Physical Characteristics

An evergreen shrub growing to 15m by 1.5m at a slow rate. It is hardy to zone 5. It is in leaf all year, in flower from May to June, and the seeds ripen from November to December. The flowers are dioecious (individual flowers are either male or female, but only one sex is to be found on any one plant so both male and female plants must be grown if seed is required) and are pollinated by Bees. The plant not is self-fertile. We rate it 2/5 for edibility and 2/5 for medicinal use.

The plant prefers light (sandy), medium (loamy) and heavy (clay) soils. The plant prefers acid, neutral and basic (alkaline) soils. It can grow in semi-shade (light woodland) or no shade. It requires moist soil. The plant can tolerates strong winds but not maritime exposure.

Habitats and Possible Locations

Hedge, Woodland, Secondary, Dappled Shade, Shady Edge.

Edible Uses

Tea.

The roasted leaves are used as a tea substitute[161, 177]. They do not contain caffeine[183]. The drink was a very popular tea substitute during the American Civil war[183].

Medicinal Uses

Disclaimer

Antiperiodic; Diuretic; Emetic; Laxative; Ophthalmic; Skin.

The berries are laxative, emetic and diuretic[222]. They are used in the treatment of children's diarrhoea, colic and indigestion[222].
A tea made from the leaves has been used as a treatment for measles, colds etc[222, 257]. The leaves have also been used externally in the treatment of sore eyes, sore and itchy skin[222, 257].
A tea made from the bark was once used in the treatment of malaria and epilepsy[222]. It has also been used as a wash for sore eyes and itchy skin[257].

Other Uses

Dye; Hedge; Shelterbelt; Wood.

A number of cultivars of this species are used for hedging[200]. Fairly wind-resistant, this species is also used in shelterbelt plantings[200].
A dye has been made from the berries - the colour is not given[257].
Wood - light, tough, not strong, close grained, highly shock resistant, easily worked[82, 149, 171, 229]. A strikingly white wood, it is valued for use in veneers and inlay[274]. It weighs 36lb per cubic foot[235]. Too small for commercial exploitation, but it is valued for use in cabinet making and the interior finishes of houses[82], it is also used for making small items such as tool handles[149, 171, 229]. The wood can also be stained to imitate ebony[171].

Cultivation details

Succeeds in most soils so long as they are not water-logged. Fairly wind-resistant[200].
Plants are hardy to about -25°c[184].
A slow-growing and long-lived species in the wild[229], but it does not thrive or fruit well in British gardens[182]. Plants do not thrive in a maritime climate[188]. There are many named forms, selected for their ornamental value[182, 200].
The leaves remain on the plant for about 3 years, falling in the spring[82].
Flowers are produced on the current year's growth[229].
Resents root disturbance, especially as the plants get older[11]. It is best to place the plants into their permanent positions as soon as possible, perhaps giving some winter protection for their first year or two[K].
Plants are very tolerant of pruning and can be cut right back into old wood if required[188].
Dioecious. Male and female plants must be grown if seed is required.

Propagation

Seed - best sown as soon as it is ripe in the autumn in a cold frame. It can take 18 months to germinate. Stored seed generally requires two winters and a summer before it will germinate and should be sown as soon as possible in a cold frame. Scarification, followed by a warm stratification and then a cold stratification may speed up the germination time[78, 80]. The seedlings are rather slow-growing. Pot them up into individual pots when they are large enough to handle and grow them on in light shade in a cold frame for their first year. It is possible to plant them out into a nursery bed in late spring of the following year, but they should not be left here for more than two years since they do not like being transplanted. Alternatively, grow them on in their pots for a second season and then plant them out into their permanent positions in late spring or early summer. Give them a good mulch and some protection for their first winter outdoors.
Cuttings of almost ripe wood with a heel, August in a shaded position in a cold frame. Leave for 12 months before potting up.
Layering in October. Takes 2 years.

Cultivars

'': There are some named forms for this species, but these have been developed for their ornamental value and not for their other uses. Unless you particularly require the special characteristics of any of these cultivars, we would generally recommend that you grow the natural species for its useful properties. We have, therefore, not listed the cultivars in this database[K].
