Where does Water Clover Grow?
Water clover can be found in the mud or sand along sunny spots at the edges of swamps, marshes, ditches, streams, ponds and lakes.

Water clover can be an aggressive invader of ponds. If colonies cover the surface of the water, then oxygen depletion and fish kills can occur. These plants should be controlled before they cover the entire surface of the pond.
