Unlikely — Zone Mismatch
tamalini (zones 11-13) does not overlap with Georgia's zone range (7a-9b). Growing outdoors is unlikely without significant protection.
2 zones short — what would close it
Tamalini is hardy to zone 11, and the warmest ground in Georgia is zone 9 — 2 zones short. Planted in open ground it will not survive a Georgia winter. To grow it here, grow tamalini under glass — a greenhouse is the only lift this wide the engine models.

When to Plant Tamalini in Georgia
The frost window
Across Georgia, the last spring hard freeze (28°F) clears between Feb 17 and Mar 10, and the first fall hard freeze lands between Nov 24 and Dec 4 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 259-day window you can count on — up to 290 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
Georgia runs as cold as USDA zone 7, and no sourced winter-hardiness floor is on record for tamalini, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether tamalini is a permanent planting or a replant-every-spring crop for you turns on your own zone within Georgia; check its hardiness range against that before treating it as long-lived ground.
Timing tuned to sub-state frost dates — Towns County, not the statewide average.
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 tamalini does not survive a Georgia winter in the ground. The season figures below measure a different question — whether it could finish a season here at all — and they only bear on Georgia under protection.
Frost-free days
Tamalini wants 210+ frost-free days; a typical Georgia site sees ~275 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
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
Tamalini likes near-neutral soil (pH 5-7.5). That's the common-ground band across Georgia's red clay (piedmont) and sandy loam (coastal plain) — a soil test confirms it for your site. It will grow across that whole span, but it does best between pH 5.5 and 6.5 — worth knowing before you decide whether a Georgia soil test result is a problem or just a number. Drainage matters: this plant wants poorly (saturated >50% of year), well (dry spells). If your Georgia site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.
Your land, not the state average
SSURGO maps about 20.4% of Georgia as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Tamalini sits mid-range for drought tolerance, so either extreme can cost you — your soil map unit, not the state average, is the real answer.

Tamalini in Georgia — Quick Answer
- Verdict: Unlikely — Zone Mismatch
- Plant Zones: 11-13 (USDA PLANTS Database)
- State Zones: 7a-9b (USDA ARS PHZM 2023)
- Growing Season: 28°F hard freezes about Feb 17 - Mar 10 to Nov 24 - Dec 4 (NOAA Regional Climate Centers ACIS, 1991-2020)
What Else to Consider for Tamalini in Georgia
Zone compatibility tells you about winter cold survival — but Georgia growers also need to think about:
Heavy red Piedmont clay is difficult to work and drains poorly
High humidity drives fungal diseases in summer
Fire ants are a persistent pest in gardens across the state
Summer heat (90-100F) can stress cool-season crops by May
Growing tamalini here specifically
Tamalini rates to USDA zones 11–13 and is hardy to about 39°F, but cold isn't the risk in Georgia — wet is: with roughly 20.4% of its soils poorly-drained (SSURGO), soggy ground rots the crown.
Give tamalini a raised bed or mounded row with coarse amendment so its crown never sit wet. How to handle it →
What to actually do about these — and the constraints that apply to every Georgia grower, not just tamalini — is covered on the Georgia growing guide.
Timing shifts within Georgia
Georgia isn't one climate. In Towns County, the last hard freeze (28°F) holds until about Apr 7 — roughly 39 days later than the recorded state median — so plant tamalini to your county's window, not the statewide date.
Tamalini needs about 210 days of frost-free season to complete its cycle. 157 of Georgia’s 159 counties give it that outright. The tightest that does is Fannin County at 219 frost-free days — 9 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
Across Georgia’s 159 counties the frost-free season runs from 204 days in Towns County to 305 days in Colquitt County — a spread of 101 days, which is why a single statewide planting date misleads. The median Georgia county sees 275 frost-free days, leaving tamalini about 65 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"). Tamalini's 210-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Pollinator + Wildlife Value
Tamalini draws honeybees, native bees, and butterflies (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, tamalini can only work that bloom inside Georgia's frost window — roughly 275 days, opening after the last 28°F freeze (Feb 17 - Mar 10) and closing at the first (Nov 24 - Dec 4), per NOAA Regional Climate Centers ACIS, 1991-2020.
Good to Know Before You Plant Tamalini
Tamalini is listed as toxic to dogs, cats (seeds, pods) at a mild level (Pet Poison Helpline). Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear.

Common Questions About Growing Tamalini in Georgia
When can I plant Tamalini in Georgia?
Georgia's last spring hard freeze (28°F) clears between Feb 17 and Mar 10, and the first fall hard freeze lands between Nov 24 and Dec 4 (NOAA Regional Climate Centers ACIS, 1991-2020). No sourced winter-hardiness floor is on record for Tamalini, so this page does not state whether it overwinters in Georgia 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 Tamalini grown in across Georgia?
Georgia spans USDA hardiness zones 7a-9b (USDA ARS PHZM 2023). Tamalini carries a range of zones 11-13, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Georgia site have?
A typical Georgia site sees ~275 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Tamalini needs 210+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date. In cooler counties like Towns, the freeze-free season runs shorter than the state average, so verify your own county's window.
How should I amend the soil for Tamalini in Georgia?
Tamalini prefers pH 5-7.5 and poorly (saturated >50% of year), well (dry spells) drainage (FAO ECOCROP). That sits in the common-ground band across Georgia soils — a 30-minute soil test from a local Extension lab confirms it for your specific site.
