Sweet Gale
Diamond-Leaf Willow

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.

Diamond-Leaf Willow is a native deciduous shrub known for its glossy diamond-shaped leaves, which give the shrub its name. Its catkins emerge in spring, providing an important early source of pollen for pollinators. The shrub’s dense growth also offers valuable cover and browse for wildlife, including moose and deer.

This shrub is well-suited to cool, moist habitats such as wetlands, streambanks, and forest openings. It spreads by rhizomes, helping to stabilize soils and form dense thickets. Diamond-Leaf Willow is valuable for reclamation, wetland enhancement, shelterbelt plantings, and a wide range of conservation and habitat restoration projects.
