Propagation

Seed - best sown outdoors, or in a cold frame, as soon as it is ripe[5]. Stratify stored seed for 3 weeks at 1°c and sow in spring[5]. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in a cold frame for at least their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts.

Softwood cuttings, 10cm long, in a frame. They should be taken in late spring to early summer before the leaves are fully developed[5].

Root cuttings in winter[5].
