The Oregon grape is a shrub of suckering habit, 1-1.5 in tall. It is a native of North America, where it grows in damp forests from California northward to British Columbia.
The pinnate leaves, measuring about 20 cm, are a glossy dark green, turning shades of copper and bronze in winter. The yellow flowers, borne in clustered racemes, appear in April. The bluish berries containing 3-5 seeds ripen in August and are edible. They are also used in preserves and to colour wines.
This is a valuable, evergreen ornamental shrub, widely cultivated in the parks of western, central and eastern Europe. It is sufficiently resistant to frost even in northern Germany, being damaged by spring frosts only if planted in sunny situations. It grows best in partial shade and does well even in drier situations. It is readily propagated by means of seeds or more usually by root suckers.
The black currant is a 1- 1.5 m high shrub of broadly branching habit. The twigs arc comparatively stout, greyish, and give off an unpleasant scent when cut. The buds are ovate, pale grey, on short stalks. The hermaphrodite red-green flowers appear in May. The black berries ripen in August.
In parks it is planted either as a solitary specimen or in taller hedges and shrubbery. It tolerates moderate shade and does not require much soil moisture. In locations subject to frost and in severe winters it tends to be partially damaged by frost.
Propagation from seed is quite laborious and therefore it is usually increased either by means of softwood cuttings in summer or hardwood cuttings in autumn. The pink or double-flowered forms are especially prized in parks.
