How to Grow

Cultivation

Grows best in deep, cool, moisture-retentive soil in partial shade, but will also tolerate most soils and full sun if soil is humus-rich and protected with mulch to ensure that it is moist throughout the growing season; use protective gloves

Propagation

Propagate by division in autumn or late winter; division every few years may encourage good flowering stems, though plants may be slow to re-establish; use protective gloves

Suggested planting locations and garden types

  • City and courtyard gardens
  • Cottage and informal garden
  • Wildlife gardens
  • Climber and wall shrubs
  • Flower borders and beds

Pruning

No pruning required but deadhead spent flowers. Cut back dead stems to ground level in autumn and before the new growth emerges in spring

Pests

Generally pest-free but may be susceptible to aphids

Diseases

May be susceptible to fungal stem rot, powdery mildews, and Verticillium wilt
