Generally — Most Areas
hyacinth (zones 4-8) suits most of Georgia (7a-9b) — zones 7-8 are in range, and the rest of the state is the exception.
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 hyacinth against your parcel's actual hardiness, soil, and sun.

When to Plant Hyacinth 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 hyacinth, so this page does not state whether it overwinters here — and gives no fall establishment date on the strength of a guess. Whether hyacinth 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.

What Else to Consider for Hyacinth 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 hyacinth — is covered on the Georgia growing guide.
Where in Georgia Hyacinth Is Zone-Hardy
Hyacinth is rated for USDA zones 4–8. 44 of Georgia’s 159 counties fall inside that band. The coldest that does is Fannin County at zone 7b. 115 counties sit above its zone 8 ceiling, where the limit is too little winter chill rather than too much cold. Where you are in Georgia decides this one.
Across those 159 counties Georgia’s winter-low ladder runs from zone 7b in Fannin County to zone 9a in Worth 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. Union County holds its last hard freeze (28°F) until about Apr 7, while Worth County is clear by Feb 7 — 59 days apart. Set hyacinth 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". Hyacinth’s zone 4–8 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 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 hyacinth (USDA PHZM 2023):
Pollinator + Wildlife Value
Hyacinth draws honeybees and native bees (moderate value, Growable Ground Plant Database). Planting it near vegetable beds can lift fruit set on neighboring crops. Outdoors, hyacinth 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 hyacinth, the canonical source is UGA Cooperative Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Hyacinth native to Georgia?
No — the USDA PLANTS Database lists Hyacinth 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 Hyacinth in Georgia
When can I plant Hyacinth 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 Hyacinth, 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 Hyacinth grown in across Georgia?
Georgia spans USDA hardiness zones 7a-9b (USDA ARS PHZM 2023). Hyacinth carries a range of zones 4-8, 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). Hyacinth 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 Hyacinth native to Georgia?
No — the USDA PLANTS Database lists Hyacinth 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.
Will Hyacinth actually grow on my specific land in Georgia?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores hyacinth against your address's exact soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
