Lessons from Butchart Gardens and the Pacific Northwest

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.

Hidden Gardens of Bonny Doon

Enter the Hidden Gardens of Bonny Doon with me as I preview several gardens that will be featured on the tour this coming weekend.  While some of our gardens have a few areas with a "wow factor" , the gardens I was privileged to visit have this element at every turn. I was amazed, impressed and truly honored to spend time in each of them.

First stop was a garden that took my breath away. Looking past the lush lawn, the view takes in all of Monterey Bay. It wasn't always this way, the owner explained. When she moved to the property in 1981, she didn't even know there was an ocean view. It was only after some judicious pruning that this stunning view was revealed.

We  ambled through the many paths that took us up close and personal with perennial beds overflowing with blooming iris, spirea, weigela, succulents, hardy geraniums, coprosma and coleonema to name just a few.

Rabbits are an ongoing problem in this garden. Seems they love her Angelina sedum, coprosma, and Rose Campion as much as she does. Little 12" tall fences surround several of the beds which looks comical but apparently works as the rabbits don't like to jump over them.

Stained urbanite has been stacked by the owner to make short retaining walls and the look is quite classy blending in the flagstone and gravel paths. She explained how easy it was to stain the broken concrete from the old driveway by slapping on some concrete stain. "Piece of cake", she told me.

Other flower beds she edged with Sonoma fieldstone, stacking them herself. At every turn you can see the personal touches that make a garden unique. An old rusty mailbox was tucked into one of the beds overflowing with blooming pansies and million bells calibrachoa.  I loved this garden.

Next stop was another garden 30 years in the making. You won't believe the "before" pictures when you see this garden now. I could barely see the potential in the old pictures but the owner could and started to build up the rock hard soil bed by bed. After many years she has created  an organic garden full of flowering rhododendron, roses, viburnum, herbs, vegetables, citrus, apples and a 5 year old  Staghorn fern that measures 4 ft across.

The owner explained that deer are not a problem because they won't jump the irregular picket fence. Seems the wide pickets confuse their eyesight. Unfortunately, the gophers have decided recently that after 14 years, her camellias are now on the menu and she has lost almost all of the original 40 in the past year. Instead of lamenting her loss, she sees it as an opportunity to add new plants. She has the optimism that all gardeners possess.

Chickadees nested in a box attached to the porch. Garter snakes and alligator lizards patrol the flower beds. A bathtub, sunk into the earth serves as "the poor man's hot tub". Old metal chairs are planted with flowers and ferns and other found garden art is sprinkled generously though out the garden. This is the garden of an artist whose studio is nestled back among the trees. At every turn you feel the peacefulness of this wonderful place. This is a garden to experience not just view.

The last garden I was lucky enough to preview, was an asphalt driveway just 6 short years ago. There are occasional unplanted spots that still show asphalt. What a transformation. With the help of lots of top soil and an auger this gardener has created a spectacular space.  "Everything grows like crazy here", she explained.

The front garden is open to deer and is planted with echium, leucospermum, arctotis, barberry, thyme, rosemary and New Zealand flax. One of her favorite plants is a huge variegated holly that buzzed so loudly with bees I thought the electrical line coming into the house was making all the racket.

In the back, a small orchard edged the fence. Blooming lilacs by the deck heavily scented the air. Succulents intermingle with peony, erysimum and gaura. This gardener explained she " she is one of those people who buys whatever she likes and then finds a place for it". Having had previous experience growing grapes and olives in Sonoma, she is a hands-on gardener who does it all herself. She's a self-described  "drip queen".

A ceramic artist, her sculptures are focal points though out the garden. There is a lot of other garden art in this garden, too.

Where do these gardeners find the garden art, water features and other items that give their gardens that personal touch? One explained, she is always on the lookout for estate sales as she drives around or sees advertised in the paper. "That's were you can really find the treasures", she explained. "Little old ladies have some great plants and other wonderful finds in the back of the garden".

The Hidden Gardens of Bonny Doon Tour takes place Saturday and Sunday, May 19th and 20th. Don't miss it.
 

