Oregon Grape
Chester Thornless Blackberry

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.

Chester Thornless Blackberry is a self-pollinating fruit-bearing shrub. In mid-summer, the Chester Thornless Blackberry produces large, sweet-tasting, heart-shaped blackberries that are perfect for fresh eating. It is a semi-erect blackberry plant that requires little support from a trellis to keep its fruit off the ground. Don't forget to protect your berries. The birds love this shrub almost as much as you will.

Chester Thornless Blackberries are floricanes, primarily fruiting on second year canes. Each spring cut back all two-year old canes, leaving only the last year’s growth.
