“Araguaia” is a river system in Brazil and it is under this name that the plant has become known. There are many signs, however, that the plant is a Hygrophila lancea from Japan and Hong Kong.

The stem becomes 10-20 cm tall and 6-15 cm wide. It has compact, tight-sitting leaves and grows branches easily. Pinching of the stems maintains a bushy look. The colour is reddish brown to purple, promoted by good growth conditions. The growth rate is average for a Hygrophila. 

can be planted in substrate or attached to wood/rock
