Prunus salicina

Background

Introduced in 1906-1907 by Luther Burbank in Santa Rosa, California, from Japanese and European plum crosses; one of the earliest commercial plum hybrids. It became one of the most widely planted plums in the world, and Japanese plum ripening times are still commonly counted relative to Santa Rosa.

Distinguishing traits

Large dark reddish-purple fruit with fragrant amber-yellow flesh, sweet-tart and juicy; showy white-pink spring bloom; self-fertile, vigorous, and early to bear. Early-mid season harvest, June-July.
