Plant Needs
Sunlight
Full sun to partial shade; full sun promotes the brightest crimson new foliage, while partial shade prevents leaf scorch in hot, arid climates
Watering
Water deeply when the top 5–7 cm of soil is dry; avoid overwatering to prevent root rot and fungal leaf spot
Temperature
Hardy to -10°C; protect young plants from extreme frost; tolerates warm summer temperatures with consistent moisture
Characteristics
- Leaf: New growth is bright crimson red; mature leaves are glossy dark green, elliptical, 5–10 cm long
- Flower: Dense clusters of small white five-petaled blossoms with a pungent, musky fragrance
- Stem: Woody brown stems with smooth young bark, developing subtle texture with age
Care Guide
Watering
Keep soil consistently moist but not waterlogged; increase watering frequency during extended heatwaves
Fertilization
Apply balanced slow-release fertilizer once to support new growth. Avoid over-fertilizing, as excess nitrogen can reduce red foliage intensity
Composted eggshell powder：Crush dried eggshells into a fine powder; mix 1–2 tablespoons into the top 2 cm of soil around the base of the shrub to boost soil calcium and maintain neutral pHPruning
- Prune immediately after flowering to maintain hedge shape and encourage new crimson foliage growth
- Remove dead, diseased, or overcrowded branches to improve airflow and reduce fungal disease risk
- Thin dense growth to allow light penetration to inner foliage
- Avoid heavy pruning in late autumn, as new growth may be damaged by winter frost
