Unlikely — Zone Mismatch
pothos (zones 10-12) does not overlap with Arkansas's zone range (6b-8b). Growing outdoors is unlikely without significant protection.
2 zones short — what would close it
Pothos is hardy to zone 10, and the warmest ground in Arkansas is zone 8 — 2 zones short. Planted in open ground it will not survive a Arkansas winter. To grow it here, grow pothos in an earth-sheltered greenhouse — its modeled 2.5-zone lift covers this gap.

Arkansas is not one climate
Arkansas’s winter-low ladder runs across 75 counties, from zone 7 in Benton County to zone 8.5 in Union County. That is 15°F between the two counties’ average coldest night — the difference between pothos overwintering in the ground and coming under cover.
The middle half of 75 counties runs 7.5–8 zones, with a median of 8 zones — a 1.5-zone span end to end.

Where Pothos Stands in Arkansas
Pothos is rated for zones 10–12 — a cold floor USDA puts at 30 to 40°F. No Arkansas county sits inside it, so in open ground this is a grown-under-cover plant here rather than a bed plant — which is a statement about Arkansas winters, not about pothos.

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.

When to Plant Pothos in Arkansas
The frost window
Across Arkansas, the last spring hard freeze (28°F) clears between Mar 2 and Mar 20, and the first fall hard freeze lands between Nov 15 and Nov 23 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 240-day window you can count on — up to 266 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
Arkansas runs as cold as USDA zone 6, and no sourced winter-hardiness floor is on record for pothos, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether pothos is a permanent planting or a replant-every-spring crop for you turns on your own zone within Arkansas; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Carroll County, not the statewide average.
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.
Soil + Drainage Fit
Pothos likes near-neutral soil (pH 5.5-7). That's the common-ground band across Arkansas's silt loam 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 6.5 — worth knowing before you decide whether a Arkansas soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Arkansas site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost. pH range, preferred pH and drainage need: We haven't confirmed this against a published source yet.
Your land, not the state average
SSURGO maps about 33.9% of Arkansas as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Pothos sits mid-range for drought tolerance, so either extreme can cost you — your soil map unit, not the state average, is the real answer.

What Else to Consider for Pothos in Arkansas
Zone compatibility tells you about winter cold survival — but Arkansas growers also need to think about:
Hot, humid summers drive fungal and bacterial diseases
Heavy clay soils in parts of the Ozarks
Severe spring storms and hail risk
Growing pothos here specifically
Pothos rates to USDA zones 10–12 and takes frost damage on growing tissue around 50°F (FAO ECOCROP), but cold isn't the risk in Arkansas — wet is: with roughly 33.9% of its soils poorly-drained (SSURGO), soggy ground rots the crown.
Give pothos a raised bed or mounded row with coarse amendment so its crown never sit wet. How to handle it →
What to actually do about these — and the constraints that apply to every Arkansas grower, not just pothos — is covered on the Arkansas growing guide.
Timing shifts within Arkansas
Arkansas isn't one climate. In Carroll County, the last hard freeze (28°F) holds until about Mar 26 — roughly 16 days later than the recorded state median — so plant pothos to your county's window, not the statewide date.
County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.
Where in Arkansas Pothos Is Zone-Hardy
Pothos is rated for USDA zones 10–12. No Arkansas county reaches it. Even Union County, the state’s mildest winter at zone 8b, sits below the plant’s zone 10 floor — so in open ground this one needs winter protection here, or a container that comes under cover.
Across those 75 counties Arkansas’s winter-low ladder runs from zone 7a in Benton County to zone 8b in Union County — 1.5 USDA zones of spread, which is 15°F between the two counties’ average coldest night of the year. None of that range reaches the band pothos needs, so here the statewide answer really is the answer.

Good to Know Before You Plant Pothos
Pothos is listed as toxic to dogs, cats (all) at a moderate level. (Source: NC State Extension Gardener Plant Toolbox; U.S. FDA Center for Veterinary Medicine, which lists this plant as potentially dangerous to pets.) Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear. Parts of pothos carry moderate toxicity for people, so know which parts are edible before harvest.
Arkansas Cooperative Extension
For Arkansas-specific cultivar recommendations, planting calendars, and pest pressure for pothos, the canonical source is University of Arkansas Cooperative Extension Service. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Pothos native to Arkansas?
No — the USDA PLANTS Database lists Pothos as introduced rather than native in the Lower 48, so it is not part of Arkansas's native flora. It grows here as a garden plant; pairing it with a few Arkansas natives keeps local pollinators fed too.
Looking for plants that belong here? The Arkansas growing guide lists plants that USDA PLANTS records growing in Arkansas 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 Pothos in Arkansas
When can I plant Pothos in Arkansas?
Arkansas's last spring hard freeze (28°F) clears between Mar 2 and Mar 20, and the first fall hard freeze lands between Nov 15 and Nov 23 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Pothos, so this page does not state whether it overwinters in Arkansas 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 Pothos grown in across Arkansas?
Arkansas spans USDA hardiness zones 6b-8b (USDA ARS PHZM 2023). Pothos is listed for zones 10-12, which do not overlap them, so there is no zone in Arkansas where this page can call outdoor growing reliable. A parcel report resolves your own address's zone.
How many frost-free days does a typical Arkansas site have?
A typical Arkansas site sees ~254 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Pothos needs 365+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Carroll, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Pothos native to Arkansas?
No — the USDA PLANTS Database lists Pothos as introduced rather than native in the Lower 48, so it is not part of Arkansas's native flora. It grows here as a garden plant; pairing it with a few Arkansas natives keeps local pollinators fed too.
How should I amend the soil for Pothos in Arkansas?
Pothos prefers pH 5.5-7 and well (dry spells) drainage. We haven't confirmed this against a published source yet. That sits in the common-ground band across Arkansas soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Pothos actually grow on my specific land in Arkansas?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores pothos against your address's mapped soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
