Conditional — Some Areas
French tarragon (zones 3-7) reaches only part of South Carolina (7a-9b): zone 7 are in range, so where you are in the state decides it.
Your yard isn't the whole zone.
South Carolina 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 french tarragon against your land's actual soil, sun, and frost.

When to Plant French Tarragon in South Carolina
The frost window
Across South Carolina, the last spring hard freeze (28°F) clears between Feb 27 and Mar 12, and the first fall hard freeze lands between Nov 23 and Dec 1 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 256-day window you can count on — up to 277 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.
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.

What Else to Consider for French Tarragon in South Carolina
Zone compatibility tells you about winter cold survival — but South Carolina growers also need to think about:
Red Piedmont clay requires amendment for drainage
High heat and humidity promote diseases
Hurricane risk along the coast
What to actually do about these — and the constraints that apply to every South Carolina grower, not just french tarragon — is covered on the South Carolina growing guide.
Where in South Carolina French Tarragon Is Zone-Hardy
French Tarragon is rated for USDA zones 3–7. Every South Carolina county sits above it. Even Abbeville County, the state’s coldest at zone 8a, is milder than the plant’s zone 7 ceiling — the constraint here is winter chill it will not get, not cold it cannot take.
Across those 46 counties South Carolina’s winter-low ladder runs from zone 8a in Abbeville County to zone 9a in Jasper County — 1 USDA zone of spread, which is 10°F between the two counties’ average coldest night of the year. None of that range reaches the band french tarragon needs, so here the statewide answer really is the answer.

Common Questions About Growing French Tarragon in South Carolina
When can I plant French Tarragon in South Carolina?
South Carolina's last spring hard freeze (28°F) clears between Feb 27 and Mar 12, and the first fall hard freeze lands between Nov 23 and Dec 1 (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.
What hardiness zone is French Tarragon grown in across South Carolina?
South Carolina spans USDA hardiness zones 7a-9b (USDA ARS PHZM 2023). French Tarragon carries a range of zones 3-7, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical South Carolina site have?
A typical South Carolina site sees ~265 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). French Tarragon 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 French Tarragon actually grow on my specific land in South Carolina?
