Chokecherry is widely distributed throughout southern Canada and much of the United States. It occurs from Newfoundland to British Columbia and south to North Carolina, Tennessee, Missouri, Kansas, Oklahoma, Texas, New Mexico, California, and northern Mexico. Plants showing a gradation from black chokecherry to common chokecherry occur in Kansas and Nebraska.
This plant is present in at least 55 states/provinces in this country.
Chokecherry is a native, deciduous, thicket-forming erect shrub or small tree. Stems are numerous and slender, either branching from the base or with main branches upright and spreading. Heights vary considerably according to variety and site quality, ranging from 3 to 19.5 feet (1-6 m). In the Great Basin, chokecherry may grow to almost 40 feet (12 m) with trunk diameters of approximately 8 inches (20 cm). Perfect flowers are borne on leafy twigs of the season. Fruits are drupes, each containing a small stone. Chokecherries have a network of rhizomes and a deep root system established at intervals along the rhizomes. Roots may extend more than 35 feet (10.6 m) laterally and vertically more than 6 feet (1.8 m). Rhizomes range from 0.4 to 0.8 inch (1-2 cm) in diameter.
Generally, chokecherry plants leaf out in spring to early summer and flower 1 to 3 weeks later, with fruits maturing in late summer to fall. Fruits dehisce soon after maturity.
