The fruit is often persistent well into the winter and is eaten by birds and mammals. Leaves vary somewhat in shape, texture, and pubescence, but recognition of named variants does not seem warranted. Most often the blades are ± obovate and resemble those of choke cherry (Prunus virginiana) in shape. The yellow-fruited form, f. chrysocarpa B. L. Rob., has been occasionally observed in Michigan.
