Western Wild Cherry TreeThe Western Wild Cherry (P. demissa, Walp.) occurs west of the Rocky Mountains, and on to the Pacific. Closely related to the Eastern choke cherry, it differs in having thicker leaves and sweeter, scarcely astringent fruit.
It is easy to believe that these Western trees belong to the Eastern species, but are modified by climatic conditions into a new form. Where their ranges meet, it is hard to distinguish the two species.
