Almost everywhere except wet ground. Even more than P. serotina, a species of fencerows and roadsides, dry open rocky and sandy ground, shores and openings, as well as dune thickets, jack pine plains, and river banks; often at borders of forests and in open forests, but not an important forest species.
The leaves are usually glabrous beneath. If there is pubescence along the midrib or in tufts in axils of the lateral veins, it extends out along the lateral veins instead of being restricted to the midrib as in P. serotina. The veinlets form a characteristic fine network of very small areas. Choke cherry is a shrub or at best a small tree. The fruit, deep red-purple when ripe, nearly or quite as dark as in P. serotina, is extremely astringent, puckering the mouth of anyone who experiments with it.
The European Prunus padus is sometimes cultivated, and known as an escape in some adjacent parts of the United States, though not yet in Michigan. It is like P. virginiana, but with larger petals (definitely longer than the stamens).
