Propagation

Seed - Germination can be slow, sometimes taking more than 18 months.
Stored seed will require 2 months warm then 3 months cold stratification and can still take 18 months to germinate. Prick out the seedlings into individual pots when they are large enough to handle and grow them in a greenhouse.
Plant out into their permanent positions in late spring or early summer of the following year.
Cuttings of soft-wood, early summer and pot up into individual pots once they start to root and plant them out in late spring or early summer of the following year.

Cuttings of half-ripe wood, 12 - 15 cm (6 in) long with a heel if possible, July/August in a frame.
Plant them into individual pots as soon as they start to root.
These cuttings can be difficult to overwinter, it is best to keep them in a greenhouse or cold frame until the following spring before planting them out.
They should root in early spring - pot them up when large enough to handle and plant them out in the summer.
