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.
Your yard isn't the whole zone.
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.

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: 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 atlantic white cedar 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
Atlantic White Cedar wants 140+ frost-free days; a typical Florida site sees ~320 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
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
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.

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.
Timing shifts within Florida
Atlantic White Cedar needs about 140 days of frost-free season to complete its cycle. Even Holmes County — Florida’s shortest season at 281 frost-free days — clears that by 141 days, so season length isn’t the constraint anywhere in Florida. What varies is your own parcel.
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 atlantic white cedar about 180 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"). Atlantic White Cedar's 140-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Florida Cooperative Extension
For Florida-specific cultivar recommendations, planting calendars, and pest pressure for atlantic white cedar, the canonical source is UF/IFAS Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Atlantic White Cedar native to Florida?
Yes — the USDA PLANTS Database (accessed 2026-07-01) documents Atlantic White Cedar as native to Florida. 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 2026-07-01) documents Atlantic White Cedar as native to Florida. 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 (Growable Ground Plant Database). 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?
