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 lavender 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 Lavender Stands in Florida
Lavender is rated for zones 5–8 — a cold floor USDA puts at -20 to -10°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 lavender.

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 Lavender 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.
When to start the seed
Those dates are when lavender goes out, not when it starts. It is sown under cover about 10 weeks ahead, so counting back from Florida's late-side last freeze of Feb 10 is what fixes your sowing date — and a yard that clears frost earlier than the state's late date starts earlier still.
Establishment timing
As a long-lived plant, lavender isn't racing the calendar to a harvest date. Plant it in spring once the last hard-freeze window passes so roots settle in through the full season, or in early fall while the soil still holds summer warmth.
Timing tuned to sub-state frost dates — Holmes County, not the statewide average.
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 lavender 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
Lavender wants 180+ frost-free days; a typical Florida site sees ~320 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Lavender needs ~2500 GDD (base 50°F) to ripen. The state median runs ~7743 GDD (from PRISM 1991-2020 climate normals), so Florida's typical season clears that easily.
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
Lavender likes near-neutral soil (pH 5.8-8.3). 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 6.5 and 7.5 — 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), excessive (dry/moderately dry). If your Florida site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
SSURGO maps about 44.6% of Florida as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Lavender tolerates drought well, so wet feet — not dry spells — is its real risk here — your soil map unit, not the state average, is the real answer.

Before you plant lavender for food
Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before lavender goes in. What follows is Florida’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.
Safe to Grow Here?
What the federal record shows across Florida — and how to grow with it.
We checked the federal record across Florida — 76,189 documented sites across 7 of the 9 source types we track.
The most significant on record: 602 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Florida carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.

Highest-Severity Sites
Know Before You Grow
- •Underground tanks leak petroleum as they age — near a former filling station, test the soil.
- •Near a brownfield, raised beds of imported soil give your food clean ground.
- •On a private well, test for nitrates: above 10 mg/L the water needs treatment before irrigating.

What Else to Consider for Lavender 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
Growing lavender here specifically
Lavender rates to USDA zones 5–8 and takes frost damage on growing tissue around -4°F (FAO ECOCROP), but cold isn't the risk in Florida — wet is: with roughly 44.6% of its soils poorly-drained (SSURGO), soggy ground rots the crown.
Give lavender a raised bed or mounded row with coarse amendment so its crown never sit wet. How to handle it →
What to actually do about these — and the constraints that apply to every Florida grower, not just lavender — is covered on the Florida growing guide.
Timing shifts within Florida
Florida isn't one climate. In Holmes County, the last hard freeze (28°F) holds until about Feb 20 — roughly 16 days later than the recorded state median — so plant lavender to your county's window, not the statewide date.
Lavender needs about 180 days of frost-free season to complete its cycle. Even Holmes County — Florida’s shortest season at 281 frost-free days — clears that by 101 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 lavender about 140 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"). Lavender's 180-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Lavender draws honeybees, native bees, and butterflies (high value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, lavender 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. Deer pressure is meaningful across much of Florida; lavender is listed as deer-resistant (USDA PLANTS Database), which makes it a safer pick for unfenced sites. Our deer & wildlife guide carries the full deer-resistant list and how to protect the rest.
Good to Know Before You Plant Lavender
Lavender is listed as toxic to dogs, cats (all) at a mild level (ASPCA). Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear. Worth knowing for placement: lavender overwinters through Florida — its sourced hardiness floor is zone 5 and the state runs no colder than zone 8 — so it stands in the bed year-round, and where you site it is a long-term decision.
Recommended Lavender Varieties for Florida
Florida publishes no state variety trial for lavender, so we won't invent a "best for Florida" list. Choose types rated to your USDA hardiness zone (8b-12a), and confirm winter survival and drainage against your own parcel.
Florida Cooperative Extension
For Florida-specific cultivar recommendations, planting calendars, and pest pressure for lavender, the canonical source is UF/IFAS Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Lavender native to Florida?
No — the USDA PLANTS Database lists Lavender 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 Lavender in Florida
When can I plant Lavender 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). Lavender is a long-lived planting, so target spring just after your local last hard freeze — or early fall while the soil holds warmth — and let it establish through the season.
What hardiness zone is Lavender grown in across Florida?
Florida spans USDA hardiness zones 8b-12a (USDA ARS PHZM 2023). Lavender carries a range of zones 5-8, 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). Lavender needs 180+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Holmes, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Lavender native to Florida?
No — the USDA PLANTS Database lists Lavender 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 Lavender in Florida?
Lavender prefers pH 5.8-8.3 and well (dry spells), excessive (dry/moderately dry) drainage (FAO ECOCROP). 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.
