Propagation

Seed - probably best sown as soon as it is ripe in a greenhouse or cold frame[K]. Sow stored seed in spring in a cold frame[3]. Germination can be slow, often taking more than 12 months even when fresh seed is used[K]. When the seedlings are large enough to handle, prick them out into individual pots. Grow on the plants for at least their first winter in a greenhouse and plant out in late spring or early summer. Give the plants some protection from the cold for their first winter outdoors[K]. Cuttings of mature wood of the current year's growth, autumn in a frame.

Cultivation

Requires a moist, very well-drained neutral to slightly acid soil in full sun or light shade[3]. Succeeds in most soils[4]. Somewhat intolerant of frost, this species is only likely to succeed outdoors when grown in a woodland garden in the milder areas of Britain[3][4]. Hybridizes freely with other members of this genus[3][4]. Plants grown in Britain to date (1994) have not flowered[4]. Plants are tolerant of heavy clipping or pruning[4]. Plants are normally dioecious, though in some species the plants produce a few flowers of the opposite sex before the main flowering and a few hermaphrodite flowers are sometimes produced[4]. Male and female plants must usually be grown if seed is required.
