Cornus amomum is a deciduous shrub that produces a cluster of stems from 3 - 5 metres tall. The plant does not have a rhizomatous rootstock, but can spread somewhat by means of branches occasionally arching to the ground and rooting at the leaf nodes[
The plant is harvested from the wild for local use as a food and medicine, It is occasionally grown as an ornamental, where it can be used as a hedge and windbreak, but is considered to be best suited for woodland areas[
Eastern N. America - Iowa to Maine, south to Missisippi and Florida
Alluvial woods, river and stream banks, wet meadows, marshes, ditches; at elevations up to 1,500 metres[

Cornus amomum is a very cold-hardy plant, tolerating temperatures down to around -25°c when dormant.
Succeeds in full sun or light shade[
]. Prefers a moist, organically rich, slightly acidic soil in partial shade[
], though it is very tolerant and succeeds in any soil of good or moderate fertility[
], ranging from acid to shallow chalk[
]. Grows well in heavy clay soils.
Plants can start flowering when around 150cm tall[
The plant benefits from a 5 - 10cm deep mulch of organic matter, which will help to keep the roots cool and moist in hot weather[
Plants in this genus are notably resistant to honey fungus[
Fruit - raw or cooked[
]. Said to be very good to eat[
]. The fruit is 8mm in diameter[
Drupes blue, portion in direct sunlight bleached white, globose, 5–9 mm diam.; stone globose, 4–6 mm diam[
The dried root-bark is antiperiodic, astringent, stimulant (mild), tonic[
]. The flowers are said to have similar properties[
A tea or tincture of the astringent root bark has been used as a quinine substitute and also in the treatment of chronic diarrhoea[
]. It has also been employed in the treatment of painful urination, chest congestion etc[
The bark was also used as a poultice on external ulcers and as a wash for gonorrhoea sores[
The glycoside 'cornin' found in the bark has astringent properties[
The fruits are used as a bitter digestive tonic. A tincture of them has been used to restore tone to the stomach in cases of alcoholism[
The plant can be grown as a hedge[
]. It is often used as a windbreak in fields and near farmhouses in N. America[
It is sometimes planted on slopes to stabilize the soil[
The powdered bark is used as a toothpowder[
Seed - best sown as soon as it is ripe in a cold frame or in an outdoors seedbed if there is sufficient seed[
]. The seed must be separated from the fruit flesh since this contains germination inhibitors[
]. Stored seed should be cold stratified for 3 - 4 months and sown as early as possible in the year[
]. Scarification may also help as may a period of warm stratification before the cold stratification[
]. Germination, especially of stored seed, can be very slow, taking 18 months or more[
]. Prick out the seedlings of cold-frame sown seeds into individual pots as soon as they are large enough to handle and grow the plants on for their first winter in a greenhouse, planting out in the spring after the last expected frosts.
Cuttings of half-ripe side shoots, mid summer in a frame.
Cuttings of mature wood of the current year's growth, taken with a heel if possible, autumn in a cold frame. High percentage[
Layering of new growth in early summer/July. Takes 9 months[
