Your yard isn't the whole zone.
Black-Eyed Pea is grown as an annual, so your winter zone isn't the deciding factor — your frost-free window is. A typical Nebraska site runs ~181 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 black-eyed pea against your land's actual frost dates, sun, and soil.

Nebraska is not one climate
A single Nebraska answer averages 93 counties whose growing seasons are 73 days apart — from 134 frost-free days in Sioux County to 207 in Sarpy County. Which end of that your land sits nearer changes what black-eyed pea can finish before the first hard freeze.
The middle half of 93 counties runs 173–191 days, with a median of 181 days — a 73-day span end to end.

When to Plant Black-Eyed Pea in Nebraska
The frost window
Across Nebraska, the last spring hard freeze (28°F) clears between Apr 12 and Apr 26, and the first fall hard freeze lands between Oct 15 and Oct 21 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 172-day window you can count on — up to 192 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
Black-Eyed Pea is direct-sown where it grows rather than started under cover, so there is no seed-tray head start to bank — Nebraska'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 70 days to maturity (Growable Ground Plant Database), counting from the last hard freeze it ripens with 102 days to spare even in Nebraska'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
The zone check says black-eyed pea survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Black-Eyed Pea wants 30+ frost-free days; a typical Nebraska site sees ~181 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Black-Eyed Pea needs ~2000 GDD (base 50°F) to ripen. The state median runs ~2648 GDD (from PRISM 1991-2020 climate normals), so Nebraska'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
Black-Eyed Pea tolerates a wide pH range (pH 4-8.8) — 4.8 units, acid ground through alkaline — so soil acidity is rarely what limits it in Nebraska. 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 5.5 and 7.5 — worth knowing before you decide whether a Nebraska soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Nebraska site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

Before you plant black-eyed pea 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 black-eyed pea goes in. What follows is Nebraska’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 Nebraska — and how to grow with it.
We checked the federal record across Nebraska — 10,663 documented sites across 8 of the 9 source types we track.
The most significant on record: 162 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Nebraska 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 with clean imported soil grow well almost anywhere in the meantime.

What an experienced grower watches for around here
In and around Nebraska, two things run higher than the national average across Nebraska — CAFO (700 sites) and Nitrate (4,328 sites). It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.
What Else to Consider for Black-Eyed Pea in Nebraska
Zone compatibility tells you about winter cold survival — but Nebraska growers also need to think about:
Low western rainfall (15 inches) requires irrigation
Extreme wind exposure on open plains
Hail damage during severe storm season
What to actually do about these — and the constraints that apply to every Nebraska grower, not just black-eyed pea — is covered on the Nebraska growing guide.
Timing shifts within Nebraska
Black-Eyed Pea needs about 30 days of frost-free season to complete its cycle. Even Sioux County — Nebraska’s shortest season at 134 frost-free days — clears that by 104 days, so season length isn’t the constraint anywhere in Nebraska. What varies is your own parcel.
Across Nebraska’s 93 counties the frost-free season runs from 134 days in Sioux County to 207 days in Sarpy County — a spread of 73 days, which is why a single statewide planting date misleads. The median Nebraska county sees 181 frost-free days, leaving black-eyed pea about 151 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"). Black-Eyed Pea's 30-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
Black-Eyed Pea draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, black-eyed pea can only work that bloom inside Nebraska's frost window — roughly 181 days, opening after the last 28°F freeze (Apr 12 - Apr 26) and closing at the first (Oct 15 - Oct 21), per NOAA Regional Climate Centers ACIS, 1991-2020.
Nebraska Cooperative Extension
For Nebraska-specific cultivar recommendations, planting calendars, and pest pressure for black-eyed pea, the canonical source is Nebraska Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Black-Eyed Pea native to Nebraska?
No — the USDA PLANTS Database lists Black-Eyed Pea as introduced rather than native in the Lower 48, so it is not part of Nebraska's native flora. It grows here as a garden plant; pairing it with a few Nebraska natives keeps local pollinators fed too.

Common Questions About Growing Black-Eyed Pea in Nebraska
When can I plant Black-Eyed Pea in Nebraska?
Nebraska's last spring hard freeze (28°F) clears between Apr 12 and Apr 26, and the first fall hard freeze lands between Oct 15 and Oct 21 (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 Black-Eyed Pea mature before first frost in Nebraska?
Yes — Black-Eyed Pea matures in 70 days (Growable Ground Plant Database), and Nebraska's dependable hard-freeze-free window runs 172 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 102 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 Black-Eyed Pea grown in across Nebraska?
Nebraska spans USDA hardiness zones 4b-6a (USDA ARS PHZM 2023). Black-Eyed Pea carries a range of zones 3-12, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Nebraska site have?
A typical Nebraska site sees ~181 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Black-Eyed Pea needs 30+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Black-Eyed Pea native to Nebraska?
No — the USDA PLANTS Database lists Black-Eyed Pea as introduced rather than native in the Lower 48, so it is not part of Nebraska's native flora. It grows here as a garden plant; pairing it with a few Nebraska natives keeps local pollinators fed too.
How should I amend the soil for Black-Eyed Pea in Nebraska?
Black-Eyed Pea tolerates pH 4-8.8 and well (dry spells) drainage (FAO ECOCROP). That is a 4.8-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a Nebraska site — amend for drainage and organic matter first.
