About

Prunus maackii, commonly called the Manchurian cherry or Amur chokecherry, is a species of cherry native to Korea and both banks of the Amur River, in Manchuria in northeastern China, and Amur Oblast and Primorye in southeastern Russia. It used to be considered a species of Prunus subg. Padus, but both morphological and molecular studies indicate it belongs to Prunus subg. Cerasus.
