Ninebark
Dwarf-Bog Birch

Ninebark is a small, multi-stemmed shrub, that is used to add texture or colour to any yard.

It features flaky, cinnamon-brown bark, attractive white flowers, and long, maple-like leaves.

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.
