Generally — Most Areas
annual scabiosa (zones 4-11) suits most of Florida (8b-12a) — zones 8-11 are in range, and the rest of the state is the exception.
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 annual scabiosa against your land's actual soil, sun, and frost.

When to Plant Annual Scabiosa 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.
Days to maturity vs. the window
At 85 days to maturity (USDA PLANTS Database), counting from the last hard freeze it ripens with 215 days to spare even in Florida's tightest freeze scenario — room for a later start or a second sowing.
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.
Growing Season Fit
The zone check says annual scabiosa survives winter in part of Florida, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Days to maturity
Annual Scabiosa matures in ~85 days (Growable Ground Plant Database). A typical Florida site has ~320 frost-free days, so plenty of room for a second succession.
Growing degree days
Annual Scabiosa needs ~1200 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.

What Else to Consider for Annual Scabiosa 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 annual scabiosa — is covered on the Florida growing guide.
Timing shifts within Florida
Annual Scabiosa needs about 85 days of frost-free season from planting to harvest. Even Holmes County — Florida’s shortest season at 281 frost-free days — clears that by 196 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 annual scabiosa about 235 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"). Annual Scabiosa's 85-day requirement: USDA PLANTS / Growable Ground plant database (days to maturity). A parcel report resolves your address's own frost dates.
Where in Florida Fits Best
Even within Florida's zones 8b-12a, county microclimates differ enough to change what thrives. These counties carry the closest zone match for annual scabiosa (USDA PHZM 2023):
Pollinator + Wildlife Value
Annual Scabiosa 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, annual scabiosa 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.
Florida Cooperative Extension
For Florida-specific cultivar recommendations, planting calendars, and pest pressure for annual scabiosa, the canonical source is UF/IFAS Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Common Questions About Growing Annual Scabiosa in Florida
When can I plant Annual Scabiosa 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.
Can Annual Scabiosa mature before first frost in Florida?
Yes — Annual Scabiosa matures in 85 days (USDA PLANTS Database), and Florida's dependable hard-freeze-free window runs 300 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 215 days of margin. Plant once the last hard freeze has passed — two to three weeks later for anything tender — and it ripens ahead of the first fall freeze.
What hardiness zone is Annual Scabiosa grown in across Florida?
Florida spans USDA hardiness zones 8b-12a (USDA ARS PHZM 2023). Annual Scabiosa carries a range of zones 4-11, 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). Annual Scabiosa 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 Annual Scabiosa actually grow on my specific land in Florida?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores annual scabiosa against your address's exact soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
