Dennerle Hydrocotyle verticillata
A highly ornamental pennywort with umbrella-like leaves, suitable for the foreground to midground. It grows slowly compared with H. leucocephala and H. tripartita and prefers water temperatures on the cooler side. We found some fantastic stands of it in the shallows of the Rio Sucuri in Brazil. There the water temperature was 23°C, and it was crystal clear and had a high concentration of CO2. Hydrocotyle verticillata looks very natural in the middle of a Hemianthus carpet with the little umbrellas peeking out.
