Oklahoma is not one climate
Oklahoma’s winter-low ladder runs across 77 counties, from zone 6.5 in Beaver County to zone 8 in Tillman County. That is 15°F between the two counties’ average coldest night — the difference between lingonberry overwintering in the ground and coming under cover.
The middle half of 77 counties runs 7–7.5 zones, with a median of 7.5 zones — a 1.5-zone span end to end.

Where in Oklahoma Fits Best
Lingonberry is rated for zones 1–7 — a cold floor USDA puts at -60 to -50°F. Against Oklahoma’s 77 counties that band holds in 27 of them, and the line runs at Beaver County (zone 6b), the coldest county still inside it.

Too little winter chill rather than too much cold — a low-chill selection is what changes it.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. A zone is a 10°F band of average annual extreme minimum temperature, so the floor above is the band the plant's rating denotes, not a single measured kill point. Slope, shelter and cold-air drainage routinely move a site half a zone either way from its county figure — which is the part only your address resolves.
Even within Oklahoma's zones 6b-8b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for lingonberry (USDA PHZM 2023):

When to Plant Lingonberry 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.
Winter standing
Oklahoma runs as cold as USDA zone 6, and no sourced winter-hardiness floor is on record for lingonberry, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether lingonberry is a permanent planting or a replant-every-spring crop for you turns on your own zone within Oklahoma; 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 lingonberry survives winter in part of Oklahoma, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Growing degree days
Lingonberry needs ~1200 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.
Chill hours
Lingonberry requires ~800 chill hours (32-45°F dormancy window). Oklahoma typically banks ~1955 chill hours per winter (from PRISM 1991-2020 climate normals), which keeps this plant on track.
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
Lingonberry likes near-neutral soil (pH 4.5-6). 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 4.2 and 5.5 — 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.

Before you plant lingonberry 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 lingonberry goes in. What follows is Oklahoma’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 Oklahoma — and how to grow with it.
We checked the federal record across Oklahoma — 24,720 documented sites across 8 of the 9 source types we track.
The most significant on record: 151 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Oklahoma 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 with clean imported soil grow well almost anywhere in the meantime.

What Else to Consider for Lingonberry 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 lingonberry — is covered on the Oklahoma growing guide.
Where in Oklahoma Lingonberry Is Zone-Hardy
Lingonberry is rated for USDA zones 1–7. 27 of Oklahoma’s 77 counties fall inside that band. The coldest that does is Beaver County at zone 6b. 50 counties sit above its zone 7 ceiling, where the limit is too little winter chill rather than too much cold. Where you are in Oklahoma decides this one.
Across those 77 counties Oklahoma’s winter-low ladder runs from zone 6b in Beaver County to zone 8a in Tillman 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. Cimarron County holds its last hard freeze (28°F) until about Apr 13, while Choctaw County is clear by Mar 1 — 43 days apart. Set lingonberry out on your county’s date, not the state’s.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F killing freeze — earlier than the folk 32°F "last frost". Lingonberry’s zone 1–7 band: USDA PLANTS / Growable Ground plant database. A parcel report resolves your address’s own zone and frost dates rather than its county’s.
Pollinator + Wildlife Value
Lingonberry draws honeybees and native bees (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, lingonberry 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.

Common Questions About Growing Lingonberry in Oklahoma
When can I plant Lingonberry 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). No sourced winter-hardiness floor is on record for Lingonberry, so this page does not state whether it overwinters in Oklahoma 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 Lingonberry grown in across Oklahoma?
Oklahoma spans USDA hardiness zones 6b-8b (USDA ARS PHZM 2023). Lingonberry carries a range of zones 1-7, 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). Lingonberry should be matched against that window, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Lingonberry native to Oklahoma?
Lingonberry is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Oklahoma. It can still earn a place in a Oklahoma garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Lingonberry in Oklahoma?
Lingonberry prefers pH 4.5-6 and well (dry spells) drainage (USDA PLANTS). 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.
