Dwarf Birch, also known as Bog Birch for its common occurrence in wet areas, is a small deciduous shrub native to North America.

Found growing up into the arctic circle, this is one of the few trees that grows that far north.

Common in riparian zones and boreal forests across Western Canada. It is a common reclamation species.

This species is often used by local artisans to twist into shapes like willow and make decorative hearts, circles, etc.

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.
