New York invasive plants

New York (NY) regulates 65 invasive plants under 6 NYCRR 575.3 (prohibited) / 575.4 (regulated). New York's list is a trade restriction, which governs what may be sold, propagated, or moved within the state — in plain terms, which plants are illegal to sell here.

New York invasive species list

New York restricts 65 plants, including Purple Loosestrife, Leafy Spurge and Waterthyme. Plants marked Prohibited may not be sold, propagated, or moved within New York. 53 of the 65 are also flagged invasive by GRIIS, which is an ecological finding rather than a ruling by New York. Checked against 6 NYCRR 575.3 (prohibited) / 575.4 (regulated) on July 20, 2026.

4 of these plants are native to part of the United States, marked US native above. 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.

What the tags mean

Two separate findings. Invasive is ecological. The other three are legal statuses New York sets in statute, and which one applies turns on what the rule obliges, and of whom.

Invasive
An ecological finding, and a different question from the law. GRIIS — the Global Register of Introduced and Invasive Species — lists the plant as invasive in the lower 48 states. Most invasive plants carry no state listing at all and are sold freely, so a plant without this tag is not thereby safe, and a plant without a legal chip is not thereby harmless.
Prohibited
May not be sold, moved, propagated or possessed at all.
Restricted
May still be sold or held, but under conditions — retail signage, an identification tag, or a carve-out for sterile cultivars.
Listed
Designated, but the duty to control it falls on landowners rather than on the nursery trade.

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, covering the lower 48 states. 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. Garden crops it flags only for spreading from cultivation are left out after review.
Status wording
The Prohibited / Restricted / Listed chips are Ezina’s normalisation across 44 states and are not the legal term. Where New York’s own word for a plant differs from the chip, it is quoted verbatim beneath it.
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

Is there an official New York invasive species list?

Yes. 6 NYCRR 575.3 (prohibited) / 575.4 (regulated) is New York's list, naming 65 plants under a trade restriction, which governs what may be sold, propagated, or moved within the state — in plain terms, which plants are illegal to sell here. GRIIS, the Global Register of Introduced and Invasive Species, flags 53 of these 65 as invasive in the lower 48 states. That is an ecological finding, not a ruling by New York. This page shows both side by side.

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 for New York's legal determination, then look for the Invasive chip beside it, which is a separate ecological finding from GRIIS rather than a ruling by New York. A plant can carry one, both, or neither. For an address-level answer, 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.

Is it illegal to plant these in New York?

For the plants marked Prohibited, 6 NYCRR 575.3 (prohibited) / 575.4 (regulated) bars selling, propagating, or moving them within New York. Whether planting one you already own is itself an offence depends on that rule's exact wording, which is why every plant on this page links the citation rather than us paraphrasing it. Plants marked Restricted carry narrower limits the rule sets out.

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.

Grow natives easily with Ezina

How it works

We provide the tools you need to succeed.

The Ezina app identifying a plant: a live camera view framing pink coneflowers, with Plant, Disease/Insect, and Both scan modes.
010.1Identify

Add a plant

Snap a photo or type the name. Ezina matches it to a library of about 40,000 species and starts a care plan tailored to your zone, the local weather, and the time of year.

The Ezina app’s care screen: water needs showing status Okay, last watered 12 days ago, a suggested volume, and a treatment section.
010.2Care

Get a care plan

A schedule built from local rain, temperature, and sun, not a fixed weekly cadence. You get a single notification when a plant actually needs water. Easily add treatments for diseases and pests.

The Ezina Dig planner: a starting-plan site map with suggested garden beds you can draw with your finger.
010.3Plan
