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. Leaves often become black on the back. 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. Those are easily cut and replanted.
In open aquariums, it forms small blue flowers if some shoots are allowed to spread on the surface.
