Propagation

Seed - pre-soaking the seed for 24 hours in warm water may reduce the germination time. Sow in containers in a lightly shaded position. The seed usually germinates within 1 - 12 months if kept at a temperature of 20°c. Prick out the seedlings into individual pots when they are large enough to handle and grow them on until large enough to plant out.
Root cuttings. Lift the plant and remove small buds from the base of the stem and rhizomes. Dip in dry wood ashes to stop any bleeding and plant in a sandy soil in pots until established[
