Summary

Mahonia aquifolium, commonly known as Oregon grape or holly-leaved barberry, is an evergreen shrub native to the understory of coniferous forests in western North America, including regions from British Columbia to southern California, often found in the shade of larger trees. It typically grows 1 m (3 ft) to 3 m (10 ft) tall and 1.5 m (5 ft) wide. The plant features pinnate leaves with spiny leaflets resembling holly and produces dense clusters of yellow flowers in early spring, which are quite showy and give way to spherical, dark bluish-black berries. The berries are not only ornamental but also edible, though tart.

Oregon grape is appreciated for its year-round ornamental appeal, with striking evergreen foliage that provides texture to shaded garden areas. It is a low-maintenance plant that can adapt to a range of soil conditions, though it prefers a well-drained, acidic soil. It is often used in shady or woodland garden settings, as an understory plant, or in naturalized areas. The plant’s ability to thrive in part shade to full shade and its drought resistance once established make it a versatile choice for gardeners. Additionally, its berries are a food source for birds, enhancing its wildlife value. However, gardeners should be aware that it can be potentially invasive outside its native range and may require control measures to prevent spreading.CC BY-SA 4.0
