Your yard isn't the whole zone.

Frisee 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 frisee 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 frisee can finish before the first hard freeze.

When to Plant Frisee 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.

Frost hardiness

Frisee takes cold down to about 25°F before a freeze kills it (FAO ECOCROP), so you can plant on the early side of Nebraska'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.

When to start the seed

Those dates are when frisee goes out, not when it starts. It is sown under cover about 4 weeks ahead, so counting back from Nebraska's late-side last freeze of Apr 26 is what fixes your sowing date — and a yard that clears frost earlier than the state's late date starts earlier still.

Days to maturity vs. the window

At 50 days to maturity (Growable Ground Plant Database), counting from the last hard freeze it ripens with 122 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 frisee survives winter here. Whether the season is long enough — and warm enough — is a different question.

Frost-free days

Frisee wants 50+ 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

Frisee needs ~900 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

Frisee likes near-neutral soil (pH 5-7). That's the common-ground band across Nebraska's loess and sandy loam (sandhills) — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6 and 6.8 — 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.

Drainage: FAO ECOCROP, with the remaining rows from other published sources or Growable Ground compilation. Nebraska soil profile from USDA NRCS SSURGO. Site-specific verification: a 30-minute soil test from your local Extension lab.

Before you plant frisee 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 frisee 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.

Federal record: High

We checked the federal record across Nebraska10,663 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.

A note from Gnorman

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, USGS1.8M documented sites tracked nationwide across 9 federal source types.

What Else to Consider for Frisee 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 frisee — is covered on the Nebraska growing guide.

Timing shifts within Nebraska

Frisee needs about 50 days of frost-free season to complete its cycle. Even Sioux County — Nebraska’s shortest season at 134 frost-free days — clears that by 84 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 frisee about 131 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"). Frisee's 50-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

Frisee draws honeybees (low value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, frisee 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 frisee, the canonical source is Nebraska Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.

Is Frisee native to Nebraska?

No — the USDA PLANTS Database lists Frisee 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 Frisee in Nebraska

When can I plant Frisee 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). Frisee takes cold to about 25°F before a freeze kills it (FAO ECOCROP — the point where cold damages growing tissue, not a winter-survival floor), so plant on the early side of that window — even ahead of the final hard freeze.

Can Frisee mature before first frost in Nebraska?

Yes — Frisee matures in 50 days (Growable Ground Plant Database), and Nebraska's dependable hard-freeze-free window runs 172 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 122 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 Frisee grown in across Nebraska?

Nebraska spans USDA hardiness zones 4b-6a (USDA ARS PHZM 2023). Frisee carries a range of zones 4-9, 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). Frisee needs 50+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.

Is Frisee native to Nebraska?

No — the USDA PLANTS Database lists Frisee 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 Frisee in Nebraska?

Frisee prefers pH 5-7 and well (dry spells) drainage (Growable Ground Plant Database). That sits in the common-ground band across Nebraska soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
