Oregon Grape

The Trader Mulberry is a rare find. Named for the Trader family who brought the mulberry from Germany when they immigrated to the U.S. in 1982 and planted the original tree at their new homestead in North Dakota. This tree still bears fruit today! Similar to the Illinois Everbearing, but more winter hardy, this mulberry is a cross between white and red mulberry trees. This vigourous tree will produce large, sweet-tasting, virtually-seedless, black fruit throughout the entire summer and is great for fresh eating, jams, and wine. Do not plant near walkways or driveways as the berries can stain.

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.
