Oregon Grape

Oregon Grape (Mahonia aquifolium)

Oregon Grape (Mahonia aquifolium) is a rugged, evergreen shrub native to the Pacific Northwest, valued for its spiny, holly-like leaves, vibrant yellow spring flowers, and deep blue berries. This low-maintenance plant offers year-round visual interest and ecological benefits, making it a versatile option for native gardens, shady borders, and erosion control on slopes. Its adaptability and bold texture make it a useful focal point in naturalized or structured landscapes alike.

Distinctive Features

Mahonia aquifolium features glossy, leathery foliage that emerges bronze-red in spring, turns deep green in summer, and takes on purplish tones in winter. In early spring, clusters of fragrant, bright yellow flowers emerge, attracting pollinators before most other plants bloom. These are followed by powdery blue, grape-like berries that persist into summer and are enjoyed by birds. Plants typically reach 3 to 6 feet tall and wide, forming colonies over time through suckering.
