Common Caragana
Black Crowberry

Common Caragana is a fast growing shrub that's known for its exceptional hardiness and drought tolerance. Although it's most commonly planted in shelterbelts, Common Caragana is also an excellent hedge or feature shrub.

Note: in warmer areas, this species can be difficult to contain once planted. Use the right plant in the right place.

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.
