Silverberry (Wolf Willow)
River Alder

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.

River Alder is a large shrub or small tree with a multi-stemmed, spreading habit. It is an excellent tree to plant if you want to stabilize the soil near rivers and creeks.

Unlike the other alder varieties, River Alder is attractive enough to be included in riverside plantings by municipal and provincial park organizations.
