				Japanese Barberry - Berberis thunbergii Family: Berberidaceae THIS PAGE IS UNDER CONSTRUCTION Status: Invasive Location info: Berberis thunbergii (Japanese barberry or Thunberg's Barberry) is a species of Berberis, native to Japan and eastern Asia. Info: It is widely grown as an ornamental plant, both in Japan and elsewhere in the temperate Northern Hemisphere. Numerous cultivars have been selected, including plants selected for yellow, dark red to violet, or variegated foliage, erect growth (for hedge use), and dwarf size. In recent years it has become an invasive species in parts of the eastern United States; in Canada its cultivation is prohibited as the species can act as a host for Puccinia graminis (black rust), a rust disease of wheat. Currently there are breeding and selection programs aimed at producing cultivars that are either sterile or produce relatively little seed. It is sometimes confused with Berberis canadensis (American Barberry), Berberis vulgaris (European Barberry), and other deciduous Berberis species; it is most readily distinguished by the flowers being produced in umbels, not racemes.
