The Oregon grape (Mahonia aquifolium) is a perennial evergreen shrub native to the Pacific Northwest. It features holly-like, spiny leaves, clusters of bright yellow flowers in spring, and dark blue-black berries. The berries, while edible, are tart and often used in jellies or wines when sweetened. Indigenous peoples of the Pacific Northwest have utilized the plant for both food and medicine; the roots and inner bark were traditionally used to make yellow dye and as a remedy for digestive and skin ailments due to their antibacterial properties. Ecologically, Oregon grape serves as a valuable food source for birds and pollinators and thrives in various habitats, from forests to dry, rocky slopes. Its drought tolerance makes it an excellent plant for erosion control and habitat restoration.
