Generally — Most Areas
pyracantha (zones 6-9) suits most of New Mexico (5a-9a) — zones 6-9 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
New Mexico spans zones 5a-9a, but your yard sits in exactly one — and slope, tree cover, and cold-air pockets nudge it further. Enter your address and we'll score pyracantha against your parcel's actual hardiness, soil, and sun.

When to Plant Pyracantha 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.
Winter standing
New Mexico runs as cold as USDA zone 5, and no sourced winter-hardiness floor is on record for pyracantha, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether pyracantha is a permanent planting or a replant-every-spring crop for you turns on your own zone within New Mexico; check its hardiness range against that before treating it as long-lived ground.
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 pyracantha 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.
Frost-free days
Pyracantha wants 150+ frost-free days; a typical New Mexico site sees ~209 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a workable window — start indoors to bank time.
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.
Soil + Drainage Fit
Pyracantha likes near-neutral soil (pH 5.5-7.5). That's the common-ground band across New Mexico's sandy loam and caliche — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6 and 7 — worth knowing before you decide whether a New Mexico soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your New Mexico site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Pyracantha 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 pyracantha — is covered on the New Mexico growing guide.
Timing shifts within New Mexico
Pyracantha needs about 150 days of frost-free season to complete its cycle. 32 of New Mexico’s 33 counties give it that outright. The tightest that does is Cibola County at 150 frost-free days — 0 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
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, leaving pyracantha about 59 days of slack on a typical parcel — room for a second sowing where the season runs long.
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"). Pyracantha's 150-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in New Mexico Fits Best
Even within New Mexico's zones 5a-9a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for pyracantha (USDA PHZM 2023):
Pollinator + Wildlife Value
Pyracantha draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, pyracantha 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.
New Mexico Cooperative Extension
For New Mexico-specific cultivar recommendations, planting calendars, and pest pressure for pyracantha, the canonical source is NMSU Cooperative Extension Service. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Pyracantha native to New Mexico?
No — the USDA PLANTS Database lists Pyracantha as introduced rather than native in the Lower 48, so it is not part of New Mexico's native flora. It grows here as a garden plant; pairing it with a few New Mexico natives keeps local pollinators fed too.

Common Questions About Growing Pyracantha in New Mexico
When can I plant Pyracantha 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). No sourced winter-hardiness floor is on record for Pyracantha, so this page does not state whether it overwinters in New Mexico and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is Pyracantha grown in across New Mexico?
New Mexico spans USDA hardiness zones 5a-9a (USDA ARS PHZM 2023). Pyracantha carries a range of zones 6-9, 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). Pyracantha needs 150+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Pyracantha native to New Mexico?
No — the USDA PLANTS Database lists Pyracantha as introduced rather than native in the Lower 48, so it is not part of New Mexico's native flora. It grows here as a garden plant; pairing it with a few New Mexico natives keeps local pollinators fed too.
How should I amend the soil for Pyracantha in New Mexico?
Pyracantha prefers pH 5.5-7.5 and well (dry spells) drainage (Growable Ground Plant Database). That sits in the common-ground band across New Mexico soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
