Plant Needs
Sunlight
Needs moderate to bright indirect submerged light; avoid prolonged direct sun that triggers excessive algae growth
Watering
Aquatic plant; requires consistent, clean freshwater with gentle water flow to prevent stagnation and nutrient buildup
Temperature
Thrives in cool to temperate freshwater; avoid extreme fluctuations above 30°C or below 0°C
Characteristics
- Leaf: Submerged leaves are finely divided, feather-like whorls; emergent leaves are smaller, linear, and less divided
- Flower: Tiny, four-petaled white flowers on emergent upright spikes
- Stem: Slender, branching submerged stems that root at nodes for anchorage
Care Guide
Watering
Maintain stable water level; perform 20% weekly water changes to refresh nutrients
Fertilization
Diluted aquatic fertilizer every 2 weeks. Use low-nitrogen aquatic fertilizer to prevent excessive algae growth
Established aquarium water runoff：Use water from weekly aquarium water changes to provide gentle, natural nutrients; avoid over-application to prevent algae bloomsPruning
- Trim overgrown submerged stems to prevent overcrowding and improve water circulation
- Remove spent emergent flower spikes after blooming to redirect energy to foliage growth
- Thin dense whorls of leaves to ensure light reaches lower submerged stems
