List of Award of Garden Merit clematis

Over 70 species and cultivars of clematis currently (2016)[1] possess the Royal Horticultural Society's Award of Garden Merit, reflecting this plant's continued popularity in gardens in the United Kingdom. Clematis is a genus of woody based perennials, mostly climbers with a twining habit, though some are grown as groundcover or as herbaceous plants. They can be evergreen or deciduous. They bear flowers in all shades except black, pure blue, pure red and orange. The flowers are often large and showy. They can be single or double, fragrant or unscented, compact or vigorous, in a wide range of shapes and sizes. The flowering period varies from early spring to late summer. Many spring-flowering cultivars produce a second flush of blooms after the main display has finished, and many have attractive silky seed-heads prolonging the period of interest. Clematis can be grown against walls, fences, over pergolas and obelisks, or through other shrubs and trees.[2]
