Jewel Raspberry
Black Crowberry

The Jewel Raspberry is one of the most popular black raspberry varieties, as it is consistently high-yielding and produces large, firm, and sweet berries. This cultivar is among one of the first raspberries to ripen each year, with berries ready for harvest in early to mid summer and is a vigorous grower.

The Jewel Raspberry is self-pollinating, and is a primocane variety meaning that it produces fruit on first years' growth. Prune stalks down each winter or early spring to get higher fruit yields and easier harvesting.

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.
