Aronia melanocarpa, the black chokeberry, is a deciduous shrub native to the eastern U.S. which produces dark, astringent berries. A good addition to hedges, it does well in full sun or dappled shade and along forest edges. It grows to an average of 8' tall and up to 9' wide.
The berries are produced in clusters and persist into winter (and become tastier after a frost or two) providing forage for wildlife and "winter interest" in the garden. The berries are also high in pectin, making the fruit a good addition for preserves.
