|Berberis vulgaris is a medium large evergreen shrub, 6 to 10 feet tall, produces many erect stems from the base, that arch outwards from the top resulting in a graceful pendulous form. Leaves are 1 to 2 inches long, dull green, yellow flowers borne on 2 to 3 inch racemes appear in late spring. Barberry fruit is a red or purple, 1/2 inch, egg-shaped berry, ripens in the fall, persist into winter, quite effective fall color. This shrub has escaped and naturalized in the U.S. and is unfortunately the alternate host of wheat rust, Puccinia graminis. In some states it is considered a noxious weed. Native to Europe, north Africa and cool areas of Asia.
