Florida is not one climate
Florida’s winter-low ladder runs across 67 counties, from zone 8.5 in Holmes County to zone 10.5 in Palm Beach County. That is 20°F between the two counties’ average coldest night — the difference between cinnamon overwintering in the ground and coming under cover.
The middle half of 67 counties runs 9–10 zones, with a median of 9.5 zones — a 2-zone span end to end.

Where in Florida Fits Best
Cinnamon is rated for zones 10–12 — a cold floor USDA puts at 30 to 40°F. Against Florida’s 67 counties that band holds in 20 of them, and the line runs at Brevard County (zone 10a), the coldest county still inside 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 Florida's zones 8b-12a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for cinnamon (USDA PHZM 2023):

When to Plant Cinnamon in Florida
The frost window
Across Florida, the last spring hard freeze (28°F) clears between Jan 25 and Feb 10, and the first fall hard freeze lands between Dec 7 and Dec 18 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 300-day window you can count on — up to 327 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 Florida runs as cold as zone 8, 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 Florida — which is why this page gives neither. What it needs here is a way through winter, not a planting date.
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.
Growing Season Fit
The zone check says cinnamon survives winter in part of Florida, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Cinnamon wants 300+ frost-free days; a typical Florida site sees ~320 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a workable window — start indoors to bank time.
Growing degree days
Cinnamon needs ~5000 GDD (base 50°F) to ripen. The state median runs ~7743 GDD (from PRISM 1991-2020 climate normals), so Florida'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
Cinnamon likes near-neutral soil (pH 5-7). That's the common-ground band across Florida's sandy and muck (everglades) — 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 Florida soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Florida site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

Drainage: FAO ECOCROP, with the remaining rows from other published sources or Growable Ground compilation. Florida soil profile from USDA NRCS SSURGO. Site-specific verification: a 30-minute soil test from your local Extension lab.
Before you plant cinnamon for food
Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before cinnamon goes in. What follows is Florida’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.
Safe to Grow Here?
What the federal record shows across Florida — and how to grow with it.
We checked the federal record across Florida — 76,189 documented sites across 7 of the 9 source types we track.
The most significant on record: 602 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Florida carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

Highest-Severity Sites
Know Before You Grow
- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
- •Near a brownfield, raised beds of imported soil give your food clean ground.
- •On a private well, test for nitrates: above 10 mg/L the water needs treatment before irrigating.

What Else to Consider for Cinnamon in Florida
Zone compatibility tells you about winter cold survival — but Florida growers also need to think about:
Sandy soils drain too fast and hold few nutrients — frequent fertilization needed
Humidity drives fungal diseases (powdery mildew, black spot, rust)
Hurricane season (June-November) can destroy plantings
Nematodes are a serious pest in sandy FL soils
What to actually do about these — and the constraints that apply to every Florida grower, not just cinnamon — is covered on the Florida growing guide.
Timing shifts within Florida
Cinnamon needs about 300 days of frost-free season to complete its cycle. 51 of Florida’s 67 counties give it that outright. The tightest that does is Clay County at 300 frost-free days — 0 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
Across Florida’s 67 counties the frost-free season runs from 281 days in Holmes County to 365 days in Sarasota County — a spread of 84 days, which is why a single statewide planting date misleads. The median Florida county sees 320 frost-free days, leaving cinnamon about 20 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"). 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 Florida's frost window — roughly 320 days, opening after the last 28°F freeze (Jan 25 - Feb 10) and closing at the first (Dec 7 - Dec 18), per NOAA Regional Climate Centers ACIS, 1991-2020.
Florida Cooperative Extension
For Florida-specific cultivar recommendations, planting calendars, and pest pressure for cinnamon, the canonical source is UF/IFAS Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Cinnamon native to Florida?
No — the USDA PLANTS Database lists Cinnamon as introduced rather than native in the Lower 48, so it is not part of Florida's native flora. It grows here as a garden plant; pairing it with a few Florida natives keeps local pollinators fed too.

Common Questions About Growing Cinnamon in Florida
When can I plant Cinnamon in Florida?
Florida's last spring hard freeze (28°F) clears between Jan 25 and Feb 10, and the first fall hard freeze lands between Dec 7 and Dec 18 (NOAA Regional Climate Centers ACIS, 1991-2020). Cinnamon overwinters only from USDA zone 10 and warmer, and Florida runs as cold as zone 8, so it does not survive winter in the ground here — the question for Florida growers is how to carry it through winter under cover, not which week to plant it.
What hardiness zone is Cinnamon grown in across Florida?
Florida spans USDA hardiness zones 8b-12a (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 Florida site have?
A typical Florida site sees ~320 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.
Is Cinnamon native to Florida?
No — the USDA PLANTS Database lists Cinnamon as introduced rather than native in the Lower 48, so it is not part of Florida's native flora. It grows here as a garden plant; pairing it with a few Florida natives keeps local pollinators fed too.
How should I amend the soil for Cinnamon in Florida?
Cinnamon prefers pH 5-7 and well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Florida soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
