الوصف
It is a deciduous shrub or small tree growing to 4–5 m (13–16 ft) tall. The leaves are opposite, simple oval to lanceolate, 6–13 cm (2.4–5.1 in) Long and 4–9 cm (1.6–3.5 in) broad, with a finely serrated margin; they are densely downy on the underside, less so on the upper surface. The hermaphrodite flowers are small, around 5 mm (0.20 in), and creamy-white, produced in dense cymes 4–10 cm (1.6–3.9 in) width at the top of the stems; they are produced in early summer, and pollinated by insects. The fruit is an oblong drupe 8 mm (0.31 in) long, green at first, turning red, then finally black at full maturity, and contains a single seed. The seeds are dispersed when birds eat the fruit, then deposit the seeds in another location in their droppings.[2][3]
An older name for the plant is hoarwithy. "Hoar" means grey-haired and refers to the hairs under the leaves, and "withy" means a pliant stem.[4]
الاستزراع والاستخدامات
It is commonly grown as an ornamental plant for its flowers and berries, growing best on alkaline soils. A number of cultivars have been selected, including 'Aureum', with yellow leaves in spring.[3]
The fruit is of low to zero toxicity, but may cause vomiting or diarrhea if consumed unripe or in large quantities.[5]
