European Frogbit

European frog-bit grows in shallow, quiet, or slow-moving water; along the edges of lakes, rivers, and streams; and in swamps, marshes, and ditches. It is a free-floating, stoloniferous aquatic plant that can grow to form dense floating mats of interlocking plants. The leaves are leathery, measure 0.5-2.5” across, and are round to heart-shaped. The flower has three white petals and the stem has horizontal runners that produce new plants.

The dense growth form of this species can get caught in boat motors, affect fish and waterfowl movement, and decrease oxygen levels in water as plants decompose.

European frog-bit is extremely difficult and costly to control, and its ability to form new plants vegetatively has allowed it to spread and proliferate quickly. The plant has been declared a noxious weed in parts of the United States.
