Diamond-Leaf Willow

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.

Used to growing in the shadows of the damp forest, White Maple (aka Mountain Maple) is a great fit for shady and wet areas, such as beneath larger trees. Unlike most of its cousins, the White Maple is a shrub instead of a tree. It's still a maple, however, with sap that can be made into Maple syrup to prove it!

In May and June, the classic shapes of Maple leaves are joined by clusters of green and yellow flowers. Soon after, red samaras (aka helicopter seeds or whirligigs) appear. This distinctive appearance makes White Maple an excellent choice for giving urban yards a unique (and patriotic) look.
