How to Grow

Cultivation

Ideally this should be grown in soil that is moist but well-drained in summer and well-drained over winter; this provides the fleshy roots with moisture in summer yet allows it to overwinter. Full sun is essential

Propagation

Propagate by seed sown in pots in a cold frame in spring or autumn or propagate by division in spring

Suggested planting locations and garden types

Cottage and informal garden
Cut flowers
Flower borders and beds

Pruning

Seed spikes are attractive and can be left, but cut them back if you want to prevent self-seeding

Pests

May be susceptible to slugs and snails

Diseases

Generally disease-free
