Your yard isn't the whole zone.
Alabama spans zones 7b-9b, 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 african foxtail against your land's actual soil, sun, and frost.

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 african foxtail 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.

Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where in Alabama Fits Best
African Foxtail is rated for zones 8–13 — a cold floor USDA puts at 10 to 20°F. Against Alabama’s 67 counties that band holds in 63 of them, and the line runs at Bibb County (zone 8a), the coldest county still inside it.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. A zone is a 10°F band of average annual extreme minimum temperature, so the floor above is the band the plant's rating denotes, not a single measured kill point. Slope, shelter and cold-air drainage routinely move a site half a zone either way from its county figure — which is the part only your address resolves.
Even within Alabama's zones 7b-9b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for african foxtail (USDA PHZM 2023):

When to Plant African Foxtail 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.
When to start the seed
African Foxtail 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.
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
The zone check says african foxtail survives winter in part of Alabama, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
African Foxtail wants 120+ frost-free days; a typical Alabama site sees ~266 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
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
African Foxtail tolerates a wide pH range (pH 5.5-8.5) — 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 6.5 and 8 — 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), excessive (dry/moderately dry). If your Alabama site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for African Foxtail in Alabama
Zone compatibility tells you about winter cold survival — 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 african foxtail — is covered on the Alabama growing guide.
Timing shifts within Alabama
African Foxtail needs about 120 days of frost-free season to complete its cycle. Even Marion County — Alabama’s shortest season at 225 frost-free days — clears that by 105 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 african foxtail about 146 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"). African Foxtail's 120-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.

Common Questions About Growing African Foxtail in Alabama
When can I plant African Foxtail 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.
What hardiness zone is African Foxtail grown in across Alabama?
Alabama spans USDA hardiness zones 7b-9b (USDA ARS PHZM 2023). African Foxtail carries a range of zones 8-13, 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). African Foxtail needs 120+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
How should I amend the soil for African Foxtail in Alabama?
African Foxtail tolerates pH 5.5-8.5 and well (dry spells), excessive (dry/moderately dry) 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 African Foxtail actually grow on my specific land in Alabama?
