Add a plant
Snap a photo or type the name. The app pulls 4,000+ species from peer-reviewed horticulture data and starts a care plan tailored to your zone, the local weather, and the time of year.
43 states publish a list of the plants they regulate. All 43 are reproduced here in full, 2,130 listings, each one citing the statute or administrative code it comes from.
A listing tells you what a state regulates, not where a plant belongs. Nativity is a county-level question, so use the county checker for a specific address.
Looking for one plant rather than one state?
Check a plant against your county →These 7 have no page, rather than a page reporting zero. Some publish no state-wide list at all; for others Ezina has not sourced one yet. Either way, saying nothing is regulated there would be wrong, so we do not say it.
The county checker still works in all of them, because nativity comes from USDA records rather than from state law. If you know of a published list we are missing, send it to [email protected].
43 states have a published invasive-plant or noxious-weed list that Ezina reproduces: Alabama, Arizona, Arkansas, California, Colorado, Connecticut, Delaware, Florida, Idaho, Illinois, Indiana, Iowa, Kansas, Louisiana, Maine, Maryland, Massachusetts, Michigan, Minnesota, Mississippi, Missouri, Montana, Nebraska, Nevada, New Hampshire, New Jersey, New Mexico, New York, North Carolina, North Dakota, Ohio, Oklahoma, Oregon, Pennsylvania, South Carolina, South Dakota, Tennessee, Utah, Vermont, Virginia, Washington, West Virginia, Wisconsin. The remaining states either publish no list or publish one Ezina has not yet sourced.
Washington regulates the most, at 166 species, followed by California (162) and Massachusetts (144). Oklahoma regulates the fewest, at 3.
Usually, but a list is a legal instrument rather than an ecological verdict. Plants spread aggressively long before a state gets around to naming them, and states add species years after the problem is documented. Absence from a list is not a recommendation.
