Federal Noxious Weed List

In accordance with the Plant Protection Act of 2000 (7 U.S.C. 7701 et seq.), the U.S. government has designated certain plants as noxious weeds:

Federal and State Noxious Weeds

This composite list is a summary of noxious status for all of the listed plants in the U.S.

Weeds of the U.S.

These plants are weedy or invasive, or have the potential to become weedy or invasive, in all or part of their U.S. range. We assembled this list verbatim from sources around the country to provide a comprehensive look at potential problem plants in the U.S. Most are introduced to the United States, but some are harmful pests in parts of this country, and valuable natives in others. To learn more, please read About Weeds of the U.S.

You may view individual weed lists assembled by state and federal resource managers, state Exotic Plant Pest Councils, or university noxious weed specialists, or a composite list that is derived from these individual lists.

Introduced Plants of the PLANTS Floristic Area

These plants are introduced to some part of the PLANTS Floristic Area, though they may be native in other parts. While many are harmless or beneficial, others that are not already invasive or noxious have a high potential to become so in all or part of their range. In general, introduced plants are likely to invade or become noxious since they lack co-evolved competitors and natural enemies to control their populations.
