Water Lettuce in India
This floating aquatic plant, known as अन्तरगंगा Antarganga (Hindi), ஆகாசத்தாமரை Akasha-T-Tamarai (Tamil), అంతరతామర Antara-Tamara (Telugu), ಅಂತರಗಂಗೆ Antaragange (Kannada), ആകാശത്താമര Akasathamara (Malayalam), आकाशमूली Akashamuli (Marathi), is a common sight on ponds and slow-moving water. Pistia stratiotes is found across Kerala, West Bengal, Karnataka, Tamil Nadu, Maharashtra, NCT of Delhi, often forming dense mats on still water.
Uses
It's sometimes grown in ornamental ponds and aquariums for its rosette shape, and it can help take up excess nutrients from water, though it can also spread aggressively and clog waterways if not managed.
How to Identify Water Lettuce
A floating rosette of soft, pale green, velvety, ribbed leaves with no true stem, trailing feathery roots below the waterline. Flowers are tiny and inconspicuous, tucked at the base of the leaf rosette.

- It can be — while attractive and useful for ornamental ponds in small numbers, it reproduces quickly and can form dense mats that clog waterways if left unchecked.
- Does it have real roots in the soil?
- No — it floats freely on the water's surface, with feathery roots trailing directly into the water rather than anchored in soil.
