Plant Needs
Sunlight
Thrives in full sun for maximum blooming; tolerates partial shade in hot, arid climates; avoid deep shade which reduces flower production
Watering
Water when the top 2–3 cm of soil feels dry; avoid overwatering to prevent root rot, as the plant is moderately drought-tolerant
Temperature
Optimal growth at 18–27℃; protect from frost below 10℃, as cold temperatures will damage foliage and stems
Characteristics
- Leaf: Glossy, oblong dark green leaves with pale midribs; arranged oppositely on stems
- Flower: Five-petaled trumpet-shaped blooms in pink, white, or pale lavender; center often has a darker contrasting eye
- Stem: Slender, branching green stems that exude milky white sap when broken
Care Guide
Watering
Keep soil evenly moist but not waterlogged; increase frequency during extended heatwaves
Fertilization
Feed with diluted balanced fertilizer every 2 weeks. Avoid over-fertilizing, as this can reduce flower production and cause leggy growth
Banana peel tea：Chop 2–3 banana peels and soak in 1L of water for 3 days; strain solids and dilute the tea 1:2 with water before applying to soil to avoid nutrient burnPruning
- Pinch growing tips when plants reach 10–15 cm tall to encourage bushy, compact growth and more flower buds
- Deadhead spent blooms regularly to prolong the flowering period and prevent self-seeding
- Trim leggy or frost-damaged stems in early spring to refresh the plant’s shape
- Remove yellowing or diseased leaves to improve airflow and reduce pest risk
