How to Grow

Cultivation

Grows best in a moist, humus-rich soil in sun or partial shade at the back of the border as a backdrop for other perennials. May require staking, particularly in windy or wetter areas. Protect from strong winds. See staking perennials for further advice

Propagation

Propagate by division every 3 to 4 years in spring as new growth begins

Suggested planting locations and garden types

  • City and courtyard gardens
  • Cottage and informal garden
  • Flower borders and beds
  • Wall side borders

Pruning

Faded flower stems can be cut back in late autumn or in spring before new growth starts emerging. Cutting back will also prevent self-seeding if this is not required

Pests

May be susceptible to slugs

Diseases

May be susceptible to powdery mildews in dry conditions
