New Mexico noxious weeds
New Mexico (NM) lists 36 plants as noxious weeds under New Mexico Noxious Weed List (June 2020 memo), NMSA 1978 76-7D-1 et seq.. New Mexico'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 New Mexico?
New Mexico names 36 plants, including Purple Loosestrife, Canada Thistle and Leafy Spurge. A noxious-weed listing obliges control and limits movement; it does not by itself ban nursery sale. 34 of the 36 are also flagged invasive by GRIIS, which is an ecological finding rather than a ruling by New Mexico. Checked against New Mexico Noxious Weed List (June 2020 memo), NMSA 1978 76-7D-1 et seq. on July 20, 2026.

Where this comes from
- New Mexico listings
- New Mexico Noxious Weed List (June 2020 memo), NMSA 1978 76-7D-1 et seq.. 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 Mexico’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 Mexico
Plants that two or more states bordering New Mexico regulate, and New Mexico 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 Mexico invasive species list?
Not under that name. New Mexico's legal list is a noxious-weed list: 36 plants named under New Mexico Noxious Weed List (June 2020 memo), NMSA 1978 76-7D-1 et seq., 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 34 of these 36 as invasive in the lower 48 states. That is an ecological finding, not a ruling by New Mexico. This page shows both side by side.
What plants are illegal to sell in New Mexico?
New Mexico'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. 36 plants are named under New Mexico Noxious Weed List (June 2020 memo), NMSA 1978 76-7D-1 et seq.. 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 New Mexico?
Search the table on this page for New Mexico'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 Mexico. 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 Mexico 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 Mexico?
Not necessarily, and the distinction matters. New Mexico'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. New Mexico Noxious Weed List (June 2020 memo), NMSA 1978 76-7D-1 et seq. 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 New Mexico?
No. This page reproduces what New Mexico 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.
