Yes — Strong Match
celosia (zones 2-11) covers every zone Georgia contains (7a-9b), so hardiness is not what limits it anywhere in the state.
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 celosia against your land's actual soil, sun, and frost.

When to Plant Celosia 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 tenderness
Celosia is frost-tender — its listed minimum temperature is 68°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 celosia goes out, not when it starts. It is sown under cover about 4 weeks ahead, so counting back from Georgia's late-side last freeze of Mar 10 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 90 days to maturity (USDA PLANTS Database), counting from the last hard freeze it ripens with 169 days to spare even in Georgia's tightest freeze scenario — room for a later start or a second sowing.
Timing tuned to sub-state frost dates — Towns County, not the statewide average.
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 celosia survives winter here. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Celosia wants 30+ frost-free days; a typical Georgia site sees ~275 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Celosia needs ~1200 GDD (base 50°F) to ripen. The state median runs ~5616 GDD (from PRISM 1991-2020 climate normals), so Georgia'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
Celosia likes near-neutral soil (pH 5.5-7.5). That's the common-ground band across Georgia's red clay (piedmont) and sandy loam (coastal plain) — 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 Georgia soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Georgia site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
SSURGO maps about 20.4% of Georgia as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Celosia 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 Celosia 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
Growing celosia here specifically
Celosia rates to USDA zones 2–11 and is hardy to about 68°F, but cold isn't the risk in Georgia — wet is: with roughly 20.4% of its soils poorly-drained (SSURGO), soggy ground rots the roots.
Give celosia a raised bed or mounded row with coarse amendment so its roots never sit wet. How to handle it →
What to actually do about these — and the constraints that apply to every Georgia grower, not just celosia — is covered on the Georgia growing guide.
Timing shifts within Georgia
Georgia isn't one climate. In Towns County, the last hard freeze (28°F) holds until about Apr 7 — roughly 39 days later than the recorded state median — so plant celosia to your county's window, not the statewide date.
Celosia needs about 30 days of frost-free season to complete its cycle. Even Towns County — Georgia’s shortest season at 204 frost-free days — clears that by 174 days, so season length isn’t the constraint anywhere in Georgia. What varies is your own parcel.
Across Georgia’s 159 counties the frost-free season runs from 204 days in Towns County to 305 days in Colquitt County — a spread of 101 days, which is why a single statewide planting date misleads. The median Georgia county sees 275 frost-free days, leaving celosia about 245 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"). Celosia's 30-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in Georgia Fits Best
Even within Georgia's zones 7a-9b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for celosia (USDA PHZM 2023):
Pollinator + Wildlife Value
Celosia draws honeybees, native bees, and butterflies (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, celosia 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.
Recommended Celosia Varieties for Georgia
Georgia publishes no state variety trial for celosia, so we won't invent a "best for Georgia" list. Choose types rated to your USDA hardiness zone (7a-9b), and confirm winter survival and drainage against your own parcel.
Georgia Cooperative Extension
For Georgia-specific cultivar recommendations, planting calendars, and pest pressure for celosia, the canonical source is UGA Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Celosia native to Georgia?
No — the USDA PLANTS Database lists Celosia as introduced rather than native in the Lower 48, so it is not part of Georgia's native flora. It grows here as a garden plant; pairing it with a few Georgia natives keeps local pollinators fed too.

Common Questions About Growing Celosia in Georgia
When can I plant Celosia 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). Celosia is frost-tender — its listed minimum temperature is 68°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 Celosia mature before first frost in Georgia?
Yes — Celosia matures in 90 days (USDA PLANTS Database), and Georgia's dependable hard-freeze-free window runs 259 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 169 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 Celosia grown in across Georgia?
Georgia spans USDA hardiness zones 7a-9b (USDA ARS PHZM 2023). Celosia carries a range of zones 2-11, 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). Celosia needs 30+ 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 Towns, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Celosia native to Georgia?
No — the USDA PLANTS Database lists Celosia as introduced rather than native in the Lower 48, so it is not part of Georgia's native flora. It grows here as a garden plant; pairing it with a few Georgia natives keeps local pollinators fed too.
How should I amend the soil for Celosia in Georgia?
Celosia prefers pH 5.5-7.5 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Georgia soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
