Yes — Strong Match
hepatica (zones 3-8) covers every zone Arkansas contains (6b-8b), so hardiness is not what limits it anywhere in the state.

Your yard isn't the whole zone.
Arkansas 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 hepatica against your land's actual soil, sun, and frost.

Arkansas is not one climate
A single Arkansas answer averages 75 counties whose growing seasons are 58 days apart — from 226 frost-free days in Benton County to 284 in Lincoln County. Which end of that your land sits nearer changes what hepatica can finish before the first hard freeze.
The middle half of 75 counties runs 241–266 days, with a median of 254 days — a 58-day span end to end.

Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where in Arkansas Fits Best
Hepatica is rated for zones 3–8 — a cold floor USDA puts at -40 to -30°F. Against Arkansas’s 75 counties that band holds in 62 of them, and the line runs at Benton County (zone 7a), 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 Arkansas's zones 6b-8b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for hepatica (USDA PHZM 2023):

When to Plant Hepatica 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.
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
Hepatica likes near-neutral soil (pH 6-8.5). 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 6.5 and 8 — worth knowing before you decide whether a Arkansas soil test result is a problem or just a number.

What Else to Consider for Hepatica 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
What to actually do about these — and the constraints that apply to every Arkansas grower, not just hepatica — is covered on the Arkansas growing guide.
Where in Arkansas Hepatica Is Zone-Hardy
Hepatica is rated for USDA zones 3–8. 62 of Arkansas’s 75 counties fall inside that band. The coldest that does is Benton County at zone 7a. 13 counties sit above its zone 8 ceiling, where the limit is too little winter chill rather than too much cold. Where you are in Arkansas decides this one.
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. That is why a statewide hardiness answer is where you start and not where you finish.
The planting window moves with it. Carroll County holds its last hard freeze (28°F) until about Mar 26, while Chicot County is clear by Feb 19 — 35 days apart. Set hepatica 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". Hepatica’s zone 3–8 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
Hepatica draws native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, hepatica can only work that bloom inside Arkansas's frost window — roughly 254 days, opening after the last 28°F freeze (Mar 2 - Mar 20) and closing at the first (Nov 15 - Nov 23), per NOAA Regional Climate Centers ACIS, 1991-2020.

Common Questions About Growing Hepatica in Arkansas
When can I plant Hepatica 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). Time outdoor planting to after the last hard freeze for your specific site — a further two to three weeks for anything tender — and count back from those dates for transplant scheduling.
What hardiness zone is Hepatica grown in across Arkansas?
Arkansas spans USDA hardiness zones 6b-8b (USDA ARS PHZM 2023). Hepatica carries a range of zones 3-8, so the overlap zones are where outdoor growing is most reliable.
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). Hepatica 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.
How should I amend the soil for Hepatica in Arkansas?
Hepatica prefers pH 6-8.5 (FAO ECOCROP). 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 Hepatica actually grow on my specific land in Arkansas?
