Silverberry (Wolf Willow)
Black Crowberry

Silverberry (also known as Wolf Willow) is a common native North American shrub. This beautiful ornamental plant has characteristic silver leaves and fragrant yellow flowers.

Its silver berries remain on the branches through the winter. Silverberry is cold hardy and has some ability as a nitrogen fixer. It can grow on dry to moist sandy/gravel soils. This plant is very low maintenance.

Black Crowberry is a native evergreen shrub that forms low, spreading mats. It has unique foliage that spiral around the stem, and small dark berries, giving it visual appeal. The berries are edible, but can be acidic, so are not generally eaten fresh. In colder climates they have a sweet, tart taste, and are dried, used in deserts, or for making jams or jellies.
It provides food for birds and mammals, while its flowers attract pollinators such as bees. Its ability to grow in harsh climates makes it an important species for ecological balance.
Black Crowberry has historical significance as it provided a vital food source for the indigenous cultures of the arctic regions. It is abundant in Scandinavia and is used to make liqueurs, wines, and juices. In Newfoundland and Labrador the berries are known locally as ‘blackberries’ and are used in jams, jellies and baked goods like buns and puddings.
