Alnus incana subsp. rugosa

Common name: Speckled Alder

Native plant

This native alder tends to be multi-stemmed and is best used in groups in wet areas and flood plains. Branches with small cones and catkins make excellent winter arrangements. This plant fixes nitrogen in the soil that can be used by other plants. This is one tree I definitely recommend buying in #5 containers because of its rapid rate of growth (3-4 feet per year). Alder has limited use as a street tree.
