This Far East species is something of a mystery, whose description isn’t easy to find in the literature. Nevertheless, it has long been known in its native range. It – and other similar plum species – has been grown from seeds by the Chinese and Koreans especially in the Ussuri and the Yalu River valley areas. It resembles the Japanese plum (P. salicina). The American have taken into cultivation a Japanese plum variety called ‘Mandshurica’, whose description is very close to P. ussuriensis.
