CultivationFertile, 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 later in spring. Plant tubers 15cm deep in winter or early spring. Apply a deep winter mulch in colder areas
PruningDeadhead after flowering
PropagationPropagate by division of tubers in spring when growth is starting
Pest resistanceSlugs and vine weevil may be a problem
Disease resistanceMay be susceptible to a virus
