Yes — Strong Match
caraway (zones 3-7) covers every zone Nebraska contains (4b-6a), so hardiness is not what limits it anywhere in the state.
Your yard isn't the whole zone.
Nebraska spans zones 4b-6a, 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 caraway against your land's actual soil, sun, and frost.

When to Plant Caraway 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 tenderness
Caraway is frost-tender — its listed minimum temperature is 44.6°F (USDA PLANTS Database) — so set plants out two to three weeks PAST your local last hard freeze, not on it and not on the state's earliest date. The 28°F marker above is when killing freezes stop, not when light frost does.
When to start the seed
Caraway 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 240 days to maturity (USDA PLANTS Database), even Nebraska's kindest 192-day season runs short — challenging without season extension. An indoor start plus row cover on both shoulders of the season closes the gap.
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 caraway survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Caraway wants 150+ frost-free days; a typical Nebraska site sees ~181 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a workable window — start indoors to bank time.
Growing degree days
Caraway needs ~1500 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
Caraway tolerates a wide pH range (pH 4.8-7.8) — 3 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 6 and 7 — 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.

What Else to Consider for Caraway 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 caraway — is covered on the Nebraska growing guide.
Timing shifts within Nebraska
Caraway needs about 150 days of frost-free season to complete its cycle. 92 of Nebraska’s 93 counties give it that outright. The tightest that does is Banner County at 157 frost-free days — 7 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
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 caraway about 31 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"). Caraway's 150-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in Nebraska Fits Best
Even within Nebraska's zones 4b-6a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for caraway (USDA PHZM 2023):
Pollinator + Wildlife Value
Caraway draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, caraway 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.

Common Questions About Growing Caraway in Nebraska
When can I plant Caraway 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). Caraway is frost-tender — its listed minimum temperature is 44.6°F (USDA PLANTS Database) — so wait two to three weeks past your site's last hard freeze, when light frost has also stopped, before planting out.
Can Caraway mature before first frost in Nebraska?
Caraway needs 240 days to mature (USDA PLANTS Database), and even Nebraska's longest typical season runs 192 days (NOAA Regional Climate Centers ACIS, 1991-2020) — challenging without season extension. An indoor start plus row cover on both season shoulders closes the gap.
What hardiness zone is Caraway grown in across Nebraska?
Nebraska spans USDA hardiness zones 4b-6a (USDA ARS PHZM 2023). Caraway carries a range of zones 3-7, 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). Caraway needs 150+ 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 Caraway in Nebraska?
Caraway tolerates pH 4.8-7.8 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 Nebraska site — amend for drainage and organic matter first.
Will Caraway actually grow on my specific land in Nebraska?
