Federal Noxious Weed List
In accordance with the Federal
Noxious Weed Act of 1974, as amended (7 U.S.C. 2801 et seq.), the U.S.
government has designated certain plants as noxious weeds:

The following states have designated certain plants as legally noxious:
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.
