How to Grow

Cultivation

Fertile, humus-rich, leafy, moist but well-drained neutral soil is preferred; although best in part-shade, if the soil is moist will do well in more open sites. Young growth is late, often not appearing until early summer. Plant tubers 15cm deep in winter or early spring. Apply a deep winter mulch in colder areas, and take pots under cover

Propagation

Propagate by seed in containers in a cold frame as soon as ripe or by division in spring

Suggested planting locations and garden types

  • Patio and container plants
  • Cottage and informal garden
  • Flower borders and beds

Pruning

Deadhead after flowering

Pests

Slugs and vine weevil may be a problem

Diseases

Generally disease-free, but may be susceptible to a virus
