Your yard isn't the whole zone.
Tepary Bean is grown as an annual, so your winter zone isn't the deciding factor — your frost-free window is. A typical Alabama site runs ~266 frost-free days, but that is a state median, not your yard: slope, trees, and low spots move the last-frost date across a single parcel. Enter your address and we'll score tepary bean against your land's actual frost dates, sun, and soil.

Alabama is not one climate
A single Alabama answer averages 67 counties whose growing seasons are 72 days apart — from 225 frost-free days in Marion County to 297 in Mobile County. Which end of that your land sits nearer changes what tepary bean can finish before the first hard freeze.
The middle half of 67 counties runs 244–277 days, with a median of 266 days — a 72-day span end to end.

When to Plant Tepary Bean in Alabama
The frost window
Across Alabama, the last spring hard freeze (28°F) clears between Feb 24 and Mar 16, and the first fall hard freeze lands between Nov 15 and Nov 28 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 244-day window you can count on — up to 277 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.
Frost hardiness
Tepary Bean takes cold down to about 28°F before a freeze kills it, so you can plant on the early side of Alabama's window — even a few weeks before the final hard freeze. That is the point where cold damages growing tissue, not a winter-survival floor — an established perennial comes through far colder while dormant, which is what its hardiness zone tells you. We haven't confirmed this against a published source yet.
When to start the seed
Tepary Bean is direct-sown where it grows rather than started under cover, so there is no seed-tray head start to bank — Alabama's dates above are the whole calendar for it. That makes the last-freeze date the binding constraint, and a warmer pocket of your own yard is worth more to this crop than it is to a transplanted one.
Days to maturity vs. the window
At 90 days to maturity (Growable Ground Plant Database), counting from the last hard freeze it ripens with 154 days to spare even in Alabama's tightest freeze scenario — room for a later start or a second sowing.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. Your site's own frost dates can run earlier or later than the state range — a parcel report pins them down.
Growing Season Fit
Tepary Bean is grown in zones 5–11, which covers every zone Alabama contains (7b-9b). It is grown as a summer crop, so season length decides it here. Alabama's typical season runs ~266 frost-free days against the ~60 tepary bean needs.
Frost-free days
Tepary Bean wants 60+ frost-free days; a typical Alabama site sees ~266 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Tepary Bean needs ~1800 GDD (base 50°F) to ripen. We haven't confirmed this against a published source yet. The state median runs ~5383 GDD (from PRISM 1991-2020 climate normals), so Alabama's typical season clears that easily.
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
Tepary Bean tolerates a wide pH range (pH 5-8) — 3 units, acid ground through alkaline — so soil acidity is rarely what limits it in Alabama. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 6 and 7 — worth knowing before you decide whether a Alabama soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Alabama site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost.

Before you plant tepary bean for food
Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before tepary bean goes in. What follows is Alabama’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.
Safe to Grow Here?
What the federal record shows across Alabama — and how to grow with it.
We checked the federal record across Alabama — 20,346 documented sites across 7 of the 8 source types we track.
The most significant on record: 327 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Alabama carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds of imported, lab-tested soil grow well almost anywhere in the meantime.

What Else to Consider for Tepary Bean in Alabama
The zone range tells you where tepary bean is grown — but Alabama growers also need to think about:
Heavy clay soils in the Piedmont region
High humidity promotes fungal diseases
Fire ants are a persistent garden pest
What to actually do about these — and the constraints that apply to every Alabama grower, not just tepary bean — is covered on the Alabama growing guide.
Timing shifts within Alabama
Tepary Bean needs about 60 days of frost-free season to complete its cycle. Even Marion County — Alabama’s shortest season at 225 frost-free days — clears that by 165 days, so season length isn’t the constraint anywhere in Alabama. What varies is your own parcel.
Across Alabama’s 67 counties the frost-free season runs from 225 days in Marion County to 297 days in Mobile County — a spread of 72 days, which is why a single statewide planting date misleads. The median Alabama county sees 266 frost-free days, leaving tepary bean about 206 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"). Tepary Bean's 60-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Tepary Bean draws honeybees and native bees (moderate value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, tepary bean can only work that bloom inside Alabama's frost window — roughly 266 days, opening after the last 28°F freeze (Feb 24 - Mar 16) and closing at the first (Nov 15 - Nov 28), per NOAA Regional Climate Centers ACIS, 1991-2020. Pollinator value: We haven't confirmed this against a published source yet.

Common Questions About Growing Tepary Bean in Alabama
When can I plant Tepary Bean in Alabama?
Alabama's last spring hard freeze (28°F) clears between Feb 24 and Mar 16, and the first fall hard freeze lands between Nov 15 and Nov 28 (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 Tepary Bean mature before first frost in Alabama?
Yes — Tepary Bean matures in 90 days (Growable Ground Plant Database), and Alabama's dependable hard-freeze-free window runs 244 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 154 days of margin. Plant once the last hard freeze has passed — two to three weeks later for anything tender — and it ripens ahead of the first fall freeze.
What hardiness zone is Tepary Bean grown in across Alabama?
Alabama spans USDA hardiness zones 7b-9b (USDA ARS PHZM 2023). Tepary Bean carries a range of zones 5-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Alabama site have?
A typical Alabama site sees ~266 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Tepary Bean needs 60+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Tepary Bean native to Alabama?
Tepary Bean is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-10-19) does not record it growing in Alabama. It can still earn a place in a Alabama garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Tepary Bean in Alabama?
Tepary Bean tolerates pH 5-8 and well (dry spells) drainage (FAO ECOCROP). That is a 3-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Alabama site — amend for drainage and organic matter first.
Will Tepary Bean actually grow on my specific land in Alabama?
