Hydrocotyle verticillata

Whorled Pennywort, Whorled Marshpennywort, Shield Pennywort, Water Pennywort

A low-growing semi-aquatic herb with round, glossy leaves on slender stems that look like tiny lily pads. The leaves are peltate, meaning the stem attaches to the centre of the leaf rather than the edge. Native to wetlands across the Americas and parts of Africa, it spreads quickly via stolons and underground runners, forming dense mats of coin-shaped foliage. It grows well submerged in aquaria, emergent in paludariums, or terrestrially in moist closed terrariums.
