Plant details

Raised in 1874, 'Ascotiensis' stills holds own among modern varieties. A perfect partner to red roses, it produces mid-blue flowers from mid-summer to early autumn. As with all the late-flowering clematis, pruning is easy. Simply cut back the stems to a pair of strong buds 15cm to 20cm (6in to 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.
