Conditional — Some Areas
Vietnamese coriander (zones 9-11) reaches only part of Georgia (7a-9b): zone 9 are in range, so where you are in the state decides it.
Your yard isn't the whole zone.
Georgia spans zones 7a-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 vietnamese coriander against your parcel's actual hardiness, soil, and sun.

When to Plant Vietnamese Coriander 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.
When to start the seed
Those dates are when vietnamese coriander goes out, not when it starts. It is sown under cover about 6 weeks ahead, so counting back from Georgia's late-side last freeze of Mar 10 is what fixes your sowing date — and a yard that clears frost earlier than the state's late date starts earlier still.
Winter standing
Georgia runs as cold as USDA zone 7, and no sourced winter-hardiness floor is on record for vietnamese coriander, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether vietnamese coriander 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.
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 vietnamese coriander survives winter in part of Georgia, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Vietnamese Coriander wants 120+ frost-free days; a typical Georgia site sees ~275 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Vietnamese Coriander needs ~3000 GDD (base 50°F) to ripen. The state median runs ~5616 GDD (from PRISM 1991-2020 climate normals), so Georgia'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.
Soil + Drainage Fit
Vietnamese Coriander likes near-neutral soil (pH 5.5-7.5). 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 6 and 7 — worth knowing before you decide whether a Georgia soil test result is a problem or just a number. Drainage requirement: poorly (saturated >50% of year). A soil-survey lookup (NRCS SSURGO) flags whether your specific site matches.

What Else to Consider for Vietnamese Coriander 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
What to actually do about these — and the constraints that apply to every Georgia grower, not just vietnamese coriander — is covered on the Georgia growing guide.
Timing shifts within Georgia
Vietnamese Coriander needs about 120 days of frost-free season to complete its cycle. Even Towns County — Georgia’s shortest season at 204 frost-free days — clears that by 84 days, so season length isn’t the constraint anywhere in Georgia. What varies is your own parcel.
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 vietnamese coriander about 155 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"). Vietnamese Coriander's 120-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Where in Georgia Fits Best
Even within Georgia's zones 7a-9b, county microclimates differ enough to change what thrives. These counties carry the closest zone match for vietnamese coriander (USDA PHZM 2023):
Pollinator + Wildlife Value
Vietnamese Coriander draws honeybees (low value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, vietnamese coriander 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.
Georgia Cooperative Extension
For Georgia-specific cultivar recommendations, planting calendars, and pest pressure for vietnamese coriander, the canonical source is UGA Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Vietnamese Coriander native to Georgia?
No — the USDA PLANTS Database lists Vietnamese Coriander as introduced rather than native in the Lower 48, so it is not part of Georgia's native flora. It grows here as a garden plant; pairing it with a few Georgia natives keeps local pollinators fed too.

Common Questions About Growing Vietnamese Coriander in Georgia
When can I plant Vietnamese Coriander 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 Vietnamese Coriander, 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 Vietnamese Coriander grown in across Georgia?
Georgia spans USDA hardiness zones 7a-9b (USDA ARS PHZM 2023). Vietnamese Coriander 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 Georgia site have?
A typical Georgia site sees ~275 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Vietnamese Coriander needs 120+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
Is Vietnamese Coriander native to Georgia?
No — the USDA PLANTS Database lists Vietnamese Coriander as introduced rather than native in the Lower 48, so it is not part of Georgia's native flora. It grows here as a garden plant; pairing it with a few Georgia natives keeps local pollinators fed too.
How should I amend the soil for Vietnamese Coriander in Georgia?
Vietnamese Coriander prefers pH 5.5-7.5 and poorly (saturated >50% of year) drainage (Growable Ground Plant Database). 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.
