Plant Needs
Sunlight
Requires full sun to maintain vibrant silvery foliage; tolerates partial shade but may lose color intensity in low light
Watering
Water deeply when the top 5 cm of soil is dry; avoid overwatering to prevent root rot, especially in heavy clay soils
Temperature
Hardy to light frosts (down to -5°C); protect from extreme heat above 38°C to prevent foliage scorch
Characteristics
- Leaf: Round, silvery-blue juvenile leaves (primary ornamental trait); adult leaves are lanceolate, dull green
- Flower: Creamy-white, fluffy umbel clusters with prominent stamens
- Stem: Smooth, pale grey bark that sheds in thin, papery strips
Care Guide
Watering
Keep soil evenly moist but not waterlogged; increase watering frequency during hot, dry spells
Fertilization
Diluted balanced liquid fertilizer once every 2 months. Avoid over-fertilizing, as excessive nutrients can dull foliage color
Banana peel compost tea：Compost banana peels for 2–3 weeks to break down nutrients; steep in water for 24 hours, dilute 1:20 with water for root drenching; avoid using raw peels to prevent pest infestationsPruning
- Prune heavily in late winter to encourage new juvenile foliage (the primary ornamental feature)
- Remove dead, damaged, or crossing branches to improve airflow and reduce disease risk
- Shape the shrub in early spring to maintain a compact, bushy form
- Avoid pruning during hot summer months to prevent stress and foliage scorch
