Conditional — Some Areas
tea olive (zones 9-11) 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 tea olive against your parcel's actual hardiness, soil, and sun.

When to Plant Tea Olive 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 tea olive, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether tea olive 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 tea olive survives winter in part of Alabama, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Tea Olive wants 250+ frost-free days; a typical Alabama site sees ~266 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a tight window — use transplants and pick early-maturing cultivars.
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
Tea Olive likes near-neutral soil (pH 5.5-7.5). That's the common-ground band across Alabama's red clay and sandy loam — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 6 and 7 — worth knowing before you decide whether a Alabama soil test result is a problem or just a number. 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 Tea Olive 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 tea olive — is covered on the Alabama growing guide.
Timing shifts within Alabama
Tea Olive needs about 250 days of frost-free season to complete its cycle. 45 of Alabama’s 67 counties give it that outright. The tightest that does is Bibb County at 250 frost-free days — 0 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
Across Alabama’s 67 counties the frost-free season runs from 225 days in Marion County to 297 days in Mobile County — a spread of 72 days, which is why a single statewide planting date misleads. The median Alabama county sees 266 frost-free days, leaving tea olive about 16 days of slack on a typical parcel — room for a second sowing where the season runs long.
County last-freeze dates and frost-free day counts: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). Tea Olive's 250-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
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 tea olive (USDA PHZM 2023):
Pollinator + Wildlife Value
Tea Olive draws honeybees and butterflies (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, tea olive 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 tea olive, the canonical source is Alabama Cooperative Extension System. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Tea Olive native to Alabama?
No — the USDA PLANTS Database lists Tea Olive 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 Tea Olive in Alabama
When can I plant Tea Olive 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 Tea Olive, 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 Tea Olive grown in across Alabama?
Alabama spans USDA hardiness zones 7b-9b (USDA ARS PHZM 2023). Tea Olive carries a range of zones 9-11, 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). Tea Olive needs 250+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Tea Olive native to Alabama?
No — the USDA PLANTS Database lists Tea Olive 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.
How should I amend the soil for Tea Olive in Alabama?
Tea Olive prefers pH 5.5-7.5 and well (dry spells) drainage (Growable Ground Plant Database). That sits in the common-ground band across Alabama soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
Will Tea Olive actually grow on my specific land in Alabama?
