How to grow

Cultivation

Best grown in moisture retentive well-drained soil that does not dry out in summer, in full sun or part shade. Excessive vigour in moist soils can make it a determined spreader, so has the potential to become a nuisance if not managed well

Propagation

Divide vigorous clumps in spring or autumn

Suggested planting locations and garden types
  • Cottage and informal garden
  • Flower borders and beds

Pests

May be damaged by slugs and snails
