Generally — Most Areas
winter savory (zones 5-8) suits most of Nebraska (4b-6a) — zones 5-6 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
Nebraska spans zones 4b-6a, but your yard sits in exactly one — and slope, tree cover, and cold-air pockets nudge it further. Enter your address and we'll score winter savory against your parcel's actual hardiness, soil, and sun.

When to Plant Winter Savory 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 winter savory goes out, not when it starts. It is sown under cover about 8 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
Winter Savory overwinters from USDA zone 5 and warmer (NC State Extension Gardener Plant Toolbox; Missouri Botanical Garden Plant Finder), and Nebraska runs as cold as zone 4, so it does not survive winter in the ground here. It is a woody plant rather than a crop you resow each spring, so neither a fall establishment date nor a harvest countdown describes it in Nebraska — which is why this page gives neither. What it needs here is a way through winter, not a planting date.
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 winter savory survives winter in part of Nebraska, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Winter Savory wants 210+ frost-free days; a typical Nebraska site sees ~181 (NOAA Regional Climate Centers ACIS, 1991-2020) — 29 days short of what it needs. A typical Nebraska season does not carry this crop to harvest outdoors, and a gap that size is not one an earlier sowing date or a faster cultivar closes; growing it here means growing it under cover.
Growing degree days
Winter Savory 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
Winter Savory likes near-neutral soil (pH 6-7.5). 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 6.5 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 Winter Savory 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 winter savory — is covered on the Nebraska growing guide.
Timing shifts within Nebraska
Winter Savory needs about 210 days of frost-free season to complete its cycle. No Nebraska county gives it that outdoors: even Sarpy County, the state’s longest season at 207 frost-free days, falls 3 days short — so it needs transplants, a short-season variety, or covered growing.
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, which is 29 days short of what winter savory needs — so on a typical Nebraska parcel this is a transplant-or-protect crop, not a direct-sow one.
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"). Winter Savory's 210-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 winter savory (USDA PHZM 2023):
Pollinator + Wildlife Value
Winter Savory draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, winter savory 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 winter savory, the canonical source is Nebraska Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Winter Savory native to Nebraska?
No — the USDA PLANTS Database lists Winter Savory 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 Winter Savory in Nebraska
When can I plant Winter Savory 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). Winter Savory overwinters only from USDA zone 5 and warmer, and Nebraska runs as cold as zone 4, so it does not survive winter in the ground here — the question for Nebraska growers is how to carry it through winter under cover, not which week to plant it.
What hardiness zone is Winter Savory grown in across Nebraska?
Nebraska spans USDA hardiness zones 4b-6a (USDA ARS PHZM 2023). Winter Savory carries a range of zones 5-8, 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). Winter Savory needs 210+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Winter Savory native to Nebraska?
No — the USDA PLANTS Database lists Winter Savory 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 Winter Savory in Nebraska?
Winter Savory prefers pH 6-7.5 and well (dry spells) drainage (FAO ECOCROP). 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.
