The Santa Rosa Japanese plum (Prunus salicina 'Santa Rosa') is a highly popular, versatile, and self-fertile fruit tree known for its large, purplish-red plums with amber flesh. Introduced in 1906, it features a sweet-tart flavor, making it excellent for fresh eating, canning, and jelly. These trees thrive in full sun and are hardy in USDA Zones 5-9.
