The '''Chokecherry''' (''Prunus virginiana'') is a species of [[bird cherry (subgenus)|bird cherry]] (''Prunus'' subgenus ''Padus'') native to [[North America]], where it is found almost throughout the continent except for the deep south and the far north. It is a suckering [[shrub]] or small [[tree]] growing to 5 m tall. The [[leaf|leaves]] are oval, 3-10 cm long, with a coarsely serrated margin. The [[flower]]s are produced in [[raceme]]s of 15-30 in late spring (well after leaf emergence). The [[fruit]] are about 1 cm diameter, bright red, with a very [[astringent]], sour taste. Like chokeberries, chokecherries are very high in antioxidant pigment compounds, like anthocyanins.
There are two varieties:
*'''Common Chokecherry''' ''Prunus virginiana'' var. ''virginiana''. Eastern North America. Leaves hairless underneath or downy only in the vein axils.
*'''Western Chokecherry''' ''Prunus virginiana'' var. ''demissa''. Western North America. Leaves downy underneath.

The wild Chokecherry is often considered a pest, as it is a host for the [[tent caterpillar]], a threat to other fruit plants. However, there are more appreciated [[cultivar]]s of the chokecherry, such as 'Goertz', which has a non-astringent, and therefore palatable, fruit. Research is being done at the [[University of Saskatchewan]] to find and create new cultivars to increase production and processing [http://www.agr.gov.sk.ca/afif/Projects/19960373.pdf].
Chokecherry is closely related to the [[Black Cherry]] (''Prunus serotina'') of eastern North America; it is most readily distinguished from that by its smaller size (Black Cherry can reach 30 m tall), smaller leaves, and red (not black) ripe fruit.
The name chokecherry has also been used (as 'Amur Chokecherry') for the related [[Manchurian Cherry]] or Amur Cherry (''Prunus maackii'').
Chokecherry is toxic to [[horse]]s, especially after the leaves have wilted (such as after a frost or after branches have been broken) because wilting releases [[cyanide]] and makes the plant sweet. About 5-10 kg of foliage can be fatal. Symptoms of a horse that has been poisoned include heavy breathing, agitation, and weakness. The leaves of the chokecherry serve as food for [[caterpillar]]s of various [[Lepidoptera]]. See [[List of Lepidoptera which feed on Prunus|List of Lepidoptera which feed on ''Prunus'']].
----
The [[Chokeberry|chokeberries]], genus ''Aronia'', are often mistakenly called [[Chokecherry|chokecherries]] . This naming confusion is easy to understand considering there is a cultivar of the chokecherry ''Prunus virginiana'' 'Melanocarpa' [http://www.msue.msu.edu/msue/imp/modzz/00001191.html], [http://www.laspilitas.com/plants/545.htm], and a species of chokeberry named ''[[Black Chokeberry|Aronia melanocarpa]]'' [http://www.msue.msu.edu/msue/imp/modzz/00000145.html].