Terra Sole Nursery Trials New Plants

Have you ever wondered what it would be like to start your own little nursery on your property? What would you grow? How would you decide?  Over the years, I've been asked by home owners with a bit of extra property what would be good to grow. What is there a market for? So I decided to ask some friends who trial plants on their Watsonville property and operate a small nursery there how it all works.

Terra Sole Nurseries was founded in 2004 by John and Sherry Hall with the goal of experimenting and growing native, unusual and drought tolerant plants that are adapted to our dry summer climate. "We push the limits on water use in our test garden until we fall too much in love with a plant and can't bear to see it die with our tough love approach", Sherry said as we talked about the their operation.

Just back from attending the California Spring Trials,  Sherry and John were excited to share how they decide what to grow In their nursery. Their focus is to grow a large variety of native and unusual plants, some of which are old-fashioned, some are hot new introductions. What treasures did they find this year?

During the course of a week at the Spring Trials,  the world's prominent plant breeders, propagation specialists, growers, marketing professionals and plant enthusiasts share the latest and greatest at several open houses throughout California. The robust plant varieties of today are a direct result of the countless hours and decades of study from the dedicated professionals spending their time observing, testing and experimenting the new varieties that are more disease resistant, more floriferous, the best performers and are easy to grow in ordinary landscapes and gardens.  

How does a plant get from an idea in a breeder's mind to your local nursery? It all starts with the breeders who might cross pollinate thousands of plants to select maybe a hundred of the best ones. Then the growers buy an unrooted cutting or the seed or plugs of rooted plants and grow them onto a larger size. This is where the finish growers buy the plugs and liners to put into bigger pots growing them to retail or sellable size. Terra Sole Nurseries bought some of the newest plants on the market this year themselves.

What are some of the newest trends that we might see in our neighborhood nursery this year? The breeders of impatiens have developed a variety that appears to have a gingerbread man in the center. Called Patchwork this  impatien has a bigger flower and comes in six bi-colors.

Grafted vegetables, higher in antioxidants, are being developed. Non GMO vegetable varieties are grafted onto vigorous rootstalks to produce a plant disease resistant higher in nutrients. Tomatoes, basil, cucumbers. peppers and lettuce are just some of the vegetables being grown.

Biodegradable pots made from wheat are another of the new trends being offered for sale at the Spring Trials. The pots look like plastic yet breakdown after being used and can be recycled in your compost system. They hold up to the normal environmental pressures of heat, water and cold.

Sunset Western Gardening and HGTV are both offering their own branded plants that are available this year. Patented varieties coming out include a compact hardenbergia called Meena, two upright. compact nandinas- Flirt and Obsessive with bright red winter color and a compact mahonia called Soft Caress with non-prickly foliage. A cold hardy salvia named Amistad that has a very long bloom time will also be coming out soon.

To simplify choices for gardeners, better dahlias, calibrachoa, petunias and pansies are coming on the market this season. Several types are grown in the same pot so the buyer need only to plant one of these in a basket or container to get a combination that will look good and grow happily all season.

With so many plant choices which ones do Terra Sole Nurseries trial in their own garden and grow in their nursery? Next week I'll talk about what Sherry and John have their eye on, which plants they grow and the results of their own plant trials. You can find out more about the nursery at www.terrasolenurseries.com.

Early Spring Flowering Plants

 I look out my window and see deep pink ruffled flowers covering my Blireiana flowering plum.   It's one of my favorite early spring blooming plants and those fragrant blossoms are strong enough to scent my garden. It grows next to an Autumnalis flowering cherry that blooms nearly every month of the year. I'm not kidding. It's the energizer bunny of the flowering tree world.  We all look forward to the earliest flowers of the new season.  What else blooms in winter that you might want to have in your garden? Here are just a few suggestions.

One old fashioned shrub that figured prominently in many old gardens is forsythia. Deep golden-yellow flowers completely cover the bare stems in late winter and become the focal point of the landscape when in full bloom. The showy stems of this easy care shrub are great for cutting. Forsythias are native to eastern Asia but a chance discovery in Germany by a grower who specialized in breeding for the cut flower industry led to the especially vivid variety Kolgold in the 1800's. Forsythia has long been used in Chinese medicine. The flower petals contain powerful bacteria-fighting properties which make it an important dressing.

