Vertical Green Walls in Tacoma & Seattle

Leave a comment

Winter is a great time to daydream about future gardens – the garden that could be, the garden of your dreams. Soon it'll be time to prune the roses. The fruit trees are there just waiting for dormant spray and a little winter pruning and those tangled vines beckon you every time you walk by. But for now why not let your imagination go wild and consider adding a green wall to enjoy while you sit on the patio this summer?

While I was up in the Pacific Northwest over Christmas time I had the opportunity to visit two impressive green walls.  Also called living walls they got me thinking about the wall behind the patio table on my deck. It would look just awesome covered with living plants. Much of the cost of a large green wall installation is the irrigation system which allows for easy maintenance but since I'm willing to water it by hand every few days my wall will be an affordable version. First though, some inspiration.

The first wall I visited was the 20-by-40-foot living wall at the Goodwill-Milgard Work Opportunity Center in Tacoma. Designed by the the famous French inventor of modern green walls, Patrick Blanc, this wall literally dripped with plants, moss and raindrops on the day I was there.

Installed in 2009 the diagonal swaths of plants are inserted between a double layer of felt, slit to make planting pockets. Most of the soil was knocked off small 4" plants, even the woody plants. I read that Blanc used 96 different species initially but only the toughest have survived. Granted it was December when I saw the wall and some of the plants were dormant but those remaining were quite colorful and made a beautiful tapestry. Stripes of golden acorus grew beside ribbons of bergenia, artemisia, euphorbia, rubus, carex grass, Asiatic jasmine, thyme, pachysandra and vinca minor. Bands of variegated iris high up on the wall caught my eye and I marveled at the woody lily-of-the-valley shrubs and skimmia that remained small in this environment.

A drip irrigation runs across the top of the wall and in a horizontal band halfway down. Water and fertilizer drip through the felt to keep the plants perpetually moist and nourished similar to the mossy cliffs where many of these plants grow in their native environments. There's a freeze switch to stop the irrigation on the coldest days so the wall doesn't turn into a solid wall of ice.  I was told that the wall is pruned twice a year via a cherry picker.

The plan for my own living wall is to mimic the look with those Woolly Pocket planters made from recycled plastic bottles. They're the simplest and lightest to use. For clients I can suggest an outdoor wall near the kitchen planted with rosemary, oregano, thyme, parsley and other sun-loving herbs. Or in a super shady spot, the pockets could be planted with hardy houseplants like spider plant, creeping jenny, queen's tears, small ferns, wandering jew and creeping charlie. These have all survive at my house under the overhang for more years than I can count.

The second living wall I visited in Seattle covered a new building outside the new Amazon offices. This green wall is constructed from a vertical metal grid that supports square modular trays. The plants grow lush in soil pockets with micro spray irrigation providing moisture and nutrients. The effect is beautiful to look at and experience.

Winter chill made the plants pop with bright colors and glowed with deep gold, burgundy red, acid green and tawny auburn. Diagonal bands of familiar hardy plants such as carex buchanii, cotoneaster lowfast, iberis, star jasmine, Powis Castle artemisia, liriope and ferns drew my eye up, down and sideways. The wall encloses a small plaza with warm wood and concrete seating which would be inviting to sit and stay awhile on a warm day.

I'm looking forward to putting together my own green wall. I may even grow succulents in a frame in another spot.  It's an easy fun project to enhance your time outdoors and I plan to suggest this design solution whenever possible in the future.  Take the time to day dream about something new and fun for your own garden.

Chihuly Garden & Glass

Leave a comment

Recently I visited a garden of glass and it was spectacular. At the base of the Space Needle in Seattle, the newly opened Chihuly Garden and Glass Exhibit is a marriage of garden and art like no other I've ever seen. To experience larger-than-life blown glass in vibrant rainbow colors nestled among trees and shrubs was magical. I was transported beyond the ordinary to the extraordinary.

