How to Grow

Cultivation

Grow in moist but well-drained humus-rich soil in light dappled shade, for example in a mixed bed or an open woodland garden, or in full sun, and add organic mulch. See foxglove cultivation for further advice

Propagation

Propagate by seed, sown in spring; it is sterile so will not self-seed

Suggested planting locations and garden types

  • Cottage and informal garden
  • City and courtyard gardens
  • Wildlife gardens
  • Cut flowers
  • Flower borders and beds

Pruning

No pruning required, but deadheading, cutting down dead flowering stems, will encourage a longer flowering season and encourage growth the following year

Pests

May be susceptible to aphids and leaf and bud eelworm

Diseases

May be susceptible to powdery mildews, downy mildews and leaf spot
