Care

Aponogeton undulatus is a submerged bulb plant from India, Bangladesh, Myanmar and Sri Lanka, with very pale green leaves 10–15 cm long on stalks of similar length, with wavy edges. The true species makes no floating leaves, though some hybrids sold under the name do. Some taxonomists use the name Aponogeton stachyosporus. It is a popular specimen plant for the midground. It tolerates most water conditions and prefers bright light but grows in part shade. Some plants rest in winter and can be kept cooler for a few months, while others grow on. Water figures are our estimate, not from the sources. Sources: Wikipedia (en.wikipedia.org/wiki/Aponogetonundulatus); Wikipedia, List of freshwater aquarium plant species. Checked October 2026.

Breeding

Hand-pollinate flowers with a fine brush; sow seed on sand or very fine gravel under shallow water.

Compatibility and tank mates

Snails and plant-eating fish (goldfish, large cichlids, silver dollars) may damage the soft leaves. Best with peaceful tropical community fish that do not dig up the bulb.
