Clematis 'Jackmanii'

Location:

Autumn Border

Description:

A hardy large-flowered, late-flowering clematis. The rich dark purple flowers are like velvet, and make are a wonderful sight, clothing walls from mid to late summer.

Site and Care:

Plant in a moisture-retentive, well-drained soil, with the roots in shade and the stems, leaves and flowers in sun or partial sun. Plant the crown 5-7.5cm (2-3in) deep to encourage shoots to grow from below ground level. Keep the base shaded and cool. 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. Propagate by layering or semi-hardwood cuttings.
