‘duchess of edinburgh’ clematis clematis hybrid
Here is a situation where more is better — double blooms. ‘Duchess of Edinburgh’ is a clematis with 4- to 6-in.-wide double blooms that open a light shade of green and change to creamy white as they mature. This fast-growing vine has attractive foliage, too, that’s often covered with cream-colored flecks.
Plant this regal clematis in full sun or part shade. If you grow it in full sun, keep the roots cool, either with a thick layer of mulch or by planting perennials nearby to shade the roots. Flower buds are formed on last year’s growth, so just do some light pruning after the flowers fade. You can prune the vine back hard to rejuvenate it, but don’t expect a big flower show next year because you’ll have pruned off many of the flower buds.
TYPE Perennial vine SIZE 8 to 10 ft. tall BLOOM Midspring LIGHT Full sun to part shade SOIL Moist, well-drained PESTS None serious HARDINESS Cold: USDA zones 4 to 9; Heat: AHS zones 9 to 1
