Arnold Hawthorn

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.

Arnold Hawthorn is a low-branched tree favored by wildlife and landscapers. This tree's beautiful white flowers and bright red berries make it an attractive ornamental in anyone's yard. Arnold Hawthorn is also used in windbreaks and riparian planting.

Despite its thorns, Arnold Hawthorn is a popular choice of food and shelter for deer and birds. Humans can also eat these berries fresh or preserved, but Arnold Hawthorn will not have high yields until it matures at 5-8 years.
