What plants are illegal to sell in Ohio?

86 plants are regulated under Ohio Admin. Code 901:5-37-01 (noxious weeds) + 901:5-30-01 (invasive plants). Plants marked Prohibited may not be sold, propagated, or moved within Ohio. Plants marked Restricted carry narrower limits set by the rule.

Is my plant invasive in Ohio?

Search the table on this page for Ohio's legal determination, then look for the Invasive chip beside it, which is a separate ecological finding from GRIIS rather than a ruling by Ohio. 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 Ohio 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 Ohio?

For the plants marked Prohibited, Ohio Admin. Code 901:5-37-01 (noxious weeds) + 901:5-30-01 (invasive plants) bars selling, propagating, or moving them within Ohio. 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 Ohio?

No. This page reproduces what Ohio 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.

Ohio invasive plants: all 86, with the law cited

Q: Is there an official Ohio invasive species list?

Yes. Ohio Admin. Code 901:5-37-01 (noxious weeds) + 901:5-30-01 (invasive plants) is Ohio's list, naming 86 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 65 of these 86 as invasive in the lower 48 states. That is an ecological finding, not a ruling by Ohio. This page shows both side by side.
