Propagation

• Seed - we have no information for this species but suggest sowing the seed in a greenhouse in early spring .
• When large enough to handle, prick the seedlings out into individual pots and grow the plants on for at least their first winter in a greenhouse or cold frame, planting them out in late spring or early summer, after the last expected frosts .
• Cuttings could be tried in August of half-ripe wood, preferably with a heel, in a frame .
• Stratification .
