A popular decorative, oxygenating and water filtering plant. 

The submerged leaves grow in whorls of 4 to 8, up to 4 cm long and are produced on trailing stems to 2 m or more long.  Prefers full sun in deeper water to 1m, but will grow in part-shade in shallow water.

A good habitat plant providing food and shelter for aquatic life.

Occasionally brush leaves gently to remove debris and trim back excess growth.
