Plant Needs
Sunlight
Full sun to partial shade; full sun promotes optimal fruiting, while partial shade prevents leaf scorch in hot inland climates
Watering
Water deeply when the top 5 cm of soil is dry; drought tolerant once established, with reduced watering needs in mature plants
Temperature
Hardy to USDA zones 6–9; tolerates mild winter frosts and summer heat up to 35°C
Characteristics
- Leaf: Ovate to subcordate, 2–7 cm long, serrated margins, glossy green above, pale beneath
- Flower: Clusters of 2–5 fragrant, white 5-petaled blooms
- Fruit: Round, red to purple edible plum, 1–2 cm diameter when ripe
- Stem: Slender gray-brown branches with small, sharp thorns
Care Guide
Watering
Water regularly during fruiting season to prevent premature fruit drop
Fertilization
Apply balanced organic fertilizer once to support new growth and fruiting. Avoid high-nitrogen fertilizers to prevent excessive leaf growth at the expense of fruit production
Eggshell powder topdress：Crush dried eggshells into fine powder; sprinkle 1–2 tbsp around the base of the plant and water in to release calcium graduallyPruning
- Prune dead, diseased, or crossed branches in late winter before new growth emerges
- Thin crowded branches to improve airflow and sunlight penetration for better fruiting
- Remove suckers growing from the base to maintain the desired shrub or tree shape
- Trim back overgrown stems after fruiting to encourage compact, productive new growth
Toxicity
Warning: this plant may be toxic.

Humans: Flesh of ripe plums is safe; seeds contain cyanogenic glycosides, which are toxic if ingested in large quantities
Garden Uses & Culture
Culture: N/A
Usage: Edible fruit for jams, jellies, and fresh eating; ornamental native garden plant for spring blooms
