Conditional — Some Areas
pittosporum (zones 9-10) reaches only part of Alabama (7b-9b): zone 9 are in range, so where you are in the state decides it.
Your yard isn't the whole zone.
Alabama spans zones 7b-9b, but your yard sits in exactly one — and slope, tree cover, and cold-air pockets nudge it further. Enter your address and we'll score pittosporum against your parcel's actual hardiness, soil, and sun.

When to Plant Pittosporum in Alabama
The frost window
Across Alabama, the last spring hard freeze (28°F) clears between Feb 24 and Mar 16, and the first fall hard freeze lands between Nov 15 and Nov 28 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 244-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.
Winter standing
Alabama runs as cold as USDA zone 7, and no sourced winter-hardiness floor is on record for pittosporum, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether pittosporum is a permanent planting or a replant-every-spring crop for you turns on your own zone within Alabama; check its hardiness range against that before treating it as long-lived ground.
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 pittosporum survives winter in part of Alabama, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Chill hours
Pittosporum requires ~100 chill hours (32-45°F dormancy window). Alabama typically banks ~1226 chill hours per winter (from PRISM 1991-2020 climate normals), which keeps this plant on track.
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.
Soil + Drainage Fit
Drainage matters: this plant wants well (dry spells). If your Alabama site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

What Else to Consider for Pittosporum in Alabama
Zone compatibility tells you about winter cold survival — but Alabama growers also need to think about:
Heavy clay soils in the Piedmont region
High humidity promotes fungal diseases
Fire ants are a persistent garden pest
What to actually do about these — and the constraints that apply to every Alabama grower, not just pittosporum — is covered on the Alabama growing guide.
Where in Alabama Pittosporum Is Zone-Hardy
Pittosporum is rated for USDA zones 9–10. 3 of Alabama’s 67 counties fall inside that band. The coldest that does is Baldwin County at zone 9a. 64 counties sit below the plant’s zone 9 floor, where an unprotected plant is relying on snow cover and a mild year. Where you are in Alabama decides this one.
Across those 67 counties Alabama’s winter-low ladder runs from zone 7b in Jackson County to zone 9a in Mobile 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. Marion County holds its last hard freeze (28°F) until about Mar 28, while Mobile County is clear by Feb 9 — 47 days apart. Set pittosporum 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". Pittosporum’s zone 9–10 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 Alabama Fits Best
Even within Alabama's zones 7b-9b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for pittosporum (USDA PHZM 2023):
Pollinator + Wildlife Value
Pittosporum draws honeybees (low value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, pittosporum can only work that bloom inside Alabama's frost window — roughly 266 days, opening after the last 28°F freeze (Feb 24 - Mar 16) and closing at the first (Nov 15 - Nov 28), per NOAA Regional Climate Centers ACIS, 1991-2020.
Alabama Cooperative Extension
For Alabama-specific cultivar recommendations, planting calendars, and pest pressure for pittosporum, the canonical source is Alabama Cooperative Extension System. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Pittosporum native to Alabama?
No — the USDA PLANTS Database lists Pittosporum as introduced rather than native in the Lower 48, so it is not part of Alabama's native flora. It grows here as a garden plant; pairing it with a few Alabama natives keeps local pollinators fed too.

Common Questions About Growing Pittosporum in Alabama
When can I plant Pittosporum in Alabama?
Alabama's last spring hard freeze (28°F) clears between Feb 24 and Mar 16, and the first fall hard freeze lands between Nov 15 and Nov 28 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Pittosporum, so this page does not state whether it overwinters in Alabama and publishes no fall establishment date for it — check its hardiness range against your own zone before treating it as a permanent planting.
What hardiness zone is Pittosporum grown in across Alabama?
Alabama spans USDA hardiness zones 7b-9b (USDA ARS PHZM 2023). Pittosporum carries a range of zones 9-10, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Alabama site have?
A typical Alabama site sees ~266 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Pittosporum 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.
Is Pittosporum native to Alabama?
No — the USDA PLANTS Database lists Pittosporum as introduced rather than native in the Lower 48, so it is not part of Alabama's native flora. It grows here as a garden plant; pairing it with a few Alabama natives keeps local pollinators fed too.
Will Pittosporum actually grow on my specific land in Alabama?
