Amur Corktree – Phellodendron amurense IntroducedInvasive
Invasive in the US, and recorded in 8 of New York’s 62 counties. New York lists Amur Corktree under “prohibited.”
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 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.

Where this comes from
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.
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.
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.
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.
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.
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.
