Conditional — Some Areas
plantain (zones 9-11) reaches only part of New Mexico (5a-9a): zone 9 are in range, so where you are in the state decides it.
Your yard isn't the whole zone.
New Mexico spans zones 5a-9a, but your yard has its own microclimate — slope, trees, and low spots shift frost and sun across a single parcel. Enter your address and we'll score plantain against your land's actual soil, sun, and frost.

When to Plant Plantain in New Mexico
The frost window
Across New Mexico, the last spring hard freeze (28°F) clears between Mar 31 and Apr 19, and the first fall hard freeze lands between Oct 22 and Nov 9 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 186-day window you can count on — up to 223 days on a mild site in a kind year. That marks the hard freeze, not the last light frost, so tender transplants usually wait another 2-3 weeks.
Days to maturity vs. the window
At 300 days to maturity (USDA PLANTS Database), even New Mexico's kindest 223-day season runs short — challenging without season extension. An indoor start plus row cover on both shoulders of the season closes the gap.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: USDA PLANTS Database. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
The zone check says plantain survives winter in part of New Mexico, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Days to maturity
Plantain matures in ~300 days (Growable Ground Plant Database). A typical New Mexico site has ~209 frost-free days, so tight — start indoors or use season-extension to close the gap.
Growing degree days
Plantain needs ~5000 GDD (base 50°F) to ripen. The state median runs ~2899 GDD (from PRISM 1991-2020 climate normals), so New Mexico's typical season runs short on heat — pick a south-facing site and consider season extension.
GDD and chill-hour figures are computed from PRISM 1991-2020 monthly climate normals; frost-free days from NOAA Regional Climate Centers ACIS, 1991-2020. Each is the state median across its counties (P25/P75 span the within-state spread). Hardiness-zone range is USDA PHZM 2023.

What Else to Consider for Plantain in New Mexico
Zone compatibility tells you about winter cold survival — but New Mexico growers also need to think about:
Very low rainfall requires irrigation for most crops
High altitude UV intensity can burn tender transplants
Alkaline soils limit plant selection without amendment
What to actually do about these — and the constraints that apply to every New Mexico grower, not just plantain — is covered on the New Mexico growing guide.
Timing shifts within New Mexico
Plantain needs about 300 days of frost-free season from planting to harvest. No New Mexico county gives it that outdoors: even Doña Ana County, the state’s longest season at 264 frost-free days, falls 36 days short — so it needs transplants, a short-season variety, or covered growing.
Across New Mexico’s 33 counties the frost-free season runs from 144 days in Catron County to 264 days in Doña Ana County — a spread of 120 days, which is why a single statewide planting date misleads. The median New Mexico county sees 209 frost-free days, which is 91 days short of what plantain needs — so on a typical New Mexico parcel this is a transplant-or-protect crop, not a direct-sow one.
County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). Plantain's 300-day requirement: USDA PLANTS / Growable Ground plant database (days to maturity). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Plantain draws hummingbirds (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, plantain can only work that bloom inside New Mexico's frost window — roughly 209 days, opening after the last 28°F freeze (Mar 31 - Apr 19) and closing at the first (Oct 22 - Nov 9), per NOAA Regional Climate Centers ACIS, 1991-2020.

Common Questions About Growing Plantain in New Mexico
When can I plant Plantain in New Mexico?
New Mexico's last spring hard freeze (28°F) clears between Mar 31 and Apr 19, and the first fall hard freeze lands between Oct 22 and Nov 9 (NOAA Regional Climate Centers ACIS, 1991-2020). Time outdoor planting to after the last hard freeze for your specific site — a further two to three weeks for anything tender — and count back from those dates for transplant scheduling.
Can Plantain mature before first frost in New Mexico?
Plantain needs 300 days to mature (USDA PLANTS Database), and even New Mexico's longest typical season runs 223 days (NOAA Regional Climate Centers ACIS, 1991-2020) — challenging without season extension. An indoor start plus row cover on both season shoulders closes the gap.
What hardiness zone is Plantain grown in across New Mexico?
New Mexico spans USDA hardiness zones 5a-9a (USDA ARS PHZM 2023). Plantain carries a range of zones 9-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical New Mexico site have?
A typical New Mexico site sees ~209 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Plantain should be matched against that window, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Will Plantain actually grow on my specific land in New Mexico?
