wiry shrubs in ‘any-colour-but-green’. Save for the sword-like leaves of the cabbage palm (Cordyline australis) at the top of the picture, there is nothing ‘luxuriant’ about the plants in this garden. They evolved their sparse foliage to outsmart hungry predators or to protect themselves from wind, heat and salt.

As an illustration, here is Coprosma obconica, considered threatened in its native niche, with its “divaricating” growth habit (branching at sharp angles) when young. Note that its tender foliage is in the centre of this wiry sphere, thus protected from the nibbles of herbivores.

But then there are the big grasses and phormiums, which lend the opposite lush feeling. I love this garden, too, with its collection of flaxes, both the large New Zealand flax or harakeke (Phormium tenax) and the smaller mountain flax or wharariki (Phormium colensoi, formerly P. cookianum).  In milder climates of North America, we see P. colensoi cultivars used extensively, e.g. ‘Maori Maiden’, ‘Black Adder’, ‘Sundowner’, etc.  This is P. tenax ‘Goliath’.

A closer look at ‘Goliath’. The Māori grow harakeke plants especially for weaving and rope-making.  Note the leaves of the Carex, illustrating the mnemonic “sedges have edges”.

At the base of the steps is a beautiful stand of South Island toetoe grass (Austroderia richardii, formerly Cortaderia). It is related to the South American pampas grass (Cortaderia selloana) which has become an invasive in New Zealand (and also coastal California).

Below we see the juvenile (right) and mature (left) forms of fierce lancewood (Pseudopanax ferox) growing side by side. Note the stout trunk and the different leaves on the adult tree. Botanists theorize that the tree evolved its narrow, young form with its hooked leaves to thwart herbivory by New Zealand’s flightless bird, the giant moa, which was hunted to extinction by Polynesian settlers five hundred years ago. Once the plant reaches a certain height – around 3 metres or 9 feet in 10-15 years – it gets on with the regular business of being a tree.  The forms are so different that early taxonomists mistook them for different species.

Nearby is a garden labelled “the hybrid swarm”, featuring offspring of crossings of two other lancewood species, Pseudopanax crassifolius or horoeka and P. lessonii or houpara.

One of the tour members calls to me that she has heard the tui bird and I pass a stand of Richardson’s hibiscus (H. richardsonii)…..

…. as we go exploring into denser garden areas.

Sure enough, there it is – not the best photo, but it’s a treat to find it here. The Māori call this bird the ngā tūī, and this particular bird’s black-and-white colouration (its iridescence isn’t notable in this light) illustrates why the colonists called it the parson bird.  It is one of two extant species of honeyeaters in New Zealand, the other being the bellbird. If you read my blog on Fisherman’s Bay Garden, you might have watched the YouTube video I made of that lovely garden with the entire soundtrack comprised of the bellbird’s song.

But time is fleeting and we still have the Fernery to visit. I stop for a moment to photograph Kirk’s daisy or kohurangi (Brachyglottis kirkii var. kirkii).  It is in decline and classed as threatened, mostly due to predation from possums, deer and goats.

Common New Zealand broom (Carmichaelia australis) is not related to European broom (Cytisus scoparius), which is as invasive in New Zealand as it is throughout the temperate world.

Here is a large specimen of bog pine (Halocarpus bidwillii).

I pass a small water garden surrounded by rushes.

Crossing back over the canopy walkway, I come to the totara (Podocarpus totara) with its stringy, flaking bark. This specimen was planted in the 1930s and could live for more than 1,000 years. It is one of 5 tall trees in the Mixed Conifer-Broadleaf Forest type here; the others are kahikatea (Dacrycarpus dacrydioides), matai (Podocarpus taxifolia), rimu (Dacrydium cupressinum) and miro (Prumnopitys ferruginea).  Totara wood is strong and resistant to rot; it was used traditionally by the Māori for carving and to make their waka or canoes.  On trees 150 to 200 years old, an anti-microbial, anti-inflammatory medicinal product called totarol can be extracted from the heartwood on a regular basis. A dioecious species, female trees bear masses of fleshy, red, edible berries that the Māori collected in autumn by climbing the trees with baskets.

