Oregon Grape Grape Seeds - Mahonia aquifolium

Oregon Grape (Mahonia aquifolium) is a hardy, evergreen shrub native to the Pacific Northwest. It’s renowned for its glossy, holly-like foliage, clusters of bright yellow flowers in early spring, and tart, blue-purple berries that ripen in late summer. Both ornamental and useful, the berries are edible and rich in vitamin C, often used in jellies and natural dye production.

This Non-GMO Oregon Grape Shrub thrives in various soil conditions and is drought-tolerant once established. It’s also highly valued for erosion control, pollinator support, and year-round color in shade gardens or naturalized plantings.
