Royal Horticultural Society Award of Garden Merit
Clematis 'Comtesse de Bouchard' is a showy, perennial, large-flowered clematis offering early to late summer interest. A gardeners' favorite since the early 1900s, the extremely floriferous plant sets masses of large, shell pink flowers with a touch of lavender and contrasting creamy yellow stamens in the center. The single, 6-petaled flowers have wavy-edged, recurved petals that give the blooms a rounded shape. The plant blooms on new wood, and at maturity, the vine is fully covered in flowers that attract bees, butterflies, and hummingbirds.
A fast-growing, deciduous climbing vine, Clematis 'Comtesse de Bouchard' has a compact, twining, and trailing growth habit of bright green leaves that stay fresh and attractive all season. There is an old saying about clematis' growth rate: The first year they sleep, the second year they creep, and the third year they leap. Train clematis to climb a trellis, arbor, post, or fence, adding vertical interest. Or allow it to amble along the ground, meandering gracefully through the shrubbery. But for something really special, pair it with a climbing rose, allowing the nimble clematis to twine its way around the sturdy rose stalks. The two will elegantly mingle blooms in the early season, but the clematis will carry it through the heat of summer and the rose will pick up again in fall as the clematis' blooms fade.
Cold Hardy, easy to grow, and less prone to clematis wilt than other large-flowered varieties, Clematis 'Comtesse de Bouchard' prefers full sun to part shade and fertile, moist, well-drained alkaline soil. But it tolerates a wide variety of soils, including chalk, clay, and loams that are acid or alkaline. Good site selection is key. So, remember the adage for success with clematis when planting: feet in the shade, head in the sun. The plant should be placed where the leaves get plenty of sunshine (approx. 6 hours), but the roots are shaded and kept cool, either by low-growing, evergreen shrubs or by heavy mulch. Good drainage is important, and extremely wet locations should be avoided. Protect the vine from strong winds but allow good air circulation. Deer resistant.
A Group 3 late-flowering clematis (blooms on new wood in the summer and fall; dies to the ground over winter), Clematis 'Comtesse de Bouchard' should be pruned hard before new growth appears in late winter to remove dead or weak, spindly stems and to make way for the new growth. Cut back to 2 feet or just above pairs of healthy, swelling leaf buds. If training to climb, loosely tie the vines to their structure at this time. It can be pruned again after the first flush of flowers in early summer, cutting back to large buds, to promote a second flush of flowers, but deadheading is unnecessary. This group has to re-grow to their mature size each summer, so they tend to be the last to flower.
