In the State of Maine it is now illegal to sell, propagate, or introduce to Maine waters these eleven invasive aquatic plants. These plants are aggressive growers. If they are introduced into our freshwaters they will become a serious nuisance.

Currently, five of these plants have been found in Maine waterbodies -- *Variable-leaf Milfoil, Hydrilla, Curly-leaved Pondweed, Eurasian Milfoil and Najas minor.

There are many alternate names for these invasive plants! Below is a list of Maine's illegal aquatic plants organized by scientific name, common name and known pseudonyms. Verify the scientific name when purchasing aquatic plants.
