Conditional — Some Areas
star jasmine (zones 8-10) reaches only part of Arkansas (6b-8b): zone 8 are in range, so where you are in the state decides it.
Your yard isn't the whole zone.
Arkansas spans zones 6b-8b, 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 Arkansas
The frost window
Across Arkansas, the last spring hard freeze (28°F) clears between Mar 2 and Mar 20, and the first fall hard freeze lands between Nov 15 and Nov 23 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 240-day window you can count on — up to 266 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 Arkansas, 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 ~4819 GDD (from PRISM 1991-2020 climate normals), so Arkansas'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 Arkansas
Zone compatibility tells you about winter cold survival — but Arkansas growers also need to think about:
Hot, humid summers drive fungal and bacterial diseases
Heavy clay soils in parts of the Ozarks
Severe spring storms and hail risk
What to actually do about these — and the constraints that apply to every Arkansas grower, not just star jasmine — is covered on the Arkansas growing guide.
Where in Arkansas Star Jasmine Is Zone-Hardy
Star Jasmine is rated for USDA zones 8–10. 53 of Arkansas’s 75 counties fall inside that band. The coldest that does is Calhoun County at zone 8a. 22 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 Arkansas decides this one.
Across those 75 counties Arkansas’s winter-low ladder runs from zone 7a in Benton County to zone 8b in Union County — 1.5 USDA zones of spread, which is 15°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. Carroll County holds its last hard freeze (28°F) until about Mar 26, while Chicot County is clear by Feb 19 — 35 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 Arkansas Fits Best
Even within Arkansas's zones 6b-8b, 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 Arkansas's frost window — roughly 254 days, opening after the last 28°F freeze (Mar 2 - Mar 20) and closing at the first (Nov 15 - Nov 23), per NOAA Regional Climate Centers ACIS, 1991-2020.

Common Questions About Growing Star Jasmine in Arkansas
When can I plant Star Jasmine in Arkansas?
Arkansas's last spring hard freeze (28°F) clears between Mar 2 and Mar 20, and the first fall hard freeze lands between Nov 15 and Nov 23 (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 Arkansas?
Arkansas spans USDA hardiness zones 6b-8b (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 Arkansas site have?
A typical Arkansas site sees ~254 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 Arkansas?
