Propagation

Seed - sow spring in a cold frame. The seed usually germinates within 2 months[]. 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 10 - 15cm taken at a node, mid summer in a frame. Plant out in autumn or spring. A very high percentage, they root within 3 weeks[].
Cuttings of mature wood in a sheltered outdoor bed. Good percentage[].
Layering in spring or summer. Plants often self-layer[].
