Propagation

Seed - not often produced.
Division of established clumps. This is best done annually or they can become too crowded and suffer, commercially the plant is divided every 4 - 6 years. The size of offshoots used depends on local preference; larger shoots normally root quicker and grow faster. The offshoots are cut back to 10 - 15 cm, trimmed of dead and excess roots and then planted either direct or into nursery beds[
