Plum

Plum is a familiar name for a surprisingly diverse group of stone fruits in the genus Prunus. There is no single wild ancestor or homeland for every cultivated plum. The two principal commercial groups—European plums and Japanese plums—arose from different species and regions.

The European plum, Prunus domestica, is generally associated with western Eurasia. Its precise ancestry remains debated, but it likely developed through ancient hybridization and selection involving Eurasian plum relatives. Farmers gradually produced forms suited to fresh eating, drying into prunes, preserving, and fermentation.

The Japanese plum, Prunus salicina, is native to China and was cultivated there long before becoming closely associated with Japan. Japanese growers refined important varieties, and plant breeders later crossed them with other plum species. Those improved fruits reached California in the nineteenth century and helped establish the large, colorful plums now common in supermarkets.

China remains the leading plum-producing country, while southeastern Europe, Turkey, Chile, and California are also important growing areas. North America has native plum species of its own, some still harvested or used in breeding. The modern plum aisle therefore represents several botanical histories brought together under one simple name.
