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. Good drainage in winter is essential. Full sun is best; can tolerate partial shade but flowering is reduced
Propagation
Propagate by division of established clumps in late spring. Propagate by taking offshoots from the crown
Suggested planting locations and garden types
- Cottage and informal garden
- City and courtyard gardens
- Coastal
- Flower borders and beds
Pruning
Old flower stems can be cut down after flowering. Trim back old winter damaged foliage in spring
Pests
Can be damaged by slugs and snails. Thrips may cause mottling of the foliage
Diseases
Generally disease free, if winter drainage is good. Violet root rot may be a problem
