Dwarf-Bog Birch

Common Caragana is a fast growing shrub that's known for its exceptional hardiness and drought tolerance. Although it's most commonly planted in shelterbelts, Common Caragana is also an excellent hedge or feature shrub.

Note: in warmer areas, this species can be difficult to contain once planted. Use the right plant in the right place.

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.
