Propagation
Lift and divide the clump during late summer and replant immediately into a prepared bed. Remove offsets as required.

Plants bulbs up to 50 mm (2in) deep and 100 mm (4in) apart during early autumn.  Leave undisturbed and divide only when they become congested.

Sow fresh seeds during autumn and flowers appear within four years.

Culture
The soil must be kept moist and the plant responds to organic mulch. Fertilising is not normally required, though the addition of blood and bone to the soil during the growing period will encourage vigour.

Note:
Care should be taken as all parts of the plant cause skin irritations.
