Unlikely — Zone Mismatch
lemongrass (zones 10-11) does not overlap with North Carolina's zone range (6a-9a). Growing outdoors is unlikely without significant protection.
2 zones short — what would close it
Lemongrass is hardy to zone 10, and the warmest ground in North Carolina is zone 8 — 2 zones short. Planted in open ground it will not survive a North Carolina winter. To grow it here, grow lemongrass in an earth-sheltered greenhouse — its modeled 2.5-zone lift covers this gap.

North Carolina is not one climate
North Carolina’s winter-low ladder runs across 100 counties, from zone 6.5 in Avery County to zone 9 in Dare County. That is 25°F between the two counties’ average coldest night — the difference between lemongrass overwintering in the ground and coming under cover.
The middle half of 100 counties runs 7.5–8 zones, with a median of 8 zones — a 2.5-zone span end to end.
Measured across 100 North Carolina counties. USDA PHZM 2023, per county. Quartiles are order statistics — every figure shown is a value a real county recorded, not an interpolation. Your own site sits somewhere inside this range; a parcel report resolves where.
Where Lemongrass Stands in North Carolina
Lemongrass is rated for zones 10–11 — a cold floor USDA puts at 30 to 40°F. No North Carolina county sits inside it, so in open ground this is a grown-under-cover plant here rather than a bed plant — which is a statement about North Carolina winters, not about lemongrass.

County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. A zone is a 10°F band of average annual extreme minimum temperature, so the floor above is the band the plant's rating denotes, not a single measured kill point. Slope, shelter and cold-air drainage routinely move a site half a zone either way from its county figure — which is the part only your address resolves.

When to Plant Lemongrass in North Carolina
The frost window
Across North Carolina, the last spring hard freeze (28°F) clears between Mar 11 and Mar 24, and the first fall hard freeze lands between Nov 10 and Nov 25 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 231-day window you can count on — up to 259 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.
Frost tenderness
Lemongrass is frost-tender — FAO ECOCROP puts its killing temperature at 32°F — so set plants out two to three weeks PAST your local last hard freeze, not on it and not on the state's earliest date. The 28°F marker above is when killing freezes stop, not when light frost does. That is the point where cold damages growing tissue, not a winter-survival floor — an established perennial comes through far colder while dormant, which is what its hardiness zone tells you.
When to start the seed
Those dates are when lemongrass goes out, not when it starts. It is sown under cover about 10 weeks ahead, so counting back from North Carolina's late-side last freeze of Mar 24 is what fixes your sowing date — and a yard that clears frost earlier than the state's late date starts earlier still.
Grown as an annual here
Lemongrass is a true perennial in its home range — it overwinters from USDA zone 8 and warmer (NC State Extension Gardener Plant Toolbox) — but North Carolina runs as cold as zone 6, so it is killed back each winter and replanted each spring. Treat it on the season schedule above, not as a permanent planting: there is no fall establishment window for it here.
Timing tuned to sub-state frost dates — Swain County, not the statewide average.
Frost window: NOAA Climate Normals 1991-2020. Plant timing fields: Growable Ground Plant Database — frost-free days from FAO ECOCROP, days to harvest from university Extension production guides, and growing-degree-day and chill-hour minimums that are compilation estimates rather than published figures. 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 lemongrass does not survive a North Carolina 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 North Carolina under protection.
Growing degree days
Lemongrass needs ~3000 GDD (base 50°F) to ripen. We haven't confirmed this against a published source yet. The state median runs ~4537 GDD (from PRISM 1991-2020 climate normals), so North Carolina'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
Lemongrass tolerates a wide pH range (pH 4.3-7.3) — 3 units, acid ground through alkaline — so soil acidity is rarely what limits it in North Carolina. A soil test is still worth having, but for what else it tells you about this site, not to clear this plant. It will grow across that whole span, but it does best between pH 5 and 5.8 — worth knowing before you decide whether a North Carolina soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your North Carolina site is heavier clay or sits in a low spot, a raised bed lifts the roots above wet ground, or work in compost.
Your land, not the state average
SSURGO maps about 14.7% of North Carolina as poorly or somewhat-poorly drained, and the class flips parcel to parcel. Lemongrass has low drought tolerance, so it is the fast-draining end that will cost you — your soil map unit, not the state average, is the real answer.

