Prunus virginiana
Chokecherries are very high in antioxidants, sharing this trait with chokeberries. This does contribute to confusion between the two. The wild chokeberry is often considered a weed, since it hosts the tent caterpillar. This caterpillar eats tree leaves, robbing trees of energy and heightening the chance that they die. Often people enjoy the cultivars of the plant,  such as "Canada Red" and "Schubert". Both have purple leaves when mature and "Goertz", another cultivar, has a palatable taste in it's fruit. The chokecherry is closely related to the well-known black cherry of eastern North America. The name chokecherry is also used for the related Manchurian cherry, or Amur chokeberry.
