Generally — Most Areas
star jasmine (zones 8-10) suits most of South Carolina (7a-9b) — zones 8-9 are in range, and the rest of the state is the exception.
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 star jasmine against your land's actual soil, sun, and frost.
We read public map data for this spot — soil, climate, flood, and parcel records. How we handle your address.

When to Plant Star Jasmine 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.
Growing Season Fit
The zone check says star jasmine survives winter in part of South Carolina, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Growing degree days
Star Jasmine needs ~1200 GDD (base 50°F) to ripen. The state median runs ~5233 GDD (from PRISM 1991-2020 climate normals), so South Carolina'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 Star Jasmine 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 star jasmine — is covered on the South Carolina growing guide.
Where in South Carolina Star Jasmine Is Zone-Hardy
Star Jasmine is rated for USDA zones 8–10. Every one of South Carolina’s 46 counties sits inside that band — from Abbeville County at zone 8a to Jasper County at zone 9a — so winter cold is not what decides this plant anywhere in the state. What is left to vary is your own parcel: slope, shelter and cold-air drainage routinely move a site half a zone either way from the county figure.
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. That is why a statewide hardiness answer is where you start and not where you finish.
The planting window moves with it. Chester County holds its last hard freeze (28°F) until about Mar 22, while Charleston County is clear by Feb 1 — 49 days apart. Set star jasmine out on your county’s date, not the state’s.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F killing freeze — earlier than the folk 32°F "last frost". Star Jasmine’s zone 8–10 band: USDA PLANTS / Growable Ground plant database. A parcel report resolves your address’s own zone and frost dates rather than its county’s.
Where in South Carolina Fits Best
Even within South Carolina's zones 7a-9b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for star jasmine (USDA PHZM 2023):
Pollinator + Wildlife Value
Star Jasmine draws honeybees and butterflies (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, star jasmine can only work that bloom inside South Carolina's frost window — roughly 265 days, opening after the last 28°F freeze (Feb 27 - Mar 12) and closing at the first (Nov 23 - Dec 1), per NOAA Regional Climate Centers ACIS, 1991-2020.

Common Questions About Growing Star Jasmine in South Carolina
When can I plant Star Jasmine 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 Star Jasmine grown in across South Carolina?
South Carolina spans USDA hardiness zones 7a-9b (USDA ARS PHZM 2023). Star Jasmine carries a range of zones 8-10, 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). Star Jasmine 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 Star Jasmine actually grow on my specific land in South Carolina?
