Unlikely — Zone Mismatch
cinnamon (zones 10-12) does not overlap with Georgia's zone range (7a-9b). Growing outdoors is unlikely without significant protection.
One zone short — what would close it
Cinnamon is hardy to zone 10, and the warmest ground in Georgia is zone 9 — 1 zone short. Planted in open ground it will not survive a Georgia winter. To grow it here, grow cinnamon in a container and move it under cover for the coldest weeks, or give it a greenhouse.

When to Plant Cinnamon 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.
Winter standing
Cinnamon overwinters from USDA zone 10 and warmer (NC State Extension Gardener Plant Toolbox; Missouri Botanical Garden Plant Finder), and Georgia runs as cold as zone 7, so it does not survive winter in the ground here. It is a woody plant rather than a crop you resow each spring, so neither a fall establishment date nor a harvest countdown describes it in Georgia — which is why this page gives neither. What it needs here is a way through winter, not a planting date.
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 cinnamon does not survive a Georgia winter in the ground. The season figures below measure a different question — whether it could finish a season here at all — and they only bear on Georgia under protection.
Frost-free days
Cinnamon wants 300+ frost-free days; a typical Georgia site sees ~275 (NOAA Regional Climate Centers ACIS, 1991-2020) — 25 days short of what it needs. A typical Georgia season does not carry this crop to harvest outdoors, and a gap that size is not one an earlier sowing date or a faster cultivar closes; growing it here means growing it under cover.
Growing degree days
Cinnamon needs ~5000 GDD (base 50°F) to ripen. The state median runs ~5616 GDD (from PRISM 1991-2020 climate normals), so Georgia sits right at the threshold — pay attention to siting and microclimate.
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
Cinnamon likes near-neutral soil (pH 5-7). 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 5.5 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. Cinnamon has low drought tolerance, so it is the fast-draining end that will cost you — your soil map unit, not the state average, is the real answer.

What Else to Consider for Cinnamon 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 cinnamon here specifically
Cinnamon roots run deep and prefer pH 5.0–7.0, but drainage comes first here: SSURGO maps about 20.4% of Georgia as poorly or somewhat-poorly drained, and wet ground rots its crown before pH ever matters.
Plant cinnamon on a raised, gravel-amended berm so water drains fast and the crown stays dry. How to handle it →
What to actually do about these — and the constraints that apply to every Georgia grower, not just cinnamon — 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 cinnamon to your county's window, not the statewide date.
Cinnamon needs about 300 days of frost-free season to complete its cycle. 11 of Georgia’s 159 counties give it that outright. The tightest that does is McIntosh County at 300 frost-free days — 0 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
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, which is 25 days short of what cinnamon needs — so on a typical Georgia parcel this is a transplant-or-protect crop, not a direct-sow one.
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"). Cinnamon's 300-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Cinnamon draws honeybees (low value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, cinnamon 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.
Good to Know Before You Plant Cinnamon
Cinnamon is listed as toxic to dogs, cats (bark) at a mild level (Pet Poison Helpline). Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear. Worth knowing for placement: cinnamon is woody and hardy only from zone 10, against a Georgia low of zone 7, so it is overwintered under cover here rather than left standing outside — which is where it will be in reach.
Recommended Cinnamon Varieties for Georgia
Georgia publishes no state variety trial for cinnamon, 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 cinnamon, the canonical source is UGA Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Cinnamon native to Georgia?
No — the USDA PLANTS Database lists Cinnamon 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 Cinnamon in Georgia
When can I plant Cinnamon 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). Cinnamon overwinters only from USDA zone 10 and warmer, and Georgia runs as cold as zone 7, so it does not survive winter in the ground here — the question for Georgia growers is how to carry it through winter under cover, not which week to plant it.
What hardiness zone is Cinnamon grown in across Georgia?
Georgia spans USDA hardiness zones 7a-9b (USDA ARS PHZM 2023). Cinnamon carries a range of zones 10-12, 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). Cinnamon needs 300+ 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 Cinnamon native to Georgia?
No — the USDA PLANTS Database lists Cinnamon 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 Cinnamon in Georgia?
Cinnamon prefers pH 5-7 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.
