Propagation

Seed - we have no details for this species but suggest sowing the seed as soon as it is ripe in a greenhouse. Only just cover the seed and place the pot in 3cm of water to keep the soil wet. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.
Division. Harvest the tubers at the end of the growing season, store them in a cool but frost-free place over the winter and plant them out in early spring.
