Generally — Most Areas
winter savory (zones 5-8) suits most of Nevada (4a-10a) — zones 5-8 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
Nevada spans zones 4a-10a, 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 Nevada
The frost window
Across Nevada, the last spring hard freeze (28°F) clears between Apr 28 and May 20, and the first fall hard freeze lands between Oct 9 and Oct 21 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 142-day window you can count on — up to 176 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 Nevada's late-side last freeze of May 20 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 Nevada 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 Nevada — 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 Nevada, 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 Nevada site sees ~163 (NOAA Regional Climate Centers ACIS, 1991-2020) — 47 days short of what it needs. A typical Nevada 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 ~1725 GDD (from PRISM 1991-2020 climate normals), so Nevada'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 Nevada's desert sand and caliche — 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 Nevada soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Nevada 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 Nevada
Zone compatibility tells you about winter cold survival — but Nevada growers also need to think about:
Extremely low rainfall (driest US state)
Alkaline soils (pH 8-9) limit many species
Extreme summer heat in southern valleys
What to actually do about these — and the constraints that apply to every Nevada grower, not just winter savory — is covered on the Nevada growing guide.
Timing shifts within Nevada
Winter Savory needs about 210 days of frost-free season to complete its cycle. 1 of Nevada’s 17 counties give it that outright. The tightest that does is Clark County at 321 frost-free days — 111 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
Across Nevada’s 17 counties the frost-free season runs from 110 days in Elko County to 321 days in Clark County — a spread of 211 days, which is why a single statewide planting date misleads. The median Nevada county sees 163 frost-free days, which is 47 days short of what winter savory needs — so on a typical Nevada 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 Nevada Fits Best
Even within Nevada's zones 4a-10a, 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 Nevada's frost window — roughly 163 days, opening after the last 28°F freeze (Apr 28 - May 20) and closing at the first (Oct 9 - Oct 21), per NOAA Regional Climate Centers ACIS, 1991-2020.
Nevada Cooperative Extension
For Nevada-specific cultivar recommendations, planting calendars, and pest pressure for winter savory, the canonical source is University of Nevada, Reno Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Winter Savory native to Nevada?
No — the USDA PLANTS Database lists Winter Savory as introduced rather than native in the Lower 48, so it is not part of Nevada's native flora. It grows here as a garden plant; pairing it with a few Nevada natives keeps local pollinators fed too.

Common Questions About Growing Winter Savory in Nevada
When can I plant Winter Savory in Nevada?
Nevada's last spring hard freeze (28°F) clears between Apr 28 and May 20, and the first fall hard freeze lands between Oct 9 and Oct 21 (NOAA Regional Climate Centers ACIS, 1991-2020). Winter Savory overwinters only from USDA zone 5 and warmer, and Nevada runs as cold as zone 4, so it does not survive winter in the ground here — the question for Nevada 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 Nevada?
Nevada spans USDA hardiness zones 4a-10a (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 Nevada site have?
A typical Nevada site sees ~163 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 Nevada?
No — the USDA PLANTS Database lists Winter Savory as introduced rather than native in the Lower 48, so it is not part of Nevada's native flora. It grows here as a garden plant; pairing it with a few Nevada natives keeps local pollinators fed too.
How should I amend the soil for Winter Savory in Nevada?
Winter Savory prefers pH 6-7.5 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Nevada soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