Hellebores are another winter blooming plant that with foliage that looks great, too. My double purple one has been blooming for well over a month now. I've got my eye on a variety called Golden Sunrise. Each plant is  different with variations of large, canary yellow flowers. Some are solid yellow but most have some degree of red veining and a red picotee edge. Some have a red starburst in the center. Hellebores bloom for six weeks or more and are deer and rabbit resistant. They are often flowering during the Christian season of Lent from which they get their common name, Lenten Rose. Use them for naturalizing in woodland areas. They are a low maintenance plant, will survive with little water and are disease and pest free.

What would a shade garden be without a bright orange clivia? Every year I look forward to their huge flower clusters to emerge from the dark green strappy leaves. Even in dark shade they will bloom and brighten the winter garden although they would do fine in morning sun. If you have a north facing window you can grow them as houseplants. Clivias are hardy to several degrees below freezing but mine, under an overhang, have survived temps of 23 degrees without damage.

Clivia breeders have produced gold and peach colored flowers also but I still like the standard orange and they didn't cost $599 like the plants I saw offered on the internet. I thought this price might have been a misprint but on further investigation I found another site offering the yellow Gloria clivia for a mere $950. I'll stick with my orange ones.

A beautiful vine that blooms in winter is Hardenbergia 'Happy Wanderer'. In the pea family, this evergreen vine looks like a small wisteria when in bloom.  Pinkish purple flowers cascade in clusters on twining stems that reach 12-16 feet long. It requires little water once established and is hardy to about 23 degrees. If you have an older, tangled plant you can rejuvenate it with hard pruning in early spring after flowering. Never prune in late summer or fall because you will cut off the wood that is going to bloom the following winter.

The last plant I couldn't live without is Fragrant Sarcococca.   The tiny flowers of this plant are easily overlooked but you can't miss their scent. If you have a problem spot in dry, deep shade give this plant a try. It's easy to grow, deer resistant and trouble free.

Fragrant Roses & How to Prune Them

I'm daydreaming about the flowers of spring and summer and what could be more impressive than a big, fragrant, jewel-toned rose? There are some great new ones out this year that I have my eye on. Maybe you have room for one more.

Fragrance is a requirement for me when it comes to roses. First thing when we admire a beautiful rose is to bend over and smell it. Sure vase life and petal count are important but who can resist a fragrant rose? With that in mind, several of the new varieties out this year fit my bill. Consider one of these for your garden.

Orchid Romance is a small, medium pink to lavender floribunda rose. It has a strong citrus aroma on warm days. Grown on its own root it has good disease resistance and holds up well in a bouquet. Medium large, very full flower clusters bloom in flushes throughout the season.

Sugar Moon is an elegant pure white rose with huge, full, classically formed buds. Saturated with an intensely sweet citrus and rose fragrance the scent is said to nearly bowl you over. Long cutting stems makes this a perfect addition for the cutting garden. Superior disease resistance is another plus for this new rose.

Cold weather earlier this month has kept roses in the garden dormant but now is the time to prune them before they start leafing out which wastes plant energy. I want them to produce lots of roses on a compact shrub not just a few exhibition size so I prune shrubs moderately.  Heirlooms, however, require less pruning because their open look is part of their charm.  Remember your goal is to keep the center of the plant open for good air circulation.  Aim for a vase-shaped bush with an open center by cutting out crossing canes, spindly, weak, broken or diseased stems as well as dead wood. Cut back the remaining stems by about one-third, cutting canes at a 45-degree angle, just above an outward facing bud.

Don't worry whether you're pruning job is perfect. Roses are super forgiving and you can trim them up again later. I once helped prune the rose garden at historic Gamble Gardens in Palo Alto. To revitalize the old shrubs we sawed out most of the beefy canes. I didn't think they could recover in time for the big May bloom but they did and were spectacular. Roses are like redwoods -you can't kill one- they're the energizer bunnies of the plant world.

