Unlikely — Zone Mismatch
lime-yellow pea (zones 10-13) does not overlap with Alabama's zone range (7b-9b). Growing outdoors is unlikely without significant protection.
One zone short — what would close it
Lime Yellow Pea is hardy to zone 10, and the warmest ground in Alabama is zone 9 — 1 zone short. Planted in open ground it will not survive a Alabama winter. To grow it here, grow lime yellow pea in a container and move it under cover for the coldest weeks, or give it a greenhouse.
Season extension and overwintering under cover both work at this margin. How to buy the weeks →

When to Plant Lime Yellow Pea 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.
Winter standing
Alabama runs as cold as USDA zone 7, and no sourced winter-hardiness floor is on record for lime yellow pea, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether lime yellow pea is a permanent planting or a replant-every-spring crop for you turns on your own zone within Alabama; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Marion County, not the statewide average.
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 lime yellow pea does not survive a Alabama winter in the ground. The season figures below measure a different question — whether it could finish a season here at all — and they only bear on Alabama under protection.
Frost-free days
Lime Yellow Pea wants 140+ 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
Lime Yellow Pea likes near-neutral soil (pH 5.5-7.5). That's the common-ground band across Alabama's red clay and sandy loam — 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 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, raised beds or amendment with compost solve it.
Your land, not the state average
SSURGO maps about 14.1% of Alabama as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Lime Yellow Pea tolerates drought well, so wet feet — not dry spells — is its real risk here — your soil map unit, not the state average, is the real answer.

- Plant Zones: 10-13 (USDA PLANTS Database)
- State Zones: 7b-9b (USDA ARS PHZM 2023)

What Else to Consider for Lime Yellow Pea 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
Growing lime yellow pea here specifically
Lime Yellow Pea roots run medium and prefer pH 5.5–7.5, but drainage comes first here: SSURGO maps about 14.1% of Alabama as poorly or somewhat-poorly drained, and wet ground rots its crown before pH ever matters.
Plant lime yellow pea on a raised, gravel-amended berm so water drains fast and the crown stays dry. How to handle it →
What to actually do about these — and the constraints that apply to every Alabama grower, not just lime yellow pea — is covered on the Alabama growing guide.
Timing shifts within Alabama
Alabama isn't one climate. In Marion County, the last hard freeze (28°F) holds until about Mar 28 — roughly 26 days later than the recorded state median — so plant lime yellow pea to your county's window, not the statewide date.
Lime Yellow Pea needs about 140 days of frost-free season to complete its cycle. Even Marion County — Alabama’s shortest season at 225 frost-free days — clears that by 85 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 lime yellow pea about 126 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"). Lime Yellow Pea's 140-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
Lime Yellow Pea draws honeybees (low value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, lime yellow pea 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.
Alabama Cooperative Extension
For Alabama-specific cultivar recommendations, planting calendars, and pest pressure for lime yellow pea, the canonical source is Alabama Cooperative Extension System. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Lime Yellow Pea native to Alabama?
No — the USDA PLANTS Database lists Lime Yellow Pea as introduced rather than native in the Lower 48, so it is not part of Alabama's native flora. It grows here as a garden plant; pairing it with a few Alabama natives keeps local pollinators fed too.

Common Questions About Growing Lime Yellow Pea in Alabama
When can I plant Lime Yellow Pea 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). No sourced winter-hardiness floor is on record for Lime Yellow Pea, so this page does not state whether it overwinters in Alabama 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 Lime Yellow Pea grown in across Alabama?
Alabama spans USDA hardiness zones 7b-9b (USDA ARS PHZM 2023). Lime Yellow Pea carries a range of zones 10-13, 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). Lime Yellow Pea needs 140+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Marion, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Lime Yellow Pea native to Alabama?
No — the USDA PLANTS Database lists Lime Yellow Pea as introduced rather than native in the Lower 48, so it is not part of Alabama's native flora. It grows here as a garden plant; pairing it with a few Alabama natives keeps local pollinators fed too.
How should I amend the soil for Lime Yellow Pea in Alabama?
Lime Yellow Pea prefers pH 5.5-7.5 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Alabama soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Lime Yellow Pea actually grow on my specific land in Alabama?
