Green Alder
Diamond-Leaf Willow

Green Alder is a cold hardy, native shrub. It is often planted on infertile sites so it can fix nitrogen from the air and improve the soil quality.

Green Alder is known for its smooth grey bark and attractive shiny green leaves; it is commonly used in reclamation.

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.
