Great Clematis for the Pacific Northwest
Regional Gardening, Best Clematis, Pacific Northwest Gardening
To see a clematis in full bloom is to understand why it is called the queen of flowering vines. As climbers, Clematis are unsurpassed in their long flowering presence, their rich diversity of flower shapes, their wide array of colors and tolerances in terms of exposure and climate. It is no wonder they are so popular! From tree huggers to container varieties, there is a Clematis for every garden and flowers for almost every month of the year!
Members of the Ranunculaceae family, they include more than 300 species and hundreds of hybrids. They create year after year a ravishing colorful show in the garden whether solely trained on walls, arbors or trellises, or grown in association with other climbers. With few demands on the gardener, clematis will reward you with a profusion of gorgeous blossoms. Clematis are divided into 3 groups based on bloom times, flowering habits and pruning requirements.
But which clematis will you choose?
Here is a list of clematis cultivars and varieties that will reward Pacific Northwest gardeners with exceptional floral displays, provided you respect their cultural conditions and site placement:
- Ideally, Clematis prefer having their 'heads in the sun and their feet in the shade'. Keep the roots cool and shaded by other plants or add a layer of pebbles or flat stones at the base.
- Best floral performance and disease resistance is usually seen in south-facing positions.
Great Clematis for the Pacific Northwest
Clematis 'Apple Blossom' (Evergreen Group)
One of the most popular evergreen clematis, award-winning Clematis 'Apple Blossom' is a very large climber with masses of delightful, almond-scented flowers, 2 in. across (5 cm), and a splendid foliage. Opening from nearly red buds, the single flowers gradually fade from pale pink to white as they mature. If the weather remains cool, flowering persists for 2 to 4 weeks. Equally attractive, the foliage of leathery, waxy, evergreen leaves emerges bronze-tinged before turning mid-green. Rattling in the wind, the heavy leaves overlap nicely and form a lovely screen year-round. Clematis 'Apple Blossom' blooms profusely from early to mid-spring. Vigorous and quick-growing, this early-flowering clematis is perfect for covering a wall, trellis, fence, or pergola.
