Maine invasive plants

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 Maine regulates, not where a plant belongs. The county checker answers the second question.

Where this comes from
- Maine listings
- 01-001 CMR Ch. 273. 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 Maine’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.
Questions
Is there an official Maine invasive species list?
Yes. 01-001 CMR Ch. 273 is Maine's list, naming 64 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 49 of these 64 as invasive in the lower 48 states. That is an ecological finding, not a ruling by Maine. This page shows both side by side.
What plants are illegal to sell in Maine?
64 plants are regulated under 01-001 CMR Ch. 273. Plants marked Prohibited may not be sold, propagated, or moved within Maine. Plants marked Restricted carry narrower limits set by the rule.
Is my plant invasive in Maine?
Search the table on this page for Maine's legal determination, then look for the Invasive chip beside it, which is a separate ecological finding from GRIIS rather than a ruling by Maine. 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 Maine 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 Maine?
For the plants marked Prohibited, 01-001 CMR Ch. 273 bars selling, propagating, or moving them within Maine. 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 Maine?
No. This page reproduces what Maine 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.
