Hygrophila glabra

The quite undemanding Broad-leaved Giant Water Lily Hygrophila corymbosa "glabra" from Southeast Asia is particularly suitable as background planting for large aquariums. The Broad-leaved Giant Water Lily is well suited for group planting and contrasts wonderfully with more finely structured plants. However, the individual plants should not be too close together so that the lower leaves also get light. Underwater, the broad leaves are bright light green. The upper leaves often show reddish-brown leaf veins.

Broad-leaved Giant Water Lily grows 5 to 10 inches a week. If not pruned, it will grow above the water level and then bloom with purple flowers. So it is excellent for open aquariums as well.

If the Broad-leaved Giant Water Lily is pruned, new side shoots will form.
The cut parts of the plant can be planted without problems and will take root after a short time.

Giant hygrophytes remove excess nutrients (such as nitrate and phosphate) from the water. As a result, algae lose their food base. Bearded and brush algae have no chance to spread.
