Propagation

Seed - it has a hard seedcoat and may benefit from scarification before sowing in order to speed up and improve germination. This can usually be done by pouring a small amount of nearly boiling water on the seeds (being careful not to cook them!) and then soaking them for 12 - 24 hours in warm water. By this time they should have imbibed moisture and swollen - if they have not, then carefully make a nick in the seedcoat (being careful not to damage the embryo) and soak for a further 12 hours before sowing.. Sow late winter in a warm greenhouse. The germination can be variable. Prick out the seedlings when large enough to handle and overwinter the young plants in a greenhouse for the first winter, planting out in late spring or early summer after the last expected frosts[
