Blackcurrant

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.

Blackcurrant is a medium-sized shrub producing delicious, deep purple to black sweet berries suitable for jams, jellies, syrups and cordial.

Our Blackcurrant is grown from seed from the "Ben" series of Blackcurrant cultivars, developed by the Mylnefield Research Station in Scotland with a focus on cold hardiness and heavy commercial fruit production. Our seedlings will be slightly different due to hereditary differences but will be very similar to this series.
