State guide
Planting zones in Florida
Florida spans USDA zones 8b to 11b across its 1,008 ZIP codes, so there is no single zone for the state and anyone who gives you one is rounding. 28% of its ZIP codes are zone 10a; the rest are not.
Your ZIP code
Get the exact answer for your address
Everything above describes Florida as a whole. Hardiness zones and freeze dates are published per ZIP code, so yours is exact — enter it and this page will tell you your zone, which NOAA station it comes from and how far away that station is.
Which zone you are in depends where you are
Florida covers 7 hardiness zones. A guide that gives the state one zone has picked whichever is largest and rounded everyone else into it — which is fine for the 28% in zone 10a and wrong for the other 72%. Here is the actual split, by ZIP code.
| Zone | ZIP codes | Share | |
|---|---|---|---|
| 10a | 282 | 28% | |
| 9b | 238 | 24% | |
| 9a | 213 | 21% | |
| 10b | 158 | 16% | |
| 11a | 101 | 10% | |
| 8b | 8 | 1% | |
| 11b | 8 | 1% |
Zones are published per ZIP code, so yours is exact even though the state's is not. The hardiness tool will tell you which one you are in.
Your freeze dates
No freeze range is given for Florida, and that is the honest answer rather than a missing one. Of its 176 NOAA stations, only 56 have an ordinary freeze window. 37 record no freeze at any probability. 83 sit where the freeze window crosses New Year. A range across the remainder would be a claim about Florida built from the small minority of it that behaves like somewhere else.
Frost is simply not the constraint across most of Florida. The tools below still answer for individual ZIP codes, and will say which case yours falls in.
Your growing season
NOAA publishes a growing-season length for each station, and across the 176 stations in Florida it runs 237–365 days . That figure is published, not computed from the two freeze dates — subtracting one from the other gives the wrong answer wherever a season crosses New Year. Mean summer high (June–August) runs 87–94 °F , reaching the 90 °F point where cool-season crops bolt and tomato and pepper pollen fails — so midsummer sowings of lettuce and its relatives are worth holding in the hotter parts of the state.
The ends of each range, named
A range with no station behind it cannot be checked, and Florida has too many stations to table them all. So every figure above is reported here with the station standing at each end of it, by name and NOAA ID. No station on this page represents Florida — these are its edges, which is a different claim.
| Measure | Earliest / lowest | Station | Latest / highest | Station |
|---|---|---|---|---|
| Growing season | 237 days | Crestview Bob Sikes AP, FL USW00013884 | 365 days | Everglades City 5 NE, FL USW00092826 |
| Mean summer high | 87 °F | Palm Coast 6Ne, FL USC00086767 | 94 °F | Punta Gorda 4 Ese, FL USC00087397 |
These are medians, not averages — NOAA publishes freeze dates as a probability distribution, and half of years freeze later than the date shown.
What survives the winter changes across Florida
Of 74 perennial fruits, nuts, berries, vegetables and herbs, 54 come through the winter in zone 8b and only 18 in zone 11a. Winter hardiness runs on the zone alone, so each row below is exact for the ZIP codes in it.
| Zone | ZIPs | Survive | Fail for being too warm |
|---|---|---|---|
| 8b | 8 | 54 of 74 | 11 |
| 9a | 213 | 46 of 74 | 25 |
| 9b | 238 | 40 of 74 | 32 |
| 10a | 282 | 25 of 74 | 49 |
| 10b | 158 | 24 of 74 | 50 |
| 11a | 101 | 18 of 74 | 56 |
| 11b | 8 | 18 of 74 | 56 |
The best zone in Florida is 8b, which is not its mildest — 11b is. The count peaks in the middle and falls both ways, because the warm end loses plants to insufficient winter chill and summer heat rather than to cold. Most temperate fruit needs a documented number of hours below about 45 °F to break dormancy and set a crop, so an apple fails in a winter that is too warm; currants and rhubarb cook in the heat that comes with it.

Your own ZIP
Work out your own dates
Each of these takes a ZIP code and answers for that ZIP alone, citing the station it used and how far away it is. There is a ZIP box in the header of every page.
- What survives my winter?
Runs on the hardiness zone, so it answers exactly for your ZIP code rather than for Florida as a whole — 74 perennial fruits, berries, vegetables and herbs.
- When do I start my seeds?
Dates every spring job from your own last freeze — sow indoors, set out, direct sow.
- When do I sow the next round?
How often each crop is worth re-sowing, and when the next sowing is due.
- What can I still plant?
Counts the growing days left before your first fall freeze, crop by crop.

Each link opens an Amazon search rather than a product we picked. We have not tested these and do not rank them — the search is the honest version, and you choose.
- Shade clothSummer highs here average 91 °F, at or above the 90 °F point where lettuce and spinach bolt and tomato pollen fails.
- Soaker hose and drip kitsThe stations here publish no ordinary freeze window, so frost is not what limits the season — water is, through a summer that does not stop.

Where these numbers come from
The hardiness zone is the USDA 2023 Plant Hardiness Zone Map, published per ZIP code by PRISM at Oregon State. The freeze dates, growing seasons and summer highs are NOAA's 1991–2020 Climate Normals, read from every station in Florida. Which ZIP codes are in Florida comes from the Census ZIP-to-county relation, since a county's federal code begins with its state's. Nothing here is estimated.
This page names no single station for Florida on purpose. Picking one to represent a state sounds reasonable and is not — the same reason the metro pages refuse it, only more so at this size. Instead every range names the station at each end, so you can check both without either one being made to speak for the state.
