Invasive plants regulated in New Jersey
New Jersey regulates 29 invasive plants under N.J. Invasive Species Management Act, P.L.2025 c.290, sec. 4.a. The table below reproduces that list in full, showing each plant's status in the state's own words. New Jersey'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 →29 of these listings are phasing in. The species is named in the rule, but the sale ban has not taken effect yet, so New Jersey nurseries may still legally sell it today. The dates are shown in the table.
Regulated and invasive are two different findings, and this page shows them separately. 26 of the 29 plants below carry both: New Jersey names them in statute and GRIIS lists them as invasive in the United States. The other 3 are regulated by New Jersey 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 Jersey listings
- N.J. Invasive Species Management Act, P.L.2025 c.290, sec. 4.a. 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 Jersey’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 Jersey
Plants that two or more states bordering New Jersey regulate, and New Jersey 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 Jersey?
29 plants are regulated under N.J. Invasive Species Management Act, P.L.2025 c.290, sec. 4.a. Plants marked Prohibited may not be sold, propagated, or moved within New Jersey. Plants marked Restricted carry narrower limits set by the rule.
Is my plant invasive in New Jersey?
Search the table on this page, or enter the plant's name in Ezina's checker to get its New Jersey 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 Jersey?
No. This page reproduces what New Jersey 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.