Now I’m on the boardwalk heading back through the Fernery to the parking lot and our bus. It was April 10, 1968 when Cyclone Giselle brought sudden winds of 275 kilometres per hour (171 mph) to Wellington, sinking the interisland ferry Wahine in sight of the harbour, with 53 lives lost of the 734 aboard. But the cyclone, the worst in New Zealand’s history, also knocked down trees throughout the country, including a swath cut through the forest at Otari-Wilton’s Bush. The opening created light favourable for the growing of ferns, and thus the fernery was launched late that year.

I see New Zealand’s iconic silver fern or ponga, which has had a botanical genus name change from Cyathea dealbata to Alsophila dealbata, courtesy of DNA sequencing.  Look at the ferns colonizing its trunk.

Later, I get a closer look at the plants climbing another silver fern, which were identified for me by an Otari botanist for my 2018 blog New Zealand – The Fernery Nation. The climbing thread fern is Icarus filiformis (formerly Blechnum filiforme) or pānoko. The broadleaf plant is scarlet rātā vine or in Māori akatawhiwhi (Metrosideros fulgens).

I pause at a few low-growing ferns, including Cunningham’s maidenhair (Adiantum cunninghamii).

…… and the rhizomatous creeping fern Asplenium lamprophyllum.

But it’s the tree ferns that are most spectacular here. Milne’s tree fern (Alsophila milnei) has also had a genus name change from Cyathea. It is endemic to Raoul Island.

Kermadec tree fern (Alsophila kermadecensis) is also native to Raoul Island.

Mamaku or black tree fern has also been moved out of Cyathea; it is now called Sphaeropteris medullaris. It can grow very tall, up to 20 metres (60 feet).

I take a quick glimpse into the native bush, which encompasses 100 hectares here as our guide calls for me to hurry. I’m the last one on the bus!

Leaving the garden, I glance back at the beautiful pou whenua carved with the creatures of the forest. Given that “Otari” is a Māori word for “place of snares” recalling its heritage as a traditional place for bird-hunting, it is fitting that it is now celebrated as a place for watching birds and all manner of wildlife and plants.

As I run for the bus, I stop to take one last photo, of the unfurling crozier, or koru in Māori, of rough tree fern or whekī (Dicksonia squarrosa).  Traditionally, the koru symbolizes perpetual movement, a return to the point of origin. It seems that the people of Wellington and those who fought to reclaim the bush for nature and education have done that here very well.

Evoking the Prairie at Chicago’s Lurie Garden

It was with great joy that I stepped into Chicago’s Lurie Garden last August. It didn’t matter that my companions numbered in the hundreds (garden communicators from all over North America at the annual Gardencomm symposium) – as long as they didn’t get in my shot!   And it was the perfect time to visit, with the Lurie evoking in a romantic, chaotic way the wildflower-spangled prairie that once stretched across sixty one percent of Illinois (21.6 million acres), before the arrival in the 1830s of homesteaders and the John Deere tractor that broke up the tallgrass sod to plant beans and barley.  No, the Lurie Garden is not a prairie recreation, and it’s certainly not ‘country’, given that it occupies five leafy acres of 24.5-acre Millennium Park in the heart of downtown, framed by some of the tallest skyscrapers in North America.

But when you see the artful tumble of some of the tallgrass prairie’s iconic natives, such as spiky rattlesnake master (Eryngium yuccifolium)….

…. and towering yellow compass plant (Silphium laciniatum), its common name alluding to the belief of pioneers that its leaves always pointed north and south,…..

…… mixed with other perennials and lush ornamental grasses in the Meadow section of the garden nearest Monroe Street, it certainly feels like walking into an August prairie in the middle of the city.

It was spring 1914 when poet Carl Sandburg wrote his ode to Chicago.
Hog Butcher for the World,
Tool Maker, Stacker of Wheat,
Player with Railroads and the Nation’s Freight Handler;
Stormy, husky, brawling,
City of the Big Shoulders

And it was the last line of that first verse and the nickname it lent Chicago – City of Big Shoulders –  that landscape architects Gustafson Guthrie Nichol lit on in the late 1990s when they conceptualized the space that would become the Lurie Garden.   Those “big shoulders” became the 15-foot high shoulder hedge, an L-shaped living wall separating the garden from the busy footpath to the Frank Gehry-designed Jay Pritzker Music Pavilion (see the steel roof angles) and Great Lawn in the space beyond.

