Midwest Invasive Plant List

Over 300 plant species are considered to be invasive, noxious, or pests by one or more jurisdictions in the Midwestern U.S. The following regional list compiles all the plant species regulated through state law and/or listed as invasive by a state agency or invasive plant council in the eight-state region that MIPN serves. Click here to learn more about the risk assessment processes that are used to determine invasiveness.

The list is presented alphabetically by Latin name but is easily searchable by common or Latin name – just start typing in the search box! You can also sort the database by listing status by clicking the carrot next to each column header.

Links to the appropriate state laws or agency/plant council webpages are provided in the index below. If you are aware of an updated list or amended law, please help us keep this list up to date by emailing MIPN’s Coordinator at mipn@mortonarb.org.
