Oregon Grape Brings Color to the Garden All Year While Supporting Bees and Birds
Grow this evergreen shrub, native to Pacific Northwest woodlands, for its bright flowers and fruits
Oregon grape (Berberis aquifolium, syn. Mahonia aquifolium) brings color to the garden across several seasons while also providing for pollinators and birds. This Pacific Northwest native shrub needs little maintenance and fits a few roles in the garden and landscape. With its tall and narrow shape, it can serve as a single accent plant or it can be planted in multiples to create a hedge or screen.
Common name: Oregon grape, holly-leaved barberry
Botanical name: Berberis aquifolium, syn. Mahonia aquifolium
Origin: Berberis aquifolium is native to the Pacific Northwest region of the United States, including Northern California. Its range extends into British Columbia, Canada. Its habitat includes deep conifer forests and open woods.

Growing Oregon grape
Exposure: Sun or shade
How to grow it: Plant Oregon grape in well-drained soil and any level of light. Full sun will encourage a more compact habit and better flowering and fruiting, but the shrub may need supplemental watering. In part sun to shade, it can tolerate drought once established, but its shape may be more leggy as it reaches for light. In any position, keep it evenly watered during its first season in the garden and ahead of winter each year. Avoid a spot subject to harsh winter winds, which can dry the plant out. USDA Zones 5–9.