Comprised of five cultivars of arborvitae (Thuja occidentalis) and hedge-friendly hornbeam (Carpinus betulus ‘Fastigiata’) and European beech (Fagus sylvatica), the shoulder hedge also echoes those other big shoulders of the towering skyscrapers behind Millennium Park.  By the way, that’s a cultivar of white-flowered prairie native Culver’s root (Veronicastrum virginicum) in the foreground with a purple cloud of sea lavender (Limonium latifolium) nearby.

For Dutch superstar designer Piet Oudolf, the Lurie plant design was his first commission in the U.S. and his first big public garden, though later he would design the plantings for the High Line in New York (which I blogged about in June 2014), our own entry border at the Toronto Botanical Garden (which I blogged about in March 2017 including the intricate design nuts-and-bolts) and the Delaware Botanic Gardens at Pepper Creek (opening this September), among others.  When he became the perennial plant designer of the winning Lurie design team under Seattle-based landscape architects Gustafson Guthrie Nichol Ltd. (GGN) at the turn of the millennium and had his plant list prepared, he travelled to Chicago to meet with nurseryman Roy Diblik, owner of Northwind Perennial Farm in nearby Burlington, Wisconsin.  Roy had already read Gardening with Grasses, the book Piet co-authored with Michael King in 1998, one of many design books he has written; it astonished him. As he said in a 2016 interview on The Native Plant Podcast, “It was the first book I’ve ever seen about grasses intermingled with other plants. This book showed communities, how to interplant, playfulness.  It was wonderful.”

Roy Diblik, below left, recalls their first meeting in the biographical Oudolf Hummelo – A Journey Through a Plantsman’s Life (2015 ) by Piet Oudolf and Noel Kingsbury: “I remember how he rolled out a copy of a plan for the Lurie Garden on a workbench. I could see immediately that there had never been anything like this before in the Midwest.  We went through the plants, what would work, and not work. He got me involved in producing the plants – 28,000 plants, with no substitutes. We subcontracted the growing of the easier plants and I did the more difficult ones myself.”  For his part, Piet had never seen a prairie before and Roy loved the prairie and its plants deeply, so he took his Dutch visitor to visit the Schulenberg Prairie at the Morton Arboretum, a very moving experience for Piet. So it was natural that they became more than design collaborators; they became close friends.  The professional collaboration continues today, since every two years the Lurie invites them and the landscape architects to visit the garden, inspect the plants and assess how they’re performing……

…… in a consultation that includes Director/Head Horticulturist Laura Ekasetya, below, part of the formidable all-woman team at the Lurie.

To place the Lurie in context, you can see below in this amazing July image by Devon Loerop Media the Seam, the Light Plate and Dark Plate and beyond the garden, people sitting on the Great Lawn enjoying a performance  at the Pritzker Pavilion under the airy overhead trellis containing the sound system.

Looking the other way in another image by Devon Loerop Media, you see Renzo Piano’s beautiful Modern Wing of the Chicago Art Institute, whose windows look directly onto the undulating garden, its sloping, prairie-like meadow and gardens and trees like some ever-changing work of modern art.

On a hot day last August, just beyond the bee-buzzy cloud of white calamint (Calamintha nepeta), there were young visitors cooling their feet in the water course, just out of view, that bisects the Lurie as part of the “Seam”, GGN’s evocative separation of the garden into the Light and Dark Plates. The Light Plate, left, is the sunny prairie-like side; the Dark Plate features a more garden-inspired design with many plants growing in dappled shade under black locust trees (Robinia pseudoacacia). In between on the Dark Plate side is an area called the Transition Zone, with tall plants.

The water course is part of stepped pools underlying the broad ipe wood walkway that carries visitors through the garden. But what exactly did the landscape architects intend to evoke with the Seam?  Most of the waders would not understand that this is a sophisticated means of connecting the Lurie with the underlying landscape.

Not the immense parking garage immediately below – since Millennium Park is a massive green roof, the largest in the world. Not the ghost of the old Illinois Central Railway tracks below. Rather, it evokes the swampy marshland in the delta of the Chicago River that once led into Lake Michigan just a few blocks away, atop which young Chicago grew in the early 19th century. By 1900, the river would be reversed to flow ultimately into the Mississippi River, but it was a muddy beginning for the young city that necessitated a gigantic engineering project and wooden walkways to ensure that the big-shouldered city and its citizens did not sink into the mire.  That’s the history conjured up by The Seam.

