Propagation

Seed - we have no information on this species but suggest sowing it in early spring in a cold frame. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Division of rooted runners. Probably best done in spring but can be done at any time in the growing season if the plants are kept moist.
