Zones Fit — Chill Unconfirmed
Hardiness allows Kentucky coffeetree here — the zones overlap. Winter chill is the harder question, and our chill-hour figure for this plant is not corroborated against a published source, so we do not publish a verdict on it. The chill line below shows what Florida typically banks; treat it as a starting point and confirm with a local Extension office.

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 kentucky coffeetree 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.
Measured across 67 Florida counties. USDA PHZM 2023, per county. Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where in Florida Fits Best
Kentucky Coffeetree is rated for zones 4–10 — a cold floor USDA puts at -30 to -20°F. Against Florida’s 67 counties that band holds in 62 of them, and the line runs at Holmes County (zone 8b), the coldest county still inside it.

Too little winter chill rather than too much cold — a low-chill selection is what changes 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 kentucky coffeetree (USDA PHZM 2023):

When to Plant Kentucky Coffeetree 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 kentucky coffeetree, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether kentucky coffeetree 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.
Growing Season Fit
The zone check says kentucky coffeetree survives winter in part of Florida, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Chill hours
Kentucky Coffeetree requires ~500 chill hours (32-45°F dormancy window). Florida typically banks ~0 chill hours per winter, short of this plant's requirement — fruit set may suffer in mild years without a low-chill cultivar.
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
Kentucky Coffeetree likes near-neutral soil (pH 6-8). That's the common-ground band across Florida's sandy and muck (everglades) — a soil test confirms it for your site.
Plant pH requirements: FAO ECOCROP and USDA PLANTS, with the remaining rows from other published sources or Growable Ground compilation. 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.
What Else to Consider for Kentucky Coffeetree 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 kentucky coffeetree — is covered on the Florida growing guide.
Where in Florida Kentucky Coffeetree Is Zone-Hardy
Kentucky Coffeetree is rated for USDA zones 4–10. 62 of Florida’s 67 counties fall inside that band. The coldest that does is Holmes County at zone 8b. 5 counties sit above its zone 10 ceiling, where the limit is too little winter chill rather than too much cold. Where you are in Florida decides this one.
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. That is why a statewide hardiness answer is where you start and not where you finish.
The planting window moves with it. Holmes County holds its last hard freeze (28°F) until about Feb 20, while Okeechobee County is clear by Jan 18 — 33 days apart. Set kentucky coffeetree out on your county’s date, not the state’s.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F killing freeze — earlier than the folk 32°F "last frost".

Is Kentucky Coffeetree native to Florida?
Kentucky Coffeetree is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Florida. It can still earn a place in a Florida garden — the zone comparison above tells you whether it will thrive.

Common Questions About Growing Kentucky Coffeetree in Florida
When can I plant Kentucky Coffeetree 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 Kentucky Coffeetree, 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 Kentucky Coffeetree grown in across Florida?
Florida spans USDA hardiness zones 8b-12a (USDA ARS PHZM 2023). Kentucky Coffeetree carries a range of zones 4-10, 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). Kentucky Coffeetree should be matched against that window, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Kentucky Coffeetree native to Florida?
Kentucky Coffeetree is native to parts of the Lower 48, but the USDA PLANTS Database (accessed 2026-07-01) does not document a native range in Florida. It can still earn a place in a Florida garden — the zone comparison above tells you whether it will thrive.
How should I amend the soil for Kentucky Coffeetree in Florida?
Kentucky Coffeetree prefers pH 6-8 (USDA PLANTS). 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.
Will Kentucky Coffeetree actually grow on my specific land in Florida?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores kentucky coffeetree against your address's exact soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
