Black Crowberry

Black Crowberry is a native evergreen shrub that forms low, spreading mats. It has unique foliage that spirals around the stem, and small dark berries, giving it visual appeal. The berries are edible, but can be acidic, so they are not generally eaten fresh. In colder climates, the berries develop a sweet-tart flavor and are often dried or used in desserts, jams, and jellies.

This hardy shrub provides food for birds and mammals, while its flowers attract pollinators such as bees. It also serves as a host plant for certain butterflies and moths. Together, these roles make it a key contributor to the health of tundra and boreal ecosystems.

In Newfoundland and Labrador, the berries are known locally as ‘blackberries’ and are enjoyed in jams, jellies, and traditional baked goods such as buns and puddings. In Scandinavia, they continue to be used in liqueurs, wines, and juices.

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.
