Plant Propagation
Seed - best sown as soon as it is ripe in a cold frame. The seed can be very slow to germinate, stored seed requires 5 months warm then 3 months cold stratification at 5°c[200]. 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 half-ripe wood, 3cm with a heel, July/August in a frame. Takes 3 weeks. Good percentage[78, 200]. Cuttings of mature wood of the current year's growth, 3cm with a heel, October in a frame. Requires shade. Good percentage[78, 200].
