Santa Rosa Plum

Santa Rosa Plum (Prunus salicina 'Santa Rosa')

Santa Rosa Plum (Prunus salicina 'Santa Rosa') is one of the most popular and widely grown Japanese plum varieties, cherished for its large, flavorful fruit and showy spring bloom. Developed by famed horticulturist Luther Burbank in the early 20th century, this self-fertile cultivar produces juicy, reddish-purple plums with amber flesh and a sweet-tart flavor that's excellent for fresh eating, baking, and preserves. With both ornamental appeal and fruiting power, it's a favorite in home orchards and edible landscapes.

Distinctive Features

'Santa Rosa' is known for its vigorous growth, reliable yields, and attractive fruit. Fragrant white flowers blanket the tree in early spring, followed by round, medium to large plums that ripen in mid to late summer. The skin is reddish-purple with a dusty bloom, while the interior is golden-yellow with streaks of red. Fruit is clingstone, juicy, and aromatic. Mature trees typically reach 15 to 20 feet tall and wide but can be maintained at a smaller size with pruning.

Growing Conditions

• Sun Exposure: Full sun is essential for maximum fruit production and flavor.
• Soil: Well-drained, moderately fertile soil; tolerates sandy or loamy conditions.
• Water: Moderate; regular deep watering during the growing season promotes strong yields.
• Humidity: Performs best in areas with dry summer air; avoid low-lying, humid sites to reduce disease pressure.
• USDA Hardiness Zones: 5-9; reliably hardy and productive in a wide range of climates.

Ideal Uses

• Edible Gardens: A productive and attractive fruit tree for backyard orchards.
• Focal Point Plantings: Spring blooms and colorful fruit add beauty to edible landscapes.
• Containers (young trees): Can be grown in large pots when pruned for size control.
• Mixed Borders: Combines ornamental and edible qualities in one plant.
• Pollinator Gardens: Early spring blossoms support bees and beneficial insects.

Low Maintenance Care

Santa Rosa Plum is easy to grow with basic care. Its self-fertile nature means a single tree can produce fruit, though planting another Japanese plum nearby may improve yields.

• Watering: Water deeply and consistently during flowering and fruit development; reduce frequency in fall.
• Pruning: Prune in winter to maintain shape and encourage light penetration; thin fruit in early summer to improve quality.
• Fertilizing: Apply a balanced fertilizer in early spring; avoid overfeeding to prevent excessive vegetative growth.
• Pest and Disease Resistance: Susceptible to aphids, leaf curl, and brown rot; monitor regularly and manage with cultural practices.
• Winter Care: No special protection needed in Zones 5-9; mulch helps regulate soil moisture and temperature.
