Propagation

Seed - cold stratify for 4 weeks at 4°c[] and surface sow the seed in late winter/early spring in a greenhouse[, ] (the pre-chilling might not be required for this species). Germination usually takes place within 3 - 4 weeks at 21°c[]. When large enough to handle, prick the seedlings out into individual pots and grow them on in the greenhouse for at least their first winter, planting them out into their permanent positions in late spring or early summer, after the last expected frosts. Seedlings are inclined to damp off and so should be watered with care and kept well-ventilated[].
Cuttings of half-ripe wood, mid summer in a frame[, ]. Use short side-shoots[]. Very high percentage[].
Cuttings of mature wood of the current season's growth, 15 - 20cm long, autumn in a frame[].
