Subspecies
The two subspecies of Prunus serotina:
- P. s. subsp. serotina - Canada, United States
- P. s. subsp. capuli (Cav.) McVaugh — Mexico, Guatemala
The typical subsp. P. s. serotina is sometimes further divided into four varieties, var. serotina in the east of the range, var. eximia in Texas, and vars. rufula and virens in Arizona, New Mexico and Texas.
Black cherry is closely related to the chokecherry (Prunus virginiana); chokecherry, however, is classified as a shrub or small tree and has smaller, less glossy leaves.
