Seed - surface sow in spring in a cold frame. Do not allow the compost to become dry. Pre-chilling the seed for two weeks can improve germination rates. Germination usually takes place within 2 weeks at 20°c. When large enough to handle, prick the seedlings out into individual pots and plant them out in the summer. Basal cuttings in the spring. Harvest the shoots when they are about 10 - 15cm long with plenty of underground stem. Pot them up into individual pots and keep them in light shade in a cold frame or greenhouse until they are rooting well. Plant them out in the summer. Division in spring or autumn. Very easy, larger divisions can be planted straight into their permanent positions whist smaller clumps are best potted up and kept in a cold frame until they are growing away well.
