Growth—

Prefers a good deep well-drained moisture retentive soil in full sun or semi-shade[1, 2, 3]. A dioecious species, both male and female forms must be grown if seed is required.

Propagation

Seed - best sown as soon as it is ripe. Stored seed may requires up to 3 months cold stratification, though scarification may also help[4]. Germination should take place within 6 months, though it might take another 12 months. Prick out the seedlings into individual pots when they are large enough to handle and grow them until large enough to plant out. Cuttings of half-ripe wood. Root cuttings, 3cm long, planted horizontally in pots. Good percentage[5]. Suckers, removed when the plant is dormant, and planted direct into their permanent positions[4].
