Edible Uses
Edible Parts: Fruit | Edible Uses: CoffeeFruit - raw or cooked[173]. The fruit is freely borne, it is sweet but has little flavour[225]. The orange fruit is about 9mm long x 5mm wide[200, 225]. The roasted seed is a coffee substitute[153, 173]. It is said to make an excellent coffee, though the seeds are rather small[225].
Cultivation
Requires a moist, very well-drained neutral to slightly acid soil in full sun or light shade[200]. Succeeds in most soils[225]. Somewhat intolerant of frost, this species is only likely to succeed outdoors in the mildest areas of Britain[1, 200]. Plants are fairly hardy in Essex according to another report, which says that they are worthy shrubs for a woodland garden[225]. There are some named forms, selected for their ornamental value[225]. Hybridizes freely with other members of this genus[200, 225]. Plants are tolerant of heavy clipping or pruning[225]. Plants are normally dioecious, though occasionally the plants produce a few flowers of the opposite sex before the main flowering and a few hermaphrodite flowers are sometimes produced[44, 225]. Male and female plants must usually be grown if seed is required.
