The Hazel Alder (Alnus serrulata) is a small, deciduous tree or shrub native to the eastern United States, often found in wetland areas, along streambanks, and in damp forests. It typically grows 10–20 feet tall with a rounded or spreading form. The plant is characterized by its smooth, gray bark, oval to elliptical leaves with finely serrated edges, and clusters of reddish catkins that appear in early spring before the leaves emerge. Small, cone-like seed structures develop in late summer, providing food for wildlife. The Hazel Alder is valued for its ability to stabilize soil, improve nitrogen levels, and support wetland ecosystems.
