Heteranthera zosterifolia from South America is an extremely beautiful plant which forms a lot of side shoots and thus quickly forms a bushy plant group. Stems can become 30-50 cm tall and 6-12 cm wide. In strong light growth is intensive, and the plant must be pruned before it becomes so compact that no light reaches the lower leaves. Water roots often form on the stem. In open aquariums it forms small blue flowers if some shoots are allowed to spread on the surface.

Note that with this tissue cultured plant the liquid nutrient solution is often very dark brown or blue – this does not mean the plant in unhealthy but just what it’s grown in and part of the production process.
