Fast-growing, thicket-forming large shrub with multiple trunks. Commonly called speckled alder due to the white lenticels (pores) that speckle the bark. Male and female flowers appear in separate catkins in early spring before the leaves emerge. Female catkins are followed by fruiting cones containing winged seeds attractive to birds. Cones resemble small pine cones and persist through the winter. Roots bear nitrogen-fixing nodules. Tolerates mucky soils, clay soils, and occasional flooding. Thickets provide cover and winter browse for wildlife. Attracts butterflies and seed-eating birds. Larval host to Green Comma butterflies.
