Silverberry (Wolf Willow)
Souris Raspberry (an improved Boyne Raspberry)

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.

Souris is an improved version of Boyne, the classic prairie raspberry. It is planted all across Canada and is extremely robust. Where other raspberry cultivars rely on unique selling points and specializations, Souris is just generally a great raspberry.

Souris is cold hardy and resistant to disease and spider mites. Its berries are deliciously sweet and tart while colourful, great for U-pick operations, fresh eating, or using in products such as jams and pies. They can be a bit softer than other raspberry varieties.

The Souris Raspberry is a fast-growing floricane. This means that raspberries will not grow on canes the year they first grow. The mature canes they do grow on, however, produce more berries than primocane varieties.
