Hydrocotyle verticillata is a common weed found throughout the warmer regions of the Americas, growing in areas ranging from poorly-drained soils to shallow water. It differs from the more commonly available H. leucocephala in that the leaves are entire (like a miniature parasol) and not incised (cut) at the base. There seem to be many H. verticillata look-a-likes in the trade that grow significantly taller. The true H. verticillata is uncommon in the U.S. trade, although both Tropica and Oriental Aquariums grow it.
H. verticillata is not too difficult to maintain in the aquarium. The most important factor is lighting, as the height of this plant will be determined by lighting intensity. The stronger the lighting, the shorter this plant will be. Otherwise, this plant is not too fussy about CO2 or fertilization, although a well balanced nutrient regime and CO2 injection do greatly enhance growth and overall health.
