Prunus virginiana, commonly called bitter-berry, chokecherry, Virginia bird cherry, and western chokecherry, is a species of bird cherry native to North America; the natural historic range of P. virginiana includes most of Canada, most of the United States (including Alaska but excluding some states in the Southeast) and northern Mexico. Chokecherry is a suckering shrub or small tree growing to 1–6 m (3 ft 3 in–19 ft 8 in) tall, rarely to 10 m (32 ft 10 in). The leaves are oval, 2.5–9 cm (1–3 1⁄2 in) long and 1.2–5 cm (1–2 in) wide, with a serrated margin. The flowers are produced in racemes 4–11 cm (1 1⁄2–4 1⁄4 in) long in late spring. They produce a strong heady aroma which some people find to be unpleasantly smelly, while others perceive them to have an aphrodisiac-like effect. The fruits are about 6–14 mm in diameter, range in color from bright red to black, and possess a very astringent taste, being both somewhat sour and somewhat bitter. When very ripe, the “berries” (actually drupes) are dark in color and less astringent and sweeter than when red and unripe (Wikipedia).
