Cultivation Details
Requires a moist, very well-drained neutral to slightly acid soil in full sun or light shade[1]. Succeeds in most soils[2]. Somewhat intolerant of frost, this species is only likely to succeed outdoors in the mildest areas of Britain[1]. Plants are hardy to at least -7°c in Australian gardens[3] though this does not translate directly to British gardens due to our cooler summers and longer, colder and wetter winters. Hybridizes freely with other members of this genus[1, 2]. Plants are tolerant of heavy clipping or pruning[2]. 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[2]. Male and female plants must usually be grown if seed is required.
Propagation
Seed - probably best sown as soon as it is ripe in a greenhouse or cold frame[PFAF]. Sow stored seed in spring in a cold frame[1]. Germination can be slow, often taking more than 12 months even when fresh seed is used[PFAF]. 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[PFAF]. Cuttings of mature wood of the current year's growth, autumn in a frame.
