Hygrophila polysperma Rosanervig Tropica

Hygrophila polysperma 'Rosanervig' is normally an undemanding plant.
It may suddenly develop shoots that are entirely green. Remove these to keep the distinctive pink, marbled leaves. If you want deep-pink leaves, you must provide intensive light. Stems become 20-40 cm tall and 5-8 cm wide.
The distinctive colouring of the pale leaf ribs is probably caused by a virus which prevents chlorophyll from being produced in the cells around the leaf ribs, making them white. However, this virus does not affect other plants in the aquarium.
