River Alder vs Silverberry (Wolf Willow)

Alnus incana

Elaeagnus commutata

River Alder
Silverberry (Wolf Willow)

River Alder is a large shrub or small tree with a multi-stemmed, spreading habit. A shrub native to the boreal forests across North America, River Alder is an excellent tree for soil stabilization near rivers and creeks.

This tree is recognizable by its small brown seed cones and smooth, silver-grey bark with white horizontal lenticels. Unlike Green Alder, River Alder's seed pods are long and hang off short branches.

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

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 grown on dry to moist sandy/gravel soils.

This plant is very low maintenance.
