Conditional — Some Areas
Atlantic white cedar (zones 4-8) reaches only part of Florida (8b-12a): zone 8 are in range, so where you are in the state decides it.

Florida spans zones 8b-12a, but your yard sits in exactly one — and slope, tree cover, and cold-air pockets nudge it further. Enter your address and we'll score atlantic white cedar against your parcel's actual hardiness, soil, and sun.

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 atlantic white cedar 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 Atlantic White Cedar Stands in Florida
Atlantic White Cedar is rated for zones 4–8 — a cold floor USDA puts at -30 to -20°F. No Florida county sits inside it, so in open ground this is a grown-under-cover plant here rather than a bed plant — which is a statement about Florida winters, not about atlantic white cedar.

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.

When to Plant Atlantic White Cedar 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
Florida runs as cold as USDA zone 8, and no sourced winter-hardiness floor is on record for atlantic white cedar, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether atlantic white cedar is a permanent planting or a replant-every-spring crop for you turns on your own zone within Florida; check its hardiness range against that before treating it as long-lived ground.
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
Atlantic White Cedar prefers acidic soil (pH 3.5-5.5). Florida's sandy can run on the acidic side, which often aligns well — confirm with a soil test before planting. It will grow across that whole span, but it does best between pH 4 and 5.5 — worth knowing before you decide whether a Florida soil test result is a problem or just a number. Drainage requirement: poorly (saturated >50% of year). A soil-survey lookup (NRCS SSURGO) flags whether your specific site matches. pH range, preferred pH and drainage need: We haven't confirmed this against a published source yet.

What Else to Consider for Atlantic White Cedar 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 atlantic white cedar — is covered on the Florida growing guide.
Where in Florida Atlantic White Cedar Is Zone-Hardy
Atlantic White Cedar is rated for USDA zones 4–8. Every Florida county sits above it. Even Holmes County, the state’s coldest at zone 8b, is milder than the plant’s zone 8 ceiling — the constraint here is winter chill it will not get, not cold it cannot take.
Across those 67 counties Florida’s winter-low ladder runs from zone 8b in Holmes County to zone 10b in Palm Beach County — 2 USDA zones of spread, which is 20°F between the two counties’ average coldest night of the year. None of that range reaches the band atlantic white cedar needs, so here the statewide answer really is the answer.

Is Atlantic White Cedar native to Florida?
Yes — the USDA PLANTS Database (accessed 2026-10-19) records Atlantic White Cedar in Florida, and Kew's Plants of the World Online (WCVP) lists Florida in its native range. Planting it supports the pollinators and wildlife that evolved alongside it.

Common Questions About Growing Atlantic White Cedar in Florida
When can I plant Atlantic White Cedar 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). No sourced winter-hardiness floor is on record for Atlantic White Cedar, so this page does not state whether it overwinters in Florida and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is Atlantic White Cedar grown in across Florida?
Florida spans USDA hardiness zones 8b-12a (USDA ARS PHZM 2023). Atlantic White Cedar carries a range of zones 4-8, 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). Atlantic White Cedar needs 140+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Atlantic White Cedar native to Florida?
Yes — the USDA PLANTS Database (accessed 2026-10-19) records Atlantic White Cedar in Florida, and Kew's Plants of the World Online (WCVP) lists Florida in its native range. Planting it supports the pollinators and wildlife that evolved alongside it.
How should I amend the soil for Atlantic White Cedar in Florida?
Atlantic White Cedar prefers pH 3.5-5.5 and poorly (saturated >50% of year) drainage. We haven't confirmed this against a published source yet. Most Florida soils run mildly acidic to neutral; many sites land near this band naturally, and a soil test plus targeted sulfur or organic amendment closes any gap.
Will Atlantic White Cedar actually grow on my specific land in Florida?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores atlantic white cedar against your address's mapped soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
