Generally — Most Areas
star jasmine (zones 8-10) suits most of North Carolina (6a-9a) — zones 8-9 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
North Carolina spans zones 6a-9a, 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.

When to Plant Star Jasmine in North Carolina
The frost window
Across North Carolina, the last spring hard freeze (28°F) clears between Mar 11 and Mar 24, and the first fall hard freeze lands between Nov 10 and Nov 25 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 231-day window you can count on — up to 259 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 North 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 ~4537 GDD (from PRISM 1991-2020 climate normals), so North 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 North Carolina
Zone compatibility tells you about winter cold survival — but North Carolina growers also need to think about:
Red Piedmont clay is hard to work and drains poorly
Humidity drives significant disease pressure
Hurricane risk on the coastal plain
What to actually do about these — and the constraints that apply to every North Carolina grower, not just star jasmine — is covered on the North Carolina growing guide.
Where in North Carolina Star Jasmine Is Zone-Hardy
Star Jasmine is rated for USDA zones 8–10. 69 of North Carolina’s 100 counties fall inside that band. The coldest that does is Alamance County at zone 8a. 31 counties sit below the plant’s zone 8 floor, where an unprotected plant is relying on snow cover and a mild year. Where you are in North Carolina decides this one.
Across those 100 counties North Carolina’s winter-low ladder runs from zone 6b in Avery County to zone 9a in Dare County — 2.5 USDA zones of spread, which is 25°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. Swain County holds its last hard freeze (28°F) until about Apr 27, while Dare County is clear by Feb 18 — 68 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 North Carolina Fits Best
Even within North Carolina's zones 6a-9a, 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 North Carolina's frost window — roughly 245 days, opening after the last 28°F freeze (Mar 11 - Mar 24) and closing at the first (Nov 10 - Nov 25), per NOAA Regional Climate Centers ACIS, 1991-2020.

Common Questions About Growing Star Jasmine in North Carolina
When can I plant Star Jasmine in North Carolina?
North Carolina's last spring hard freeze (28°F) clears between Mar 11 and Mar 24, and the first fall hard freeze lands between Nov 10 and Nov 25 (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 North Carolina?
North Carolina spans USDA hardiness zones 6a-9a (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 North Carolina site have?
A typical North Carolina site sees ~245 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 North Carolina?
