Silverberry (Wolf Willow)
Dwarf-Bog Birch

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.

Dwarf-Bog Birch is a native, cold-hardy shrub that can be found across most of Canada. Its preference for moist soils and the extensive root system make it well-suited for riparian zone plantings, soil stabilization, and erosion control projects.
It features small, round, leathery leaves with scalloped edges and produces small, cone-like catkins. A distinguishing characteristic of the Dwarf-Bog Birch is the presence of large resin glands on the branches and the undersides of the leaves. These resin glands are the reason for its scientific name, Betula glandulosa.
Note: We use Dwarf-Bog Birch for Betula glandulosa. This species is also known by many other common names, including Bog Birch, Dwarf Birch, Glandular Birch, and others. Please confirm the scientific name to ensure you are ordering the correct plant.