You may have seen some Dale Chihuly glass art at the DeYoung Museum when it was displayed there several years ago. Some of the pieces were influenced by Pacific Northwest American Indian art, others reminiscent of plants and sea forms. In a PBS special currently airing called Chihuly Outside, I learned that his love of blown glass has evolved since 1995 from installations in glass houses in Europe and the U.S. to massive outside exhibits in Finland, Venice, Japan, Australia and Jerusalem. The Chihuly Gardens and Glass Exhibit in Seattle is his most ambitious project ever.

Soft winter sunlight backlit the glass art that seemed to sprout up from the earth. Evergreen magnolia trees, pines and weeping cedar formed a dark green backdrop for the vivid blue, red, yellow, orange, mauve and chartreuse blown glass. Coral Bark maples echoed the same shade of glass reeds and spears. Red Twig dogwood sported a stand of fiori or flower inspired glass. Cobalt glass spheres reflected the Space Needle nearby. Swaths of steel blue eryngium or sea holly were still blooming a bit complementing the ruby glass behind.

Seattle is cold in the winter with lots of rain (sound familiar?) so plants appropriate to the site and climate are a must. Lily-of-the-Valley shrubs provide year-round interest. Their burgundy flower buds hung in clusters ready to open in the spring. Mahonia, which are native to our area also, bloomed with spikes of yellow flowers attracting hummingbirds that over winter in the area. Helleborus or Lenten Rose held tight flower buds just waiting to open. Sasanqua camellias in pink, rose and white popped with color.

Lots of burgundy coral bells carpeted the ground in front of massive logs that looked like petrified wood. I had to check for myself. Mondo grass, epimedium, strawberry  begonia and Japanese Forest grass complemented more flower inspired glass art. Strolling the garden and looking at the glass from different angles as the changing light filtered through was awesome. Chihuly doesn't so much mimic nature as borrow inspiration from it. As with all art, it's in the eye of the beholder and I fell, hook, line and sinker under its spell.

This garden of glass reminds you of frog legs with webbed toes, anemones waving in the incoming tide, towers of tall ti plants. Harmonizing plants and art is the creation of designer Richard Hartlage. Conifers, evergreen grasses, small shrubs and ferns set off the brilliant glass art. A green roof can be seen from above,a green screen of evergreen clematis encloses one side and large crape myrtles provide beautiful winter bark that blends with the lavender and burgundy glass sculptures.

A visit to the Chihuly Garden and Glass exhibit in Seattle was a day spent with light and glass and the plants that make them sparkle. I hoping to see this garden next July when the asters and rhododendrons are in bloom. Even in the quiet months of winter it was spectacular.

Ahbkazi Garden – Victoria, BC.

How many beautiful gardens can one visit on one vacation? I spent a whole day at the spectacular Butchart Gardens on Vancouver Island. a couple of hours at St. Ann's Academy heritage garden and the lovely Empress Hotel rose garden is a nice place to watch the sunset over the harbor.  But I wanted more and on the outskirts of Victoria in a residential neighborhood I found the perfect garden.

Smaller and more intimate, Abkhazi Garden offers a fine example of what you can do with a large lot full of rocks and trees if you put your mind to it. Now owned by The Land Conservancy of British Columbia, the property was bought in 1946 by Peggy Pemberton Carter who recognized the possibilities on this last undeveloped lot in the neighborhood. This independent minded woman traveled to the west coast after WW II from a prisoner of war camp in Georgia, using funds she had hidden during the war in talcum powder. She married Prince Abkhazi, a Russian fellow prisoner, when he joined her in Victoria and they began to build the summer house and lay out the garden together.

Over the next 40 years, Prince and Princess Abkhazi  designed, planted and maintained the property. Peggy had lived in Shanghai before the war and it was this influence that plays out in the garden. Chinese gardens are essentially places of meditation, places to withdraw from worldly cares. This must have been very appealing to the Abkhazi's  after their experiences in prisoner of war camps. Nothing in a Chinese garden is hurried or blatant. Paths are not just a way of getting from one point to another, instead they are a way of exploring changing views that slowly shift as you walk through the garden.

