How to Grow

Cultivation

Best grown in a sandy soil that has been enriched with humus, but any deep, moist but well-drained soil will do. Full sun is best; can tolerate partial shade but flowering is reduced; requires mild winters to flower well.

Propagation

Propagate established clumps by division in late spring.

Suggested planting locations and garden types

  • City and courtyard gardens
  • Cottage and informal garden
  • Architectural
  • Coastal
  • Flower borders and beds

Pruning

Old flower stems can be cut down after flowering and old or dead leaves tidied up or removed in mid-spring.

Pests
