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
Propagate by division in early spring when clumps become congested or Propagate by seed sown in containers in a cold frame as soon as ripe
No pruning required, except the removal of dead leaves and flower stems before new growth starts in spring.
May be susceptible to glasshouse red spider mite
Generally disease-free
