An East Asian plum species that's the basis for most modern American supermarket plums — large, juicy, with red or yellow skin and easily separated flesh from a small pit.
Actually Chinese, not Japanese
Despite the name, Prunus salicina is native to China, not Japan. The “Japanese” label stuck because Western horticulturists in the 19th century encountered the species via Japan, where it had been cultivated for centuries.
Confusingly, the related Prunus mume (used for Japanese umeboshi pickled plums and umeshu plum wine) is a separate species — actually a closer relative of the apricot.
Luther Burbank’s American empire
The Japanese plum was transformed into a global crop by Luther Burbank in California in the 1880s-1900s. He imported seedlings from Japan and bred dozens of new cultivars adapted to American conditions, with bigger fruit, better flavor, and longer shelf life.
Burbank’s varieties — particularly Santa Rosa, Methley, and Burbank — became the basis for the modern global commercial plum industry. They’re now grown across California, Chile, South Africa, Spain, and Australia.
Different from European plum
The Japanese plum and the European plum (Prunus domestica, the source of prunes and damsons) are distinct species with very different fruit:
- Japanese plum — round to heart-shaped, juicy, freestone, eaten fresh
- European plum — oval, denser flesh, often clingstone, more for cooking and drying
Most American supermarket “plums” are Japanese plum varieties; “prunes” are dried European plums.
The umeshu confusion
When Westerners say “Japanese plum wine” (umeshu), they often think of the same Japanese plum species — but it’s not. Umeshu is made from ume, Prunus mume, which is technically a Chinese apricot species, not a true plum.
The result: traditional Japanese plum products (umeshu, umeboshi) and Japanese plum the supermarket fruit are botanically different fruits with overlapping naming.
