Conditional — Some Areas
calathea (zones 11-12) reaches only part of Florida (8b-12a): zones 11-12 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 calathea against your parcel's actual hardiness, soil, and sun.

When to Plant Calathea 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 calathea, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether calathea 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.
Soil + Drainage Fit
Calathea likes near-neutral soil (pH 5.5-7). 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 6 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.

What Else to Consider for Calathea 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 calathea — is covered on the Florida growing guide.
Where in Florida Calathea Is Zone-Hardy
Calathea is rated for USDA zones 11–12. No Florida county reaches it. Even Palm Beach County, the state’s mildest winter at zone 10b, sits below the plant’s zone 11 floor — so in open ground this one needs winter protection here, or a container that comes under cover.
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 calathea needs, so here the statewide answer really is the answer.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. Calathea’s zone 11–12 band: USDA PLANTS / Growable Ground plant database. A parcel report resolves your address’s own zone and frost dates rather than its county’s.
Florida Cooperative Extension
For Florida-specific cultivar recommendations, planting calendars, and pest pressure for calathea, the canonical source is UF/IFAS Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Calathea native to Florida?
No — the USDA PLANTS Database lists Calathea 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 Calathea in Florida
When can I plant Calathea 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 Calathea, 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 Calathea grown in across Florida?
Florida spans USDA hardiness zones 8b-12a (USDA ARS PHZM 2023). Calathea carries a range of zones 11-12, 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). Calathea 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 Calathea native to Florida?
No — the USDA PLANTS Database lists Calathea 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 Calathea in Florida?
Calathea prefers pH 5.5-7 and well (dry spells) drainage (Growable Ground Plant Database). 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 Calathea actually grow on my specific land in Florida?
