​Hygrophila polysperma 'Rosanervig

Hygrophila polysperma 'Rosanervig' is not a demanding plant, but if you really want to fully enjoy the characteristic pink buds, make sure you provide enough light. The stems grow to about 20-40 cm long and 5-8 cm wide. The striking light leaf ribs are probably caused by a virus that is completely harmless to other plants and animals. This prevents chlorophyll from being produced in the cells around the leaf ribs. This keeps the leaf ribs white.
