Sweet Gale is a native, nitrogen-fixing shrub known for its aromatic foliage. Tiny glands on the leaves release a balmy, bay leaf-like scent with floral and citrus notes. In spring, the yellowish male catkins provide one of the earliest sources of pollen for bees and other insects. While later in the season, the female catkins produce seeds that are eaten by waterfowl. Sweet Gale is dioecious, meaning male and female flowers occur on separate plants.

Sweet Gale thrives in wet, acidic soils and is commonly found along wetlands and lakeshores. It can help stabilize shorelines, while its dense growth provides valuable cover for wildlife. It is well-suited for naturalization, wetland restoration, and erosion control projects.

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.
