Cultivation Details

Requires a moist, very well-drained neutral to slightly acid soil in full sun or light shade[]. Succeeds in most soils, so long as they are well-drained[]. This plant has survived very dry conditions with us and appears to be very drought tolerant[].
One of the hardiest members of this genus, it succeeds outdoors in the rock garden in many parts of the country[].
Hybridizes freely with other members of this genus[, ], though it does not seem to cross with C. pumila, C. atropurpurea or any red-fruited species[]. There are several named forms selected for their ornamental value[].
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[]. Male and female plants must usually be grown if seed is required.

Edible Uses

Fruit - raw or cooked. Sweet, but without much flavour[]. The fruits vary in colour from white to blue or sea-green[]. The fruit is seldom borne in Britain[]. The fruit is about 12mm wide[].
The roasted seed is an excellent coffee substitute[].

Medicinal

Other Uses

A yellow dye is obtained from the wood, it does not require a mordant[].
A dense carpeting plant, it can be planted about 25cm apart to form a ground cover[]. The cultivar 'Violet Drops' is much more vigorous than the type, forming compact mats up to 2 metres across and making a very good ground cover[].

Propagation

Seed - probably best sown as soon as it is ripe in a greenhouse or cold frame[]. Sow stored seed in spring in a cold frame[]. Germination can be slow, often taking more than 12 months even when fresh seed is used[]. 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[].
Cuttings of mature wood of the current year's growth, autumn in a frame.
