Heteranthera zosterifoliaHeteranthera 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
