Grey Alder
Diamond-Leaf Willow

River Alder is a large shrub or small tree with a multi-stemmed, spreading habit. It is an excellent tree to plant if you want to stabilize the soil near rivers and creeks.

Unlike the other alder varieties, River Alder is attractive enough to be included in riverside plantings by municipal and provincial park organizations.

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.
