Japanese
Satsuma plum is a Japanese heirloom introduced by Luther Burbank in the late 1800s, prized for its deep crimson flesh and rich, complex flavor. This small to medium fruit wears a distinctive mottled maroon skin and thrives in warm climates, hardy in zones 5 through 10 (though some sources report zone 9 as the upper limit). The tree reaches 12 to 16 feet tall at maturity and begins fruiting within three years, blooming in early to mid-summer depending on your location. Often called a blood plum for its striking interior, Satsuma excels at the table fresh or transformed into preserves and baked goods.

The Satsuma's deep red, juicy flesh and mottled maroon exterior make it instantly recognizable among plums. Luther Burbank's careful selection bred a tree that tolerates heat and low chill hours beautifully, expanding plum growing into regions where other varieties struggle. Semi-dwarf when grafted on Citation rootstock, it produces abundant fruit while staying manageable, and its early white blooms add genuine ornamental charm before the edible treasure arrives.
Fresh eating showcases the Satsuma's sweet, mild complexity straight from the tree. Its firm, meaty flesh makes it exceptional for cooking and sauce production, where the deep color and subtle tartness contribute depth to preserves, jams, and compotes. The fruit excels in baked desserts, from crisps to tarts, where its natural pectin and flavor concentrate beautifully. Some growers train these trees as espaliers, combining productivity with ornamental appeal along walls or fences.
Plant bare-root trees in late winter while dormant, or container-grown trees in spring after frost danger passes. Space trees 12 to 15 feet apart if planting multiples, though semi-dwarf grafted specimens may be planted closer. Dig a hole slightly wider than the root ball, position the graft union 1 to 2 inches above soil level, and backfill with native soil mixed lightly with compost. Water thoroughly to settle soil and eliminate air pockets.
Satsuma plums ripen from mid-summer into early autumn, depending on your location. The fruit develops its deep maroon color when fully ripe and yields slightly to gentle pressure but should not be mushy. Pick plums when they slip easily from the branch with a light twist, though they will continue to soften for a few days in a cool room if harvested slightly early. Commercial orchardists often pick selectively over several weeks rather than stripping the tree at once, extending the harvest window.
Prune Satsuma in late winter while dormant to establish an open, vase-shaped canopy that encourages air circulation and sunlight penetration. Remove crossing branches, inward-facing growth, and any dead or diseased wood. For espalier training, begin tying young branches to support structures in spring and summer, pruning side shoots to 2 to 3 leaves beyond the main framework. Mature trees need only light maintenance pruning to remove crowded fruiting wood and maintain shape.

“Satsuma plum arrived in American gardens through Luther Burbank's innovative breeding program in the late 1880s, brought to California directly from Japan. Burbank recognized the variety's potential for warm-climate gardeners and its remarkable ability to fruit with minimal winter chill hours, a critical trait for regions that rarely experience hard freezes. This cultivar represents a deliberate effort to adapt Japanese genetics to North American growing conditions, making it a bridge between two horticultural traditions. The name occasionally sparks confusion with the mandarin orange that shares it, yet the Satsuma plum has earned its own devoted following among fruit gardeners for over a century.”
