Frogbit is an attractive aquatic plant that floats on the surface of ponds, lakes and still waterways. Looking like a small water-lily, it is in bloom during July and August. In the winter, it becomes dormant and its buds are buried in the mud at the bottom of the pond. When it grows back, it provides shelter for tadpoles, small fish and dragonfly larvae.
