This Hygrophila from Thailand develops under water light green and densely set, lanceolate leaves. The shoots are 15-40+ cm tall and 10-15 cm wide. In open aquariums Hygrophila corymbosa 'Siamensis' grows easily above the water surface, where it forms blue-green leaves and small blue flowers. It grows fast and the shoots must be pinched out regularly if you want to keep the plant under water. An extremely hardy plant, suitable for beginners.
