Plant Needs
Sunlight
Full sun to partial shade; requires 6+ hours of direct sunlight daily for consistent blooming; avoid dense overhead shade
Watering
Requires consistent, still freshwater; maintain water depth of 30–90 cm to support rhizome growth and leaf floating
Temperature
Thrives in 18–28°C; tolerates brief dips to 10°C but may stop growing below 15°C; protect rhizomes from freezing in cold climates
Characteristics
- Leaf: Round, waxy floating leaves with a deep notch; green upper surface, purplish underside
- Flower: Showy white to pale pink blooms, 10–15 cm wide; fragrant, opening by day and closing at night
- Rhizome: Thick, fleshy underwater rhizome anchoring in aquatic substrate
Care Guide
Watering
Keep water level consistent, ensuring rhizomes are fully submerged; avoid rapid temperature fluctuations from water changes
Fertilization
Diluted aquatic fertilizer applied to substrate. Use slow-release aquatic fertilizer tablets to avoid algae blooms from excess nutrients
Composted banana peel tea：Steep fully composted banana peels in water for 3 days; dilute 1:20 and apply directly to pond water; avoid raw peels to prevent algae growth and odorPruning
- Remove yellowing leaves and spent blooms to maintain water clarity and prevent organic buildup
- Thin overcrowded rhizomes in spring to reduce competition for nutrients and light
- Trim floating leaves to allow light penetration to submerged aquatic plants
Toxicity
Warning: this plant may be toxic.
