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 valian
tly 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.
will improve the environment by conserving resources. It will require less maintenance and fertilizing, be balanced with our climate in mind and use less pesticides and water. Most of all it will be visually pleasing with lots of flowers. bees and butterflies. 
When do they occur each year? Phenology is a real science that has many applications. In farming and gardening, phenology is used chiefly for planting times and pest control. Certain plants give a cue, by blooming or leafing out, that it’s time for certain activities, such as sowing particular crops or insect emergence and pest control. Often the common denominator is the temperature.
