Plant Needs
Sunlight
Full sun to partial shade; full sun promotes maximum flowering, while partial shade prevents leaf scorch in extreme heat
Watering
Water deeply when the top 2–3 cm of soil feels dry; avoid overwatering to prevent root rot and fungal growth
Temperature
Thrives in warm temperate to tropical conditions; protect from frost below 10°C to prevent leaf damage and dieback
Characteristics
- Leaf: Opposite, ovate to lanceolate leaves with serrated margins; aromatic when crushed
- Flower: Dense umbel-like clusters of tiny tubular blooms, shifting color from pale pink to deep magenta as they mature
- Stem: Woody, branching stems with fine silvery pubescence
Care Guide
Watering
Keep soil consistently moist but not waterlogged; increase watering frequency during prolonged hot, dry spells
Fertilization
Diluted balanced liquid fertilizer every 2 weeks. Avoid over-fertilization, as excessive nitrogen may reduce flower production
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, and apply as a root drench to prevent nutrient burnPruning
- Deadhead spent flower clusters regularly to encourage continuous blooming throughout the growing season
- Prune back overgrown or leggy branches in early spring to maintain a compact, rounded shape
- Remove diseased, damaged, or yellowing stems to improve airflow and reduce pest and disease risk
