Oregon Grape
Riverbank Grape

Oregon Grape is an evergreen shrub native to North America, found along the Pacific coast. In spring, the bright golden-yellow flowers appear in clusters above the leaves. These flowers eventually give way to edible blue berries in late summer. While not a true grape, the berries appear grape-like due to their colouring and clustered growth. They can be eaten fresh, but the sour taste and high amounts of natural pectin make them well suited for preserves.

The Oregon Grape has leaves that are glossy, leathery, and spiny-edged. This feature gives it its alternate name of Holly-leaved Barberry. When the leaves emerge in the spring they are a bronze-red colour. In the summer they transition to green, followed by bright red to deep burgundy in the fall. Leaves are retained throughout the winter and colder temperatures cause the leaves to turn purplish bronze, providing year round interest to the landscape.

The Riverbank Grape, also known as the Frost Grape, or Wild Grape, is a cold-hardy variety that produces fragrant white flowers in the spring and then tart, purple grapes late in the summer.

The Riverbank Grape is a vigorous grower that attracts lots of wildlife, who enjoy the fruit and flowers. This plant is native to North America, and is also highly resistant to fungal diseases, making this a great addition to your city gardens. This plant does best with a trellis.

Note: We do not ship grape vines to BC due to regulatory restrictions from the Canadian Food Inspection Agency.
