How to grow
Cultivation
Corms should be planted in moderately fertile, humus rich soil approximately 10cm deep and 7.5–10cm apart in groups to form clumps. Water if it is a dry season as a lack of water reduces flowering. Has the potential to become a nuisance in some gardens if not managed well.
Propagation
Propagate by division in early spring when clumps become congested. As this plant is protected by Plant Breeders' Rights, any propagation should be for personal rather than commercial use
