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

Propagation

Propagate by division in spring.

Suggested planting locations and garden types
  • Cottage and informal garden
  • Flower borders and beds
  • Underplanting of roses and shrubs
Pruning

Treat more like a herbaceous perennial, taking all stems to ground level in autumn or just before growth starts in spring

Pests

Young shoots may be troubled by aphids and caterpillars; petals can be eaten by earwigs

Diseases

May suffer from clematis slime flux
