Yes — Strong Match
savory (zones 1-11) covers every zone Oklahoma contains (6b-8b), so hardiness is not what limits it anywhere in the state.
Your yard isn't the whole zone.
Oklahoma spans zones 6b-8b, 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 savory against your land's actual soil, sun, and frost.

When to Plant Savory in Oklahoma
The frost window
Across Oklahoma, the last spring hard freeze (28°F) clears between Mar 15 and Mar 26, and the first fall hard freeze lands between Nov 9 and Nov 14 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 228-day window you can count on — up to 244 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
Savory is frost-tender — its listed minimum temperature is 57.2°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
Those dates are when savory goes out, not when it starts. It is sown under cover about 4 weeks ahead, so counting back from Oklahoma's late-side last freeze of Mar 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 60 days to maturity (USDA PLANTS Database), counting from the last hard freeze it ripens with 168 days to spare even in Oklahoma's tightest freeze scenario — room for a later start or a second sowing.
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 savory survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Savory wants 100+ frost-free days; a typical Oklahoma site sees ~237 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Savory needs ~1000 GDD (base 50°F) to ripen. The state median runs ~4695 GDD (from PRISM 1991-2020 climate normals), so Oklahoma'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
Savory likes near-neutral soil (pH 5.5-8.2). That's the common-ground band across Oklahoma's red clay and sandy loam — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6 and 7 — worth knowing before you decide whether a Oklahoma soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Oklahoma site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Savory in Oklahoma
Zone compatibility tells you about winter cold survival — but Oklahoma growers also need to think about:
Extreme weather variability (tornadoes, ice storms, drought)
Red clay soils drain poorly in central OK
Low western rainfall requires irrigation
What to actually do about these — and the constraints that apply to every Oklahoma grower, not just savory — is covered on the Oklahoma growing guide.
Timing shifts within Oklahoma
Savory needs about 100 days of frost-free season to complete its cycle. Even Cimarron County — Oklahoma’s shortest season at 197 frost-free days — clears that by 97 days, so season length isn’t the constraint anywhere in Oklahoma. What varies is your own parcel.
Across Oklahoma’s 77 counties the frost-free season runs from 197 days in Cimarron County to 267 days in Choctaw County — a spread of 70 days, which is why a single statewide planting date misleads. The median Oklahoma county sees 237 frost-free days, leaving savory about 137 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"). Savory's 100-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in Oklahoma Fits Best
Even within Oklahoma's zones 6b-8b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for savory (USDA PHZM 2023):
Pollinator + Wildlife Value
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, savory can only work that bloom inside Oklahoma's frost window — roughly 237 days, opening after the last 28°F freeze (Mar 15 - Mar 26) and closing at the first (Nov 9 - Nov 14), per NOAA Regional Climate Centers ACIS, 1991-2020.
Oklahoma Cooperative Extension
For Oklahoma-specific cultivar recommendations, planting calendars, and pest pressure for savory, the canonical source is Oklahoma State University Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Savory native to Oklahoma?
No — the USDA PLANTS Database lists Savory as introduced rather than native in the Lower 48, so it is not part of Oklahoma's native flora. It grows here as a garden plant; pairing it with a few Oklahoma natives keeps local pollinators fed too.

Common Questions About Growing Savory in Oklahoma
When can I plant Savory in Oklahoma?
Oklahoma's last spring hard freeze (28°F) clears between Mar 15 and Mar 26, and the first fall hard freeze lands between Nov 9 and Nov 14 (NOAA Regional Climate Centers ACIS, 1991-2020). Savory is frost-tender — its listed minimum temperature is 57.2°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 Savory mature before first frost in Oklahoma?
Yes — Savory matures in 60 days (USDA PLANTS Database), and Oklahoma's dependable hard-freeze-free window runs 228 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 168 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 Savory grown in across Oklahoma?
Oklahoma spans USDA hardiness zones 6b-8b (USDA ARS PHZM 2023). Savory carries a range of zones 1-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Oklahoma site have?
A typical Oklahoma site sees ~237 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Savory needs 100+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Savory native to Oklahoma?
No — the USDA PLANTS Database lists Savory as introduced rather than native in the Lower 48, so it is not part of Oklahoma's native flora. It grows here as a garden plant; pairing it with a few Oklahoma natives keeps local pollinators fed too.
How should I amend the soil for Savory in Oklahoma?
Savory prefers pH 5.5-8.2 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Oklahoma soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
