The Tall Oregon Grape Plant has good autumn leaf color, abundant clusters of yellow flowers, and dark black, edible fruits have made this handsome, spiny leaved evergreen shrub a widely promoted ornamental, especially in the American West.

Less well known are its medicinal properties, which have long been used by the first peoples and others.

The glossy leaves are pinnately divided into five to thirteen leaflets, each of which resembles a holly leaf. Red when newly open, the leaves become dark green in summer, then purplish or bronze in fall and winter, particularly when planted in sun and where winters are cold.

The dense clusters of tiny flowers, which appear in March through May, are 5 to 8 cm long and slightly fragrant. Grape like berries 1cm in diameter ripen in July through September and are the source of the plant’s common name,  Holly Grape.
