Yes — Strong Match
annual scabiosa (zones 4-11) covers every zone Georgia contains (7a-9b), so hardiness is not what limits it anywhere in the state.
Your yard isn't the whole zone.
Georgia spans zones 7a-9b, 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 Georgia
The frost window
Across Georgia, the last spring hard freeze (28°F) clears between Feb 17 and Mar 10, and the first fall hard freeze lands between Nov 24 and Dec 4 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 259-day window you can count on — up to 290 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 174 days to spare even in Georgia'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 here. 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 Georgia site has ~275 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 ~5616 GDD (from PRISM 1991-2020 climate normals), so Georgia'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 Georgia
Zone compatibility tells you about winter cold survival — but Georgia growers also need to think about:
Heavy red Piedmont clay is difficult to work and drains poorly
High humidity drives fungal diseases in summer
Fire ants are a persistent pest in gardens across the state
Summer heat (90-100F) can stress cool-season crops by May
What to actually do about these — and the constraints that apply to every Georgia grower, not just annual scabiosa — is covered on the Georgia growing guide.
Timing shifts within Georgia
Annual Scabiosa needs about 85 days of frost-free season from planting to harvest. Even Towns County — Georgia’s shortest season at 204 frost-free days — clears that by 119 days, so season length isn’t the constraint anywhere in Georgia. What varies is your own parcel.
Across Georgia’s 159 counties the frost-free season runs from 204 days in Towns County to 305 days in Colquitt County — a spread of 101 days, which is why a single statewide planting date misleads. The median Georgia county sees 275 frost-free days, leaving annual scabiosa about 190 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 Georgia Fits Best
Even within Georgia's zones 7a-9b, 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 Georgia's frost window — roughly 275 days, opening after the last 28°F freeze (Feb 17 - Mar 10) and closing at the first (Nov 24 - Dec 4), per NOAA Regional Climate Centers ACIS, 1991-2020.

Common Questions About Growing Annual Scabiosa in Georgia
When can I plant Annual Scabiosa in Georgia?
Georgia's last spring hard freeze (28°F) clears between Feb 17 and Mar 10, and the first fall hard freeze lands between Nov 24 and Dec 4 (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 Georgia?
Yes — Annual Scabiosa matures in 85 days (USDA PLANTS Database), and Georgia's dependable hard-freeze-free window runs 259 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 174 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 Georgia?
Georgia spans USDA hardiness zones 7a-9b (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 Georgia site have?
A typical Georgia site sees ~275 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 Georgia?
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.
