Japanese
The Santa Rosa plum is a legendary backyard fruit tree with a story as rich as its flavor. Introduced in 1906 by legendary horticulturist Luther Burbank in his Santa Rosa, California home, this Japanese plum variety has become a favorite among home gardeners and farmers' market growers for more than a century. It reaches 18, 20 feet tall at maturity and produces large red fruits with a sweet, slightly tart taste that earned it a place in orchards across hardiness zones 5, 9. What sets Santa Rosa apart is its relatively fast path to bearing fruit compared to other plum varieties, beginning to produce in as few as 3, 6 years rather than waiting a decade or more.

Santa Rosa plums are prized for their stunning ornamental presence, with pink and white blooms in July that announce the season. The deep purple-red fruits are impressively large and arrive earlier than many other plum types, making this variety especially appealing to impatient gardeners. The balance of sweetness and slight tartness in the flavor creates a complexity that works equally well eaten fresh from the tree or preserved for later use.
Santa Rosa plums are primarily grown for fresh eating, where their sweet-tart balance shines when picked ripe and enjoyed straight from the tree. The fruits are also excellent for preserving through jams, jellies, and canning, where their natural pectin and flavor complexity create rich preserves. Home gardeners often use them for baking into pies and tarts, or simply slicing into breakfast bowls and desserts.
Santa Rosa plum trees are typically purchased as dormant bare-root or container-grown specimens from nurseries rather than started from seed. Plant in early spring while trees are still dormant, spacing them 20 feet apart. Container-grown trees can also be planted in fall in warmer zones. Dig a hole as deep as the root ball and twice as wide, backfill with amended soil, and water thoroughly to settle the soil.
Santa Rosa plums are ready to harvest in mid to late summer, typically around 3, 6 years after planting. Pick fruits when they yield slightly to gentle pressure and display their full deep purple-red color. The fruits will continue to soften slightly after picking if harvested just before peak ripeness, or you can leave them on the tree longer for maximum sweetness. Gently twist or cut the plums from branches to avoid bruising.

“Luther Burbank, one of America's most prolific plant breeders, developed the Santa Rosa plum at his experimental gardens in Santa Rosa, California, introducing it to the world in 1906. Burbank worked with Japanese plum genetics to create a variety that combined superior flavor with practical growing characteristics for North American orchardists. Unlike many commercial plum varieties that dominate the global fruit trade, Santa Rosa plums have remained relatively uncommon in large-scale commercial production, which paradoxically has preserved their reputation as a special-occasion fruit found at farmers' markets and home gardens rather than supermarket shelves.”
