A deciduous shrub with hermaphrodite flowers pollinated by insects. Tolerates light sandy, medium loamy, and heavy clay soils with a preference for well-drained conditions. Grows in mildly acidic, neutral, or mildly alkaline soils. Suitable for semi-shade in light woodland or full sun, and prefers consistently moist soil.
How to Grow
Easily grown in a good well-drained loamy soil in sun or semi-shade. Sometimes cultivated for its edible fruit, there are some named forms. Plants in this genus are notably susceptible to honey fungus.
Propagation: Seed requires stratification and is best sown in early autumn in a cold frame. Stored seed requires one month stratification at about 3°c and should be sown as early in the year as possible. Prick out seedlings when large enough to handle and grow on in a cold frame, then plant out into permanent positions in late spring of the following year. Cuttings of half-ripe wood can be taken in July/August in a frame. Tip layering in July, planting out in autumn. Division can be done in early spring or just before leaf-fall in autumn.
Medicinal Uses
