Medicinal uses(Warning!)

Green osier was employed medicinally by a number of native North American Indian tribes who valued it particularly for its astringent bark which was used both internally and externally to treat diarrhoea, skin problems etc[4]. It is little used in modern herbalism.

The dried bark is used as an astringent, diaphoretic and stimulant[5][4]. The inner bark was boiled and the solution used as an enema[5] and this solution was also used as a tea to reduce fevers, treat influenza, diarrhoea, headaches, voice loss etc[5][4]. It was used as a wash for the eyes[4]. A compound infusion of the bark and roots has been used to treat childhood diseases such as measles and worms[4]. It has also been used as a wash on areas of the body affected by venereal disease[4].

A poultice of the powdered bark has been used to treat swellings, blisters etc[4].

Propagation

Seed - best sown as soon as it is ripe in a cold frame or in an outdoors seedbed if there is sufficient seed[6][7]. The seed must be separated from the fruit flesh since this contains germination inhibitors[6][8]. Stored seed should be cold stratified for 3 - 4 months and sown as early as possible in the year[8]. Scarification may also help as may a period of warm stratification before the cold stratification[6][8]. Germination, especially of stored seed, can be very slow, taking 18 months or more[8]. 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, July/August 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[9].

Layering of new growth in June/July. Takes 9 months[9].

Cultivation

An easily grown plant, it succeeds in any soil of good or moderate fertility[10], ranging from acid to shallow chalk[11]. Grows well in heavy clay soils and in dry soils. Succeeds in full sun or light shade[[12].

Plants are hardy to about -25°c[13]. A fast-growing but short-lived species in the wild[3], it is closely related to C. controversa[11]. This species is unusual in having alternate leaves whilst almost all other members of this genus have opposite leaves[14]. Plants have a thin bark and this makes them susceptible to forest fires[3]. There is at least one named form selected for its ornamental value[12].

Plants in this genus are notably resistant to honey fungus[11].
