Mixed and coniferous forests and thickets, including deciduous forests and forested bluffs or banks, conifer swamps; sometimes growing with A. pensylvanicum but usually in somewhat moister forests.
This is a large shrub or small bushy tree, at the very most the stems about 25 cm in diameter. The leaves may be orange or red in the fall. It is more pubescent than A. pensylvanicum in all its parts: inflorescence, young fruits, lower surface of leaves, twigs. Both retain their fruit into late summer or fall, whereas the early-flowering species (A. rubrum and A. saccharinum) have generally lost their fruit by early summer.
