Japanese Barberry

Japanese Barberry ( Berberis thunbergii DC) was introduced in 1875 and promoted as an ornamental substitute for common barberry (Berberis vulgaris), which is a host for black stem rust. Prevalent in the East and Midwest of the United States, it forms dense stands that compete with native trees and plants (from USDA Plant Profiles).
