Invasive plants regulated in New York
New York regulates 65 invasive plants under 6 NYCRR 575.3 (prohibited) / 575.4 (regulated). The table below reproduces that list in full, showing each plant's status in the state's own words. New York's list is a trade restriction, which governs what may be sold, propagated, or moved within the state.
Compiled from the rule itself, retrieved July 20, 2026. Law changes; if you spot a listing we have wrong or stale, tell us at [email protected].
Want the answer for one plant, at your address?
Check a plant against your county →4 of these plants are native to part of the United States, marked US native below. Nativity is regional. Black locust is native to the Appalachians and regulated in New England; Palmer amaranth is native to the Southwest and listed as an agricultural weed in the Corn Belt. A listing tells you what New York regulates, not where a plant belongs. The county checker answers the second question.
Regulated and invasive are two different findings, and this page shows them separately. 53 of the 65 plants below carry both: New York names them in statute and GRIIS lists them as invasive in the United States. The other 12 are regulated by New York without appearing on that register. The reverse is far more common still: most plants GRIIS calls invasive are named in no state’s statute at all and are sold freely, so an absent chip is never a clean bill of health.

Where this comes from
- New York listings
- 6 NYCRR 575.3 (prohibited) / 575.4 (regulated). Read the rule.
- Invasive status
- GRIIS, the Global Register of Introduced and Invasive Species, via GBIF. A scientific register with no legal force; it is cited separately from the statute above because the two disagree far more often than they agree.
- Status wording
- Each determination is written as a sentence, with New York’s own term for the plant reproduced verbatim inside it. The Prohibited / Restricted / Listed chips are Ezina’s normalisation across 42 states and are not the legal term.
- Nativity
- USDA PLANTS county distribution layer, surfaced through the county checker.
Regulated next door, but not in New York
Plants that two or more states bordering New York regulate, and New York does not. A listing is a legal act rather than an ecological one, so a plant can be a documented problem here and still be sold here.

Questions
What plants are illegal to sell in New York?
65 plants are regulated under 6 NYCRR 575.3 (prohibited) / 575.4 (regulated). Plants marked Prohibited may not be sold, propagated, or moved within New York. Plants marked Restricted carry narrower limits set by the rule.
Is my plant invasive in New York?
Search the table on this page, or enter the plant's name in Ezina's checker to get its New York status alongside whether USDA records it as native to your specific county. Every answer links the record it came from.
Does a plant missing from this list mean it is safe to plant in New York?
No. This page reproduces what New York regulates, and a state list is a legal instrument rather than an ecological verdict. Plenty of plants spread aggressively without ever being listed, and states add species years after the problem is documented.
