Conditional — Some Areas
tree peony (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 has its own microclimate — slope, trees, and low spots shift frost and sun across a single parcel. Enter your address and we'll score tree peony against your land's actual soil, sun, and frost.

Florida is not one climate
A single Florida answer averages 67 counties whose growing seasons are 84 days apart — from 281 frost-free days in Holmes County to 365 in Sarasota County. Which end of that your land sits nearer changes what tree peony can finish before the first hard freeze.
The middle half of 67 counties runs 300–333 days, with a median of 320 days — a 84-day span end to end.

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 Tree Peony Stands in Florida
Tree Peony 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 tree peony.

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.

When to Plant Tree Peony 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.
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.
What Else to Consider for Tree Peony 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 tree peony — is covered on the Florida growing guide.
Where in Florida Tree Peony Is Zone-Hardy
Tree Peony 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 tree peony needs, so here the statewide answer really is the answer.

Pollinator + Wildlife Value
Tree Peony draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, tree peony 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.

Common Questions About Growing Tree Peony in Florida
When can I plant Tree Peony 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). Time outdoor planting to after the last hard freeze for your specific site — a further two to three weeks for anything tender — and count back from those dates for transplant scheduling.
What hardiness zone is Tree Peony grown in across Florida?
Florida spans USDA hardiness zones 8b-12a (USDA ARS PHZM 2023). Tree Peony 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). Tree Peony 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.
Will Tree Peony actually grow on my specific land in Florida?
