Botanic information
Leaf: The dark green imparipinnate leaves are up to 300 mm (1 ft) long and have 5-7 elliptical to ovate leaflets that are up to 130mm (5in) long with an acute apex. The underside is pale green and the leaves turn yellow during autumn. When crushed they are aromatically vile.

Flower: The small creamy white stellate flowers are up to 6 mm (¼ in) wide and are arranged in a large flattish compound cyme that is up to 180mm (7in) wide. It is held above the foliage on a slender scape and appears during the early summer.

Fruit: A large crop of green to black, berry-like fruit is produced and the small seeds are viable but the plant is commonly reproduced vegetatively. 

Note:
The fruit is used to preserve or colour jams and pies and is also commonly used to make wine. Care should be taken as the raw fruit may contain toxins that cause stomach upset. All toxins are removed during cooking.
