Black Chokecherry (Prunus virginiana)

Choke Cherry (Prunus virginiana) is a species in the Rosaceae (Rose) family, in the Bird Cherry (Padus) subgenus. It is native to North America where it is found almost throughout the continent except for the deep south and the far north. The plant is widespread in California, particularly in the mountains. It is a suckering shrub or small tree growing to 5 meter tall. The leaves are oval, 3-10 centimeter long, with a coarsely serrated margin. It is deciduous, and the leaves provide some fall color. The flowers are produced in racemes of 15-30 inches late spring (well after leaf emergence). The fruits are about 1 centimeter diameter, range in color from bright red to black. Although they are said to be edible, they contain small amounts of cyanide, especially when unripe. The very ripe berries are dark in color, less astringent, and contain less cyanide. Despite the potential toxicity, the fruits were valued by many Native people.
