Mahonia is a genus of about 70 species of evergreen shrubs in the family Berberidaceae, native to eastern Asia, the Himalayas, North America and Central America. They are closely related to the genus Berberis. Botanists disagree on the acceptability of the genus name Mahonia. Several authorities argue plants in this genus should be included in the genus Berberis because several species in both genera are able to hybridize, and because when the two genera are looked at as a whole, there is no definite morphological separation. For more information on this consult the Flora of North America. Mahonia typically have large, pinnate leaves 10-50 cm long with 5-15 leaflets, and flowers in racemes(5-20 cm long).
The genus name Mahonia honors the Philadelphia horticulturist Bernard McMahon who introduced the plant from materials collected by the Lewis and Clark Expedition.
Several species are popular garden shrubs, grown for their ornamental evergreen foliage, yellow flowers in winter/early spring, and blue-black berries. The berries are edible, and rich in vitamin C, though with a very sharp flavor.
