Generally — Most Areas

Your yard isn't the whole zone.
Georgia spans zones 7a-9b, 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 peony against your land's actual soil, sun, and frost.

Georgia is not one climate
A single Georgia answer averages 159 counties whose growing seasons are 101 days apart — from 204 frost-free days in Towns County to 305 in Colquitt County. Which end of that your land sits nearer changes what peony can finish before the first hard freeze.
The middle half of 159 counties runs 259–290 days, with a median of 275 days — a 101-day span end to end.
Measured across 159 Georgia counties. NOAA Regional Climate Centers ACIS, 1991-2020, county 28°F killing freeze. 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 Georgia Fits Best
Peony is rated for zones 3–8 — a cold floor USDA puts at -40 to -30°F. Against Georgia’s 159 counties that band holds in 44 of them, and the line runs at Fannin County (zone 7b), 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 Georgia's zones 7a-9b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for peony (USDA PHZM 2023):

When to Plant Peony in Georgia
The frost window
Across Georgia, the last spring hard freeze (28°F) clears between Feb 17 and Mar 10, and the first fall hard freeze lands between Nov 24 and Dec 4 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 259-day window you can count on — up to 290 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.
What Else to Consider for Peony in Georgia
Zone compatibility tells you about winter cold survival — but Georgia growers also need to think about:
Heavy red Piedmont clay is difficult to work and drains poorly
High humidity drives fungal diseases in summer
Fire ants are a persistent pest in gardens across the state
Summer heat (90-100F) can stress cool-season crops by May
What to actually do about these — and the constraints that apply to every Georgia grower, not just peony — is covered on the Georgia growing guide.
Where in Georgia Peony Is Zone-Hardy
Peony is rated for USDA zones 3–8. 44 of Georgia’s 159 counties fall inside that band. The coldest that does is Fannin County at zone 7b. 115 counties sit above its zone 8 ceiling, where the limit is too little winter chill rather than too much cold. Where you are in Georgia decides this one.
Across those 159 counties Georgia’s winter-low ladder runs from zone 7b in Fannin County to zone 9a in Worth 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. Union County holds its last hard freeze (28°F) until about Apr 7, while Worth County is clear by Feb 7 — 59 days apart. Set peony 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". Peony’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
Peony draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, peony can only work that bloom inside Georgia's frost window — roughly 275 days, opening after the last 28°F freeze (Feb 17 - Mar 10) and closing at the first (Nov 24 - Dec 4), per NOAA Regional Climate Centers ACIS, 1991-2020. Deer pressure is meaningful across much of Georgia; peony is listed as deer-resistant (USDA PLANTS Database), which makes it a safer pick for unfenced sites. Our deer & wildlife guide carries the full deer-resistant list and how to protect the rest.

Common Questions About Growing Peony in Georgia
When can I plant Peony in Georgia?
Georgia's last spring hard freeze (28°F) clears between Feb 17 and Mar 10, and the first fall hard freeze lands between Nov 24 and Dec 4 (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 Peony grown in across Georgia?
Georgia spans USDA hardiness zones 7a-9b (USDA ARS PHZM 2023). Peony 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 Georgia site have?
A typical Georgia site sees ~275 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Peony 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.
Will Peony actually grow on my specific land in Georgia?
