Berberis (/ˈbɜːrbərɪs/) is a large genus of deciduous and evergreen shrubs from 1–5 m (3.3–16.4 ft) tall found throughout the temperate and subtropical regions of the world (apart from Australia). Species diversity is greatest in South America, Africa and Asia; Europe and North America have native species as well. The most well-known Berberis species is the so-called European barberry, Berberis vulgaris, which is common in Europe, North Africa, the Middle East, and central Asia. Many of the species have spines on the shoots and along the margins of the leaves.
