Mahonia aquifolium
Oregon Grape
Description
This Oregon native is an evergreen broadleaf shrub that reaches 4-5' tall and wide. This shrub is upright although it can get leggy. Dark green, glossy, stiff and leathery leaves have spines along margins. Foliage may turn bronze-burgundy during winter. Bright yellow flowers appear in spring, followed by blue-black berries in summer. Birds love the berries. This shrub does well in full or part sun with moist, acidic, well-draining soil. It does not tolerate hot areas such as parking strips or parking lots as well as drying winds. Prune about one third of older stems back to 6" long stems so plant will be refreshed with new growth. This is the state flower of Oregon. Many cultivars now available.
