Generally — Most Areas
star jasmine (zones 8-10) suits most of Florida (8b-12a) — zones 8-10 are in range, and the rest of the state is the exception.
Your yard isn't the whole zone.
Florida spans zones 8b-12a, 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 Florida
The frost window
Across Florida, the last spring hard freeze (28°F) clears between Jan 25 and Feb 10, and the first fall hard freeze lands between Dec 7 and Dec 18 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 300-day window you can count on — up to 327 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 Florida, 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 ~7743 GDD (from PRISM 1991-2020 climate normals), so Florida'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 Florida
Zone compatibility tells you about winter cold survival — but Florida growers also need to think about:
Sandy soils drain too fast and hold few nutrients — frequent fertilization needed
Humidity drives fungal diseases (powdery mildew, black spot, rust)
Hurricane season (June-November) can destroy plantings
Nematodes are a serious pest in sandy FL soils
What to actually do about these — and the constraints that apply to every Florida grower, not just star jasmine — is covered on the Florida growing guide.
Where in Florida Star Jasmine Is Zone-Hardy
Star Jasmine is rated for USDA zones 8–10. 62 of Florida’s 67 counties fall inside that band. The coldest that does is Holmes County at zone 8b. 5 counties sit above its zone 10 ceiling, where the limit is too little winter chill rather than too much cold. Where you are in Florida decides this one.
Across those 67 counties Florida’s winter-low ladder runs from zone 8b in Holmes County to zone 10b in Palm Beach County — 2 USDA zones of spread, which is 20°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. Holmes County holds its last hard freeze (28°F) until about Feb 20, while Okeechobee County is clear by Jan 18 — 33 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 Florida Fits Best
Even within Florida's zones 8b-12a, 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 Florida's frost window — roughly 320 days, opening after the last 28°F freeze (Jan 25 - Feb 10) and closing at the first (Dec 7 - Dec 18), per NOAA Regional Climate Centers ACIS, 1991-2020.

Common Questions About Growing Star Jasmine in Florida
When can I plant Star Jasmine in Florida?
Florida's last spring hard freeze (28°F) clears between Jan 25 and Feb 10, and the first fall hard freeze lands between Dec 7 and Dec 18 (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 Florida?
Florida spans USDA hardiness zones 8b-12a (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 Florida site have?
A typical Florida site sees ~320 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 Florida?