The Raising of Chicago was undertaken after outbreaks of cholera in 1854 and ’59 killed more than two thousand people. It involved the use of jackscrews to lift entire streets of buildings six feet above ground.  Below is an artist’s 1856 rendering of the plan to raise Lake Street.  Connecting historic events like this with a contemporary landscape like the Lurie is perhaps the finest interpretation of capturing a ‘sense of place’.  Read more about Gustafson Guthrie Nichol’s design rationale for the Light and Dark Plates and the Seam here.

The plants for the wildish front section of the Lurie may evoke the prairie, but Piet prefers to call this the Meadow.  As Noel Kingsburgy wrote in Oudolf Hummelo: “At the time Piet created the Lurie Garden, it represented a new level of complexity and sophistication in his design. It drew on a number of elements that had proved successful elsewhere, but it also contained several innovations. The bulk of the planting is formed of like plants clumped together, although there is a small area of innovative intermingled planting at the southern end, known as The Meadow, where species are mixed in a truly naturalistic fashion. Its matrix of ornamental grasses including the native Sporobolus heterolepis, is broken at intervals by a number of perennial species that rise up above the grasses….” The matrix system would inspire Piet a few years later in his design for the High Line. Many of the plants in the Meadow are native prairie plants, but not all. The lovely white coneflower below is Echinacea ‘Virgin’, one of Piet Oudolf’s own introductions.

Grasses are chosen for their hardiness, beauty and architectural durability, regardless of whether they’re native species, non-natives or selected cultivars.  Here is the Meadow’s matrix grass, the lovely tallgrass native prairie dropseed (Sporobolus heterolepis).

Award-winning ‘Blonde Ambition’ blue grama (Bouteloua gracilis), below, has striking pennant-like flowers and grassy, blue-gray foliage.

Autumn moor grass (Sesleria autumnalis), on the other hand, is a European grass that Piet knew well from previous designs. In June, it’s the soft, chartreuse framework for the Lurie’s spectacular purple-blue “salvia river”, and in summer, it enhances purple coneflowers and cloudlike, white-flowered prairie spurge (Euphorbia corollata).

Here is autumn moor grass nestling the tallgrass prairie forb wild petunia (Ruellia humilis).

Grasses also frame another typical prairie denizen, nodding onion (Allium cernuum).

‘Karl Foerster’ feather reed grass (Calamagrostis x acutiflora) may be the most commonly-seen ornamental grass in North America now, but it creates the perfect vertical accent below.  It is named for the renowned Germany nurseryman and plant breeder Karl Foerster (1874-1970) who in turn was the teacher of Piet’s own friend, the late nurseryman and plant breeder Ernst Pagels (1913-2007). Pagels introduced many plants we see in Oudolf gardens, including Salvia nemorosa ‘Amethyst’ ‘Blauhügel’ and other sages; Phlomis tuberosa ‘Amazone’; Veronicastrum virginicum ‘Diane; Astilbe chinensis var. taquetii ‘Purpurlanze’; and, in honour of Piet, award-winning Stachys officinalis ‘Hummelo’.

One of the paradoxes of the surge in popularity of American native plants and their selections is that much of the work was done in Germany and Holland. ‘Shenandoah’ switch grass (Panicum virgatum), below, with its rich red foliage, was selected by another of Piet’s friends, German plantsman Hans Simon. Here it is with the ferny foliage of Arkansas bluestar (Amsonia hubrichtii) and Agastache ‘Blue Fortune’, a superb hybrid of North American anise hyssop (Agastache foeniculum) and Korean Agastache rugosa, bred and selected by Gert Fortgens at Rotterdam’s Arboretum Trompenberg.

The ‘Blue Fortune’ anise hyssop was attracting hordes of monarch butterflies the day I was there, and the photographers in the crowd were vying for the perfect shot.

Pennisetum alopecuroides ‘Cassian’ is an excellent, hardy fountain grass named for Piet’s friend, Cassian Schmidt, director of the renowned German garden Hermannshof.

A signature plant in Piet’s gardens is airy sea lavender (Limonium latifolium), seen here with a tiny sprig of prairie spurge (Euphorbia corollata).

