Lilaeopsis Brasiliensis

Gratiola Viscidula is a relatively new aquatic plant in the hobby that hails from North America. Its leaves make the plant easily recognized and are almost thorn-like with a light green coloration. Gratiola Viscidula is an easy aquarium plant so long as clean water and good lighting are provided. It's also a slow grower, but in time can be used as a midground plant or even a foreground plant if kept trimmed low enough.
