Prunus virginiana var. demissa (Rosaceae) is the western variety of chokecherry, native from British Columbia south to California and east to the Rocky Mountain states. It is similar to the species but typically smaller (15 to 25 feet) and adapted to drier conditions.

Western chokecherry grows in sun to part shade on well-drained soils from sea level to moderate elevations. It shares the suckering habit, wildlife value, and fruit characteristics of the species. Like the eastern form, it is susceptible to black knot disease. Hardy in Zones 3a to 8b.
