How to grow

Cultivation

Plant in a moisture-retentive, well-drained soil. Keep the base of the plant and roots cool and shaded by other plants or a layer of pebbles or flat stones at the base. Plant with the crown of the clematis at soil level. Mulch in late winter with garden compost or well-rotted manure, avoiding the immediate crown. Ideal for a border where it can be supported by other plants or useful groundcover. See clematis cultivation for more advice

Divide or take basal cuttings of this semi-herbaceous species in spring or semi-ripe cuttings in early summer
