Nebraska is not one climate
Nebraska’s winter-low ladder runs across 93 counties, from zone 4.5 in Sioux County to zone 6 in Thayer County. That is 15°F between the two counties’ average coldest night — the difference between catnip overwintering in the ground and coming under cover.
The middle half of 93 counties runs 5–5.5 zones, with a median of 5.5 zones — a 1.5-zone span end to end.

When to Plant Catnip 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
Those dates are when catnip goes out, not when it starts. It is sown under cover about 6 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.
Winter standing
Nebraska runs as cold as USDA zone 4, and no sourced winter-hardiness floor is on record for catnip, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether catnip is a permanent planting or a replant-every-spring crop for you turns on your own zone within Nebraska; check its hardiness range against that before treating it as long-lived ground.
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 catnip survives winter here. Whether the season is long enough — and warm enough — is a different question.
Growing degree days
Catnip needs ~800 GDD (base 50°F) to ripen. We haven't confirmed this against a published source yet. 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
Catnip likes near-neutral soil (pH 4.9-7.5). 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 5.5 and 6.5 — 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, a raised bed lifts the roots above wet ground, or work in compost. Drainage need: We haven't confirmed this against a published source yet.

Before you plant catnip 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 catnip 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 — 4,007 documented sites across 7 of the 8 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 of imported, lab-tested 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 Superfund (162 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.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).
Sources: EPA, USGS — 950K documented sites tracked nationwide across 8 federal source types.
What Else to Consider for Catnip 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 catnip — is covered on the Nebraska growing guide.
Where in Nebraska Catnip Is Zone-Hardy
Catnip is rated for USDA zones 3–9. Every one of Nebraska’s 93 counties sits inside that band — from Sioux County at zone 4b to Thayer County at zone 6a — so winter cold is not what decides this plant anywhere in the state. What is left to vary is your own parcel: slope, shelter and cold-air drainage routinely move a site half a zone either way from the county figure.
Across those 93 counties Nebraska’s winter-low ladder runs from zone 4b in Sioux County to zone 6a in Thayer County — 1.5 USDA zones of spread, which is 15°F between the two counties’ average coldest night of the year. That is why a statewide hardiness answer is where you start and not where you finish.
The planting window moves with it. Sioux County holds its last hard freeze (28°F) until about May 14, while Douglas County is clear by Apr 5 — 39 days apart. Set catnip out on your county’s date, not the state’s.

County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F killing freeze — earlier than the folk 32°F "last frost".

Pollinator + Wildlife Value
Catnip draws honeybees, native bees, and butterflies (high value). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, catnip 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. Pollinator value: We haven't confirmed this against a published source yet.

Is Catnip native to Nebraska?
No — the USDA PLANTS Database lists Catnip 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.
Looking for plants that belong here? The Nebraska growing guide lists plants that USDA PLANTS records growing in Nebraska and that Kew and NatureServe Explorer both list in its native range, leaving out any that NatureServe flags as exotic there or that our audit holds.

Common Questions About Growing Catnip in Nebraska
When can I plant Catnip 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). No sourced winter-hardiness floor is on record for Catnip, so this page does not state whether it overwinters in Nebraska 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 Catnip grown in across Nebraska?
Nebraska spans USDA hardiness zones 4b-6a (USDA ARS PHZM 2023). Catnip carries a range of zones 3-9, 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). Catnip needs 150+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Catnip native to Nebraska?
No — the USDA PLANTS Database lists Catnip 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 Catnip in Nebraska?
Catnip prefers pH 4.9-7.5 and well (dry spells) drainage. We haven't confirmed this against a published source yet. 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.
