Clematis 'Kermesina'

Plant details

Raised in France in 1883, 'Kermesina' produces rich red flowers from mid-summer to early autumn. Some of the flowers early in the season may have green tips. It is a member of the viticella group of clematis and as such it shows good resistance to clematis wilt. As with all the late-flowering clematis, pruning is easy. Simply cut back the stems to a pair of strong buds 15-20cm (6-8in) above ground level before growth begins in early spring. This pruning technique makes late-flowering clematis useful for training into shrubs, trees and climbing roses as the clematis growth is removed each spring and so never becomes too much of a burden on its supporting plant.