As I made my way between massive glaciated rock outcroppings and under mature native Garry oak trees gorgeous views of the snow-covered Olympic mountains and the Straight of San Juan de Fuca could be seen.
Each garden "room" utilizes the natural lay of the land and has a welcoming bench for sitting and taking in the flowers. Lots of birds and butterflies were busy feeding and going about their daily activities.

Purple allium flowers the size of grapefruit caught my attention. Growing nearby, pale yellow Candelabra primula[/caption]Japanese iris bordered one of the paths. Fragrant dianthus, several varieties of campanula and euphorbia, lady's mantle and candelabra primula were all blooming and the weeping Crimson Queen Japanese maples were pruned to perfection.

More than just a collection of plants, this garden flows with the natural contours and blends the house with it's surroundings. it is a stunning example of West Coast design. The garden flows around the rock outcroppings, taking advantage of deeper pockets of soil for conifers, Japanese maples and rhododendrons. The original Lily-of-the-Valley beds still carpet a slope. Alpine plants are placed like little jewels around the boulders and woodland plants border the undulating lawns.

A small waterfall flows into a pond where 2 large turtles sunned themselves on the rock edge while a third rested on a waterlily pad, it's red ear markings picking up the dark pink color of the waterlily flower. A stand of stately white calla lilies emerged through a piece of drifwood near a resting spot. The garden is magical. One that you could imagine on your own property if you had the next 40 years to plant and maintain it.
 
It would have been  a terrible loss if the property had not been purchased in 2000 by The Land Conservancy. After the death of the Abkhazis the land was slated to become a townhouse development. This unique garden
is truly a place of wonder. a place to meditate and to withdraw from worldly cares.

Lessons from Butchart Gardens and the Pacific Northwest

Leave a comment

I can see snow-covered Mt. Rainier from my sister's deck. Last night a rainbow bridged the Puget Sound which flows around Fox Island at the southern end of the sound. The landscape here is lush and green. Dogwoods, foxgloves and rhododendrons are still in full bloom. This temperate rain forest receives more rain than ours but I see many of the same woodland plants that we grow. I study each garden for new ideas.

The next day we head for Vancouver Island. As the clouds clear the Victoria Clipper pulls into the harbor. The Empress Hotel's landscaping is picture perfect. Purple rhododendron, hosta, and hellebore grow under the white Kousa dogwood trees. Late afternoon sun backlights each leaf. Gingko trees and weeping birch frame the Parliament building. The lights come on and outline each gable and tower. Still exploring the city later I look at my watch. It's after 10pm and still light. I forget we are closer to the land of the midnight sun at this latitude.

Visiting gardens is always the highlight of all my trips.  Butchart Gardens, a National Historic site of Canada, is a prime example of quarry restoration. Huge 100 year old poplar trees with gnarled trunks frame the famous sunken garden. Throughout the perfectly manicured lawns perennial beds grow oriental poppy, Japanese iris, Asian lily, hosta, black mondo grass, black-eyed susan, and lady's mantle. This kind of perfection comes with a price. We saw several gardeners raking and deadheading while several others cleaned around the stone border with pastry brushes.

Victoria is famous for its hanging baskets. At Butchart Gardens several hundred hand from every arbor, trellis, pergola and shepherd's hook. Mixed baskets of long blooming annuals and perennials are started early in the greenhouse then brought out in full bloom. One of my favorites featured peach-toned tuberous begonias, trailing sapphire lobelia, bacopa and coral calibrachoa. I was drawn to the dozens of hanging fuchsias and a rainbow of begonias planted with columbine, ferns and gold acorus grasses.

It must be fun to plant up the large pots that decorate the grounds. Even the wooden recycling receptacles have mixed planting on the top. Several noteworthy pots were planted with orange flowering maples paired with blue Mexican poppies and a variegated geranium. Another we liked contained a striking Electric Pink cordyline, coral petunia, calibroachoa and Bonfire begonia.

