Plant Needs
Sunlight
Full sun to partial shade; full sun exposure enhances the intensity of the purple foliage color
Watering
Water deeply once weekly during dry periods; allow the top 5–10 cm of soil to dry between waterings to prevent root rot
Temperature
Hardy to -15°C; tolerates warm summer temperatures up to 35°C, with young plants requiring light frost protection in extreme cold
Characteristics
- Leaf: Oval to obovate leaves, deep purple-red throughout the growing season, with finely serrated margins
- Flower: Fragrant white to pale pink five-petaled blooms, clustered along bare stems before leaf emergence
- Stem/Bark: Smooth light brown bark, developing subtle vertical fissures as the tree matures
Care Guide
Watering
Water deeply when the top 5–10 cm of soil feels dry; avoid wetting foliage to reduce fungal disease risk
Fertilization
Apply a balanced slow-release fertilizer once in early spring to support new growth. Do not over-fertilize, as this can dilute the purple foliage color
Eggshell powder top-dress：Crush dried eggshells into a fine powder; sprinkle 1–2 tablespoons around the base of the tree in early spring and late autumn, mixing lightly into the topsoilPruning
- Prune immediately after flowering to maintain a rounded canopy shape and remove spent blooms
- Thin out dead, diseased, or crossing branches to improve air circulation and reduce disease risk
- Trim overcrowded inner branches to enhance light penetration and preserve foliage color intensity
- Avoid heavy pruning in late summer, as new growth may be damaged by winter frost