Nearby was a drift of early-blooming pale purple coneflower (Echinacea pallida), their pink flowers now bronzed with age. Seedheads and senescing plants, of course, are a vital part of the four-season design that Piet has promoted in his gardens, adding structure to plantings and an evocative, almost metaphorically human sense of “a life well lived” .  As he told a New York Times writer more than a decade ago:  “You accept death. You don’t take the plants out, because they still look good. And brown is also a color.”

The seedheads of Allium lusitanicum ‘Summer Beauty’, a Roy Diblik plant introduction, still looked wonderful, especially framing Echinacea ‘Pixie Meadowbrite’.

Wild quinine (Parthenium integrifolium) is a tallgrass prairie perennial whose flowerheads were slowly turning tawny.

Under the trees in the Dark Plate, the brown seedheads of Phlomis tuberosa ‘Amazone’ added a strong note of verticality.

Touring visitors through the Lurie, as Laura Ekasetya was doing here, often means explaining Piet’s philosophy, since people don’t always appreciate the beauty of plants once the flowers fade.   Birds do, of course, and seeds of many perennials offer nourishment to songbirds long after summer ends.

And even without their purple flowers, the tall spikes of prairie blazing star (Liatris pycnostachya) are simply spectacular, and will be prominent well into winter.

But the liatris season is long, and the knobby flowers of rough blazing star (Liatris aspera) were just opening……

….. bringing native insects to nectar. This is the two-spotted longhorn bee.

The Lurie attracts a diverse roster of insects to forage on the flowers. Native skullcap (Scutellaria incana) was being visited by a lumbering carpenter bee (Xylocopa virginica), while…..

….. tall ‘Gateway’ Joe Pye weed (Eutrochium maculatum) was entertaining monarchs, as was….

….. the ‘Diane’ Culver’s root (Veronicastrum virginicum).

In fact, monarch butterflies were even mating on the common milkweed (Asclepias syriaca) that had been left in a few spots in the garden to ensure enough food for the monarch’s larval caterpillars.

Although I’m a prairie girl at heart, I finally dragged myself away from the sunny Light Plate into the shade-dappled Dark Plate. Here, the planting is less meadow-like and more refined, much as you would find in garden borders.

And I loved the chickadees that were flitting through the trees. Here’s a little taste….

The perennials in this section appreciate richer soil and a little more moisture, too. Below is Heuchera villosa ‘Autumn Bride’ with Aruncus ‘Horatio’ having formed seedheads behind. Pink Japanese anemones are at the rear.

I could smell the perfume of the summer phlox (Phlox paniculata) even before I arrived at the spot where it was flowering.   In every possible shade of pink, it was paired perfectly with Joe Pye weed (Eutrochium spp.).

Great blue lobelia (Lobelia siphilitica) made a good companion to the phlox. Summer phlox is one of those native North American perennials that enjoyed early cosmopolitan success in the 18th century when plants were collected in the “new world” and shipped to Europe. It was John Bartram who found it growing near Pennsylvania’s Brandywine River in 1732, and sent it to England, where it soon found its way into estate borders and cottage gardens throughout Europe. Though it is occasionally susceptible to disease (and voracious groundhogs in my own Toronto garden, where I haven’t seen a bloom in years), it is such a lovely mid-late summer perennial and romantically ebullient and perfumed.

In fact, it was in this part of the garden where Piet Oudolf and Roy Diblik noticed a phlox, below, that had seeded from the original planting of a named variety.   It was clear pink and exhibited excellent characteristics.  After watching it for a few years, they had it dug up in 2016 and taken to Brent Horvath of Instrinsic Perennial Gardens (IPG) in nearby Hebron, one of the midwest’s finest wholesale perennial growers.  In honour of the Lurie’s Director and Head Horticulturist, Piet named it ‘Sweet Laura.’  And as Laura Ekasetya says, “He is including this plant in the new edition of (his book) Dream Plants for the Natural Garden.”  IPG propagated cuttings in 2017 and 2018 and it is now sold locally and at the Lurie Garden’s May plant sale.

As I was reluctantly leaving the garden to return to the symposium at the over-air-conditioned convention centre, I saw a honey bee landing on Geranium soboliferum, Japanese cranebill, belowIt cheered me up as I was planning to return on my own later that day to meet someone special at the Lurie.

