How it is grown
Succeeds in any fertile well-drained moisture retentive soil in full sun or light part day shade. The young growth in spring can be damaged by late frosts. Plants in this genus are notably resistant to honey fungus.
Propagating it: Seed - best sown as soon as it is ripe in a cold frame. Stored seed requires 3 months cold stratification at 5°c and should be sown as early as possible in the year. Very little of the seed produced in Britain is viable. Prick out the seedlings into individual pots when they are large enough to handle and grow them on in a greenhouse or cold frame for their first winter. Plant them out in early summer of the following year. Cuttings of half-ripe wood, July/August in a frame. Layering.
