Bog Birch is a hardy, deciduous shrub native to North America. It thrives in wetlands, riparian zones, and boreal forests, and can be found as far north as the Arctic Circle—making it one of the few woody plants to grow in such extreme climates.

In Western Canada, it is especially common in moist lowlands, along streambanks, and in peatlands. Beyond its ecological role in stabilizing soils and supporting wildlife, Bog Birch is frequently used in reclamation and restoration projects due to its resilience and ability to establish quickly in disturbed or degraded landscapes.

Note: We use Bog Birch for Betula pumila. This species is also known by many other common names, including Dwarf Birch, Swamp Birch, and others. Please confirm the scientific name to ensure you are ordering the correct plant.

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.
