Propagation
Seed - we have no information for this species but suggest sowing the seed in spring in a greenhouse. 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. Cuttings of softwood in late spring in a frame. Cuttings of half-ripe wood, 7cm long with a heel, July/August in a cold frame.
