About Oregon grape
Mahonia aquifolium, also known as Oregon grape, is an evergreen shrub native to western North America. It stands out for its shiny, spiny, dark green leaves that turn reddish in winter, as well as its showy yellow flower clusters and dark blue berries. It is ideal for hedges, borders, or as an ornamental plant in low-maintenance gardens and partial shade.
Native range
North America (from southeastern Alaska to northern California)
Care tips
It prefers partial to full shade locations, though it tolerates some sun if the soil is kept moist. Watering should be moderate, allowing the top layer of the substrate to dry between waterings, and more frequent in summer. It requires well-drained soil, rich in organic matter, and slightly acidic. A common mistake is planting it in full sun without sufficient moisture, which can lead to leaf scorch.