IT WAS 2011 WHEN I proposed a story on urban beekeeping to Organic Gardening magazine, which has sadly since folded.  The story featured three expert beekeepers and their shared wisdom about the ancient art and science of beekeeping. One was Michael Thompson, beekeeper for the hives on the rooftop of Chicago City Hall and also the Lurie Garden.  But beekeeping (read this Edible Chicago article on Michael and his history with honey bees) and being co-founder and director of the Chicago Honey Co-op is just one of Michael’s journeys in life; he also works with urban agriculture (including an urban orchard project), especially in parts of the city where organically-grown vegetables and neighbourhood involvement are a departure from the norm. When I was making my plans to travel to Chicago, I contacted Michael to ask if there was a chance we could meet in person.  We agreed on a time and I made my way back to the Lurie that afternoon. After arriving on his bike in sweltering temperatures, Michael donned his veil and began inspecting the hives.

Brood and honey looked good for August, a product of the Lurie’s abundance of nectar- and pollen-rich plants (not to mention urban street trees throughout Grant Park and downtown).

Among the plants I’d noticed earlier with honey bees were Japanese anemones (pollen only, which bumble bees also collect)….

…. Knautia macedonica, which yields magenta-pink pollen…..

…. Culver’s root (Veronicastrum virginicum ‘Diane’), which is a superb plant for native pollinators too….

…. calamint (Nepeta calamintha), which honey bees adore…..

…. and mountain mint (Pycnanthemum muticum), which attracts honey bees and other pollinators in droves.

But apart from seeing the beehive inspection, I wanted to meet Michael in the flesh here at the Lurie, to cement one more personal connection in this wonderful world of flora that we all cherish.

And after receiving my gift of Chicago Co-op honey….

…I went back into the Lurie, now comparatively empty of people.  And I thought of the friends I was with on this symposium, people I’ve come to know in the thirty years I’ve been immersed in gardens, like Helen Battersby, who co-produces with her sister an award-winning blog called Toronto Gardens…..

…. and Washington state photographer Mark Turner, who has captured with his lens every native plant in his beautiful part of the world….

….. and Theresa Forte, who writes a column for the St. Catharine’s Standard (and is a proud grandmother like me). Behind her is Portlander Kate Bryant, who generously drove me around her fair city visiting gardens last year, not long after our Lurie visit.

I’d shared a Lurie stone wall at lunch with horticulturist Anne Marie Van Nest, a longtime friend who gardens at Niagara Parks and Quebec’s Larry Hodgson, who writes, photographs and leads tours en Français to gardens throughout the world.

I thought of the people who grow all the plants and tend all the gardens, like Intrinsic’s Brent Horvath and his partner, Chicago Botanic Garden’s Lisa Hilgenberg, who manages the edible gardens there. I would meet them at the symposium dinner later that week.

And I thought of people directly related to this very garden’s design ethos, and a fun dinner in 2016 hosted by the New Perennialist himself, Tony Spencer, standing left, with me, plantsman David Leeman, special guest Roy Diblik and nurseryman Jeff Mason of Mason House Gardens. Tony also began the Facebook group Dutch Dreams, and has become a good friend of Piet Oudolf over the years.

Those are just a few of the many hundreds of people I’ve met and become friends with in three decades. As I walked through the Meadow again, looking up at the compass plants giving the nearby skyscrapers a run for their money,……

….. I thought about spring 1999, when I’d visited Hummelo and photographed Piet Oudolf on the eve of the new millennium.  He would begin the Lurie design process just a year or so later. And of this garden, about which he said in a Tom Rossiter video recently, “The Lurie Garden created a moment in my life where I stepped over a threshold and came into another idea of design. For sure it has affected my work. And it has done a lot of good in my personal experience and it’s done a lot of good in my designs, in particular to touch people’s emotions.”

If there are big shoulders in cities, there are big shouldered people in the world of gardening and design as well.  We stand on their shoulders and learn from them, and they sometimes learn from us. It is a rarified world rendered infinitely interesting by the changing of the seasons and by the way it touches our emotions. And we are all so very fortunate to live (and work) here.

Happy 15th anniversary, Lurie Gardens and Millennium Park.
