Creeping Oregon Grape (Mahonia repens) is a low-growing evergreen shrub with wonderful all-season interest. The holly-like leaves emerge with tints of red before turning glossy green for the summer, after which they will fade to a handsome burgundy for the winter months. Bright golden flowers appear on the plant from the end of spring to the beginning of summer, when they turn to clusters of blue or purple berries. These berries are edible, but very sour. Usually they are left on the shrub for willdlife. Creeping Oregon Grape makes an excellent groundcover in garden beds and borders, woodland and shade gardens, rock gardens, or erosion control for steep banks or slopes. It is somewhat tolerant of urban pollution.