Climbing roses require little pruning. Cut out extra stems if there are too many and also cut back long established canes to where they are slightly thicker than a pencil. Then cut each side stem down to several inches. This will cause the cane to flower along its complete length for a beautiful spring display.

Remove any leaves that may still be clinging to the bush. Rake up debris beneath the plant and discard to eliminate overwintering fungus spores. It's a good idea to spray the bare plant and the surrounding soil with a combination organic horticultural oil to smother overwintering insect eggs and a dormant spray like lime-sulfur to kill fungus spores. If you usually only have problems with black spot you can use a mixture of 1 teaspoon baking soda with a few drops of light oil in 1 quart water and spraying every 7 to 10 days.

And that's all there is to it. Email me if you have any questions.
 

A Private Arboretum in the Santa Cruz Mountains

Recently I had the honor to tour a remarkable garden in Scotts Valley. This horticulturalist calls himself a hillbilly gardener but he is no such thing. Some of his plants come from as far away as Oklahoma, Texas and Hawaii. What a thrill to see spring growth emerge from the new leaves of his unusual trees, flowering shrubs and perennials.

Our first stop was to admire his large collection of echium candicans or Pride of Madeira. These stately shrubs reach 5-6 ft tall and 6-10 ft wide so they make quite a show when the huge flower clusters are in full bloom. Being deer resistant and drought tolerant they are perfect for our mountain environment. The color of the spikes varied from pink to lilac, sapphire blue and purple. This gardener is resourceful. He got many of his seedlings along Hwy 17 where they had reseeded after being used as brush to stabilize the slopes after the ’89 earthquake. The bees were really happy visiting the hundreds of blossoms on the beautiful spring day that I was there.

Tucked under wild cherry trees collected in Texas, are second generation iris of dark purple and pure yellow. Originally from his grandmother’s garden in Virginia, these iris are descendants from a light blue variety and a pale yellowish-beige douglas iris.

This extraordinary gardener also has a huge wild rose from Missouri covered now with fragrant white flowers, a wild olive from Texas and a sand plum from Oklahoma.  There is a yucca about 4 ft tall that he and his brother started as cuttings when they were teenagers in Port Arthur, Texas. He is also the proud father of a couple of bald cypress complete with "knees". This tree of southern swamps and other low nutrient areas grows woody projections above the ground or water level to act as a structural support and stabilizer allowing them to resist very strong winds. Even hurricanes rarely overturn them.

A beautiful Canary Island palm, planted from a seedling in 1996 that he had nurtured in a gallon can, is now over 9 ft tall.  Akebia vines grow up oak trees, passiflora and white wisteria vines up redwoods, a yellow banksia rose rambles up into a madrone and madevillea laxa is happy growing up an oak, too. A willow-leafed hakea salicifolia, indigenous to New South Wales and Queensland, graces his entry with its tiny, white fragrant flowers.

Other trees this gardener loves include Causarina, native also to Australia, sugar pine, incense cedar, Western red cedar, deodar cedar, staghorn sumac and a maytens tree.  His mother in Pennsylvania taught him to plant his first garden at age 4 and he cherishes his Eastern white pines, pinus stroblis, and giant sequoias, three of which he grew from seed.

And I can’t forget his collection of salvias. The red flowers spike of salvia confertiflora bloom year round. The beautiful salvia mexicana will soon to be covered with rich, blue flowers. He also grows salvia chiapensis and a salvia-like plant native to Hawaii called salvia lepechinia. This deliciously scented plant will be covered soon with reddish lavender lipstick-like flowers adored by hummingbirds like all the salvias.

A new greenhouse where he has a small collection of orchids will soon house new seedlings that are sprouting in a germination station under lights. Of the many Hawaiian seeds he has collected are maile, a flowering plant that is probably the oldest and most popular material used in leis by early Hawaiians, milo- a chocolate and malt powder popular in many parts of the world, gossypium tomentosum, coral vines, hibiscus and the koa tree.

There were hundreds more cool plants I learned about and got to admire that day. I’ll be visiting this garden again and again for the next round of wonders. it’s a marvel.