Fragrant flowers entice the senses and are planted everywhere. Strolling through the garden, vanilla scented heliotrope greet you. Spice-scented stock is planted nose high atop rock walls. Mrs. Butchart started this tradition and the garden strives to have something fragrant blooming every season of the year.

The roses were just starting to open. Many of them originated in England and Australia. The Queen's Pink peony Golden Jubilee was honored with decorative flags hung from the light posts. Flanked my tall gorgeous blue delphiniums it was quite a sight.

If it was early for the roses, the peony did not disappoint. I have never seen so many in one place. This climate is perfect for their culture. I had a hard time deciding which was my favorite. Double deep burgundy flowers grew alongside soft peach and bright pink ones. A cool white one paired well with Bridal Veil spirea. A soft peach variety looked great with the darker orange oriental poppies.

Always on the lookout for planting ideas, the endless vignettes were inspiring. The many different garden rooms in this garden allowed for countless combinations. One that caught my eye paired a purple smoke bush with coral verbascum and the variegated iris pallida. The blue flowers of the iris contrasted perfectly with the coral flowers and burgundy foliage of the other two plants.

I saw this garden in a new light on this visit. It was spectacular. Next week I'll recount my visit to Abkhazi Garden outside Victoria.

Climate change, Pacific Northwest

Gardening in Snow in the Pacific Northwest

Leave a comment

It was a snowy afternoon in the Seattle area when I attempted to ferry across the Puget Sound to Whidbey Island. Whiteout conditions got the best of us so we chickened out and decided instead to go to a local arboretum and the garden of one of my sister’s friends. While the snow came down this is what I learned about local gardening in the Pacific Northwest.

This is the home of Lily-of-the-Valley shrub and heather which are blooming now.  Crocus, Siberian iris and narcissus poked valiantly through the snow. Ornamental grasses, not yet cut back, made me think of the prairie in winter. Japanese maples of every type showed off their exquisite form cloaked with a few inches of snow.  Everywhere tall evergreen trees as well as dwarf forms anchored the landscape especially in winter.

The owner of this garden turned a weedy easement that stretched along the entire back fence line into curved planting beds created from retaining walls of beautiful dry stacked local stone. Many low water use evergreen and deciduous shrubs help this gardener in the summertime.  The Japanese maple marks where a utility pole once stood. Snow covered many of the plantings but I can just picture how pretty the spirea and viburnums will be when they bloom in spring.

We grow many of the same shrubs in our gardens as I saw in the Pacific Northwest.  Water conservation is important here, too. Although this area receives lots of winter rain and snow in the mountains by summer’s end, rivers and reservoirs in the Cascades, ground water levels and collected snowmelt reserves are gone. A little rain falls in the summer but it’s still a Mediterranean climate here. Water needs of people compete with those of migrating salmon and other wildlife and vegetation. Climatologists are predicting that climate change may mean less snow pack in the future.

Color in the wintertime is priceless even if it isn’t snowing. It’s too early for the flowering cherries but a few of the plums were starting to show color. Hellebores of every color combination imaginable were blooming in most gardens although the snow weighted down the foliage. Their  flowers stood stiffly upright like the the guards at Buckingham Palace. Bergenia flower clusters braved the weather, too. Some of our common shrubs like ceanothus, abelia, barberry, mahonia, sarcoccoca, hebe, choisya, rockrose and osmanthus are also grown here.

Later, at the in the Emerald City I was treated to fabulous gardens designed using found materials, water catchment techniques, unique paving materials and slope stabilization ideas. One large display garden featured a high mountain forest setting, complete with massive waterfall and huge boulders. A 20 foot tall Japanese maple over a 100 years old dominated one corner. They like things big in this part of the country.

Another favorite garden at the show had us wishing we could transport the whole scene to our own homes. Vintage galvanized pails and wooden flats atop repurposed shelves in a shed with windows created a cozy scene surrounded by roses growing on old wood and wire fencing. Guess you had to be there to experience it’s charm.

As I write this, snow is being forecast for our own area. Maybe it’s following me. I enjoyed my trip to the Pacific Northwest and came back with lots of new ideas but there’s no place like home.
