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, and included within that genus by some botanists; they are distinguished from Berberis by their large, pinnate leaves 10-50 cm long with 5-15 leaflets, and flowers in longer (5-20 cm long) racemes.
