Fruits: Berries are 4-7 mm diameter, ovoid; dark blue with a yellow bloom; contain a few large seeds 4-5 mm long; flowers are born in an elongated cluster.

Uses: Low Oregon Grape has been used as an ornamental species for decades.  It is favored for its bright yellow flower clusters in spring, the dark purple berries in late summer, and the reddish green leaf color in fall and winter.  The berries have been used (when absolutely ripe) for preserves.

Conservation Uses: Oregon Grape has numerous uses as a conservation species in the state. Its berries are a favored food of many species of birds and rodents, and the young stems and leaves can serve as forage (reluctantly) for deer and elk. It develops an extensive root system in time, making it a good soil stabilizer.

Helpful Tips: Oregon Grape can be slow to establish, and may require supplemental irrigation and weed control during the first growing season.  As with any new planting, it should be watered during the dry season for the first 2-3 years.
