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[2]. 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

This section contains historical Plants For A Future notes marked noncommercial.

Requires a moist, very well-drained neutral to slightly acid soil in full sun or light shade[2]. Succeeds in most soils, so long as they are well-drained[3]. Somewhat intolerant of frost, this species is only likely to succeed outdoors in the milder areas of Britain[2]. Plants are proving to be hardy in an Essex garden[3]. Hybridizes freely with other members of this genus[2][3]. 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[3]. Male and female plants must usually be grown if seed is required.
