About
European Frogbit
European frogbit is a free-floating annual aquatic herb in the Frog’s Bit family. It invades shallow, quiet, or slow-moving water; edges of lakes, rivers, and streams;; swamps, marshes, and ditches. European frogbit forms large colonies of dense, floating mats that can dramatically affect native aquatic life and limit recreational activities.
