Arkansas noxious weeds
Arkansas (AR) lists 27 plants as noxious weeds under 2 CAR 50-101(d) (Circular 11). Arkansas's list is an agricultural noxious-weed law, which governs control and spread on farmland and rights of way rather than what a nursery may sell.
What plants are invasive in Arkansas?
Arkansas names 27 plants, including Purple Loosestrife, Field Bindweed and Johnsongrass. A noxious-weed listing obliges control and limits movement; it does not by itself ban nursery sale. 19 of the 27 are also flagged invasive by GRIIS, which is an ecological finding rather than a ruling by Arkansas. Checked against 2 CAR 50-101(d) (Circular 11) on July 20, 2026.

No plant on Arkansas’s list matches that.
6 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 Arkansas regulates, not where a plant belongs. The county checker answers the second question.

Where this comes from
- Arkansas listings
- 2 CAR 50-101(d) (Circular 11). 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 Arkansas’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 Arkansas
Plants that two or more states bordering Arkansas regulate, and Arkansas 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.

- Jio Commelina benghalensis regulated in Mississippi, Tennessee
- Kariba-Weed Salvinia molesta regulated in Mississippi, Tennessee

Questions
Is there an official Arkansas invasive species list?
Not under that name. Arkansas's legal list is a noxious-weed list: 27 plants named under 2 CAR 50-101(d) (Circular 11), an agricultural noxious-weed law, which governs control and spread on farmland and rights of way rather than what a nursery may sell. GRIIS, the Global Register of Introduced and Invasive Species, flags 19 of these 27 as invasive in the lower 48 states. That is an ecological finding, not a ruling by Arkansas. This page shows both side by side.
What plants are illegal to sell in Arkansas?
Arkansas's list is an agricultural noxious-weed law, which governs control and spread on farmland and rights of way rather than what a nursery may sell. 27 plants are named under 2 CAR 50-101(d) (Circular 11). A noxious-weed listing does not automatically ban nursery sale, so check the rule itself before assuming a plant cannot be bought or sold.
Is my plant invasive in Arkansas?
Search the table on this page for Arkansas's legal determination, then look for the Invasive chip beside it, which is a separate ecological finding from GRIIS rather than a ruling by Arkansas. 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 Arkansas 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 Arkansas?
Not necessarily, and the distinction matters. Arkansas's list is an agricultural noxious-weed law: it obliges landowners to control these plants and restricts moving them, rather than making the act of planting one an offence in itself. 2 CAR 50-101(d) (Circular 11) is the text that says what is actually required of you, and it is linked beside every plant here.
Does a plant missing from this list mean it is safe to plant in Arkansas?
No. This page reproduces what Arkansas 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.
