Description
Mahonia aquifolium, the Oregon grape, is a species of flowering plant in the family Berberidaceae, native to western North America. It is an evergreen shrub growing to 1 m (3 ft) tall by 1.5 m (5 ft) wide, with pinnate leaves consisting of spiny leaflets, and dense clusters of yellow flowers in early spring, followed by dark bluish-black berries.
The common name is often, and always in the United Kingdom, left unhyphenated as "Oregon grape", though doing so invites confusion with the true grapes.[citation needed] Some authors avoid this confusion by using "Oregon grape-holly" or "Oregon holly-grape" as a vernacular name for any species of Mahonia. It is also occasionally printed as "Oregongrape".
Mahonia aquifolium is not closely related to either the true holly (Ilex aquifolium) or the true grape
Several common species of Oregon-grape are known, and many have numerous cultivars. Among these are tall Oregon grape (Mahonia aquifolium); Cascade, low, dull, or dwarf Oregon grape (M. nervosa); and creeping Oregon grape
Mahonia aquifolium grows to 1–2 m (3 ft 3 in–6 ft 7 in) tall by 1.5 m (5 ft) wide, with pinnate leaves up to 30 cm (12 in) long, each leaf made up of spiny leaflets. The leathery leaves resemble those of holly and the stems and twigs have a thickened, corky appearance. The flowers, borne in dense clusters in late spring, are yellow, and are followed by spherical dark dusty blue berries, which give rise to the common name "Oregon grape"