Before you plant lemongrass for food
Anything you grow to eat takes up what is in the ground it grows in, so what is on record near you is worth knowing before lemongrass goes in. What follows is North Carolina’s documented federal record at state scale — a screening signal, not a soil test, and not a statement about any one lot.
Safe to Grow Here?
What the federal record shows across North Carolina — and how to grow with it.
We checked the federal record across North Carolina — 33,708 documented sites across 7 of the 8 source types we track.
The most significant on record: 464 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
North Carolina carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds of imported, lab-tested soil grow well almost anywhere in the meantime.

What Else to Consider for Lemongrass in North Carolina
Zone compatibility tells you about winter cold survival — but North Carolina growers also need to think about:
Red Piedmont clay is hard to work and drains poorly
Humidity drives significant disease pressure
Hurricane risk on the coastal plain
Growing lemongrass here specifically
Lemongrass needs sharp drainage and sends medium roots; its growing tissue takes cold to about 32°F (FAO ECOCROP), but in North Carolina, about 14.7% of soils are poorly-drained (SSURGO), and standing water is what actually kills it.
Build lemongrass up on a coarse, free-draining mound so its crown never sit in saturated soil. How to handle it →
What to actually do about these — and the constraints that apply to every North Carolina grower, not just lemongrass — is covered on the North Carolina growing guide.
Timing shifts within North Carolina
North Carolina isn't one climate. In Swain County, the last hard freeze (28°F) holds until about Apr 27 — roughly 41 days later than the recorded state median — so plant lemongrass to your county's window, not the statewide date.
County last-freeze dates: NOAA Regional Climate Centers ACIS (1991-2020), county 28°F freeze (earlier than the folk 32°F "last frost"). A parcel report resolves your address's own frost dates.
Where in North Carolina Lemongrass Is Zone-Hardy
Lemongrass is rated for USDA zones 10–11. No North Carolina county reaches it. Even Dare County, the state’s mildest winter at zone 9a, sits below the plant’s zone 10 floor — so in open ground this one needs winter protection here, or a container that comes under cover.
Across those 100 counties North Carolina’s winter-low ladder runs from zone 6b in Avery County to zone 9a in Dare County — 2.5 USDA zones of spread, which is 25°F between the two counties’ average coldest night of the year. None of that range reaches the band lemongrass needs, so here the statewide answer really is the answer.
County hardiness zones: USDA Plant Hardiness Zone Map (PHZM) 2023, per county. Lemongrass’s zone 10–11 band: Not verified — NC State Extension Gardener Plant Toolbox lists zones 8b–11b. A parcel report resolves your address’s own zone and frost dates rather than its county’s.
Good to Know Before You Plant Lemongrass
Lemongrass is listed as toxic to dogs, cats, horses. (Source: NC State Extension Gardener Plant Toolbox.) Most listed plants only cause brief upset — a raised bed or a fenced corner usually keeps curious pets clear. Worth knowing for placement: in North Carolina this is a one-season plant and the first hard freeze (Nov 10 - Nov 25) takes it down, so the exposure above is a summer-long one rather than something standing in the bed all year.
Recommended Lemongrass Varieties for North Carolina
North Carolina publishes no state variety trial for lemongrass, so we won't invent a "best for North Carolina" list. Choose types rated to your USDA hardiness zone (6a-9a), and confirm winter survival and drainage against your own parcel.
North Carolina Cooperative Extension
For North Carolina-specific cultivar recommendations, planting calendars, and pest pressure for lemongrass, the canonical source is NC State Extension. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Lemongrass native to North Carolina?
No — the USDA PLANTS Database lists Lemongrass as introduced rather than native in the Lower 48, so it is not part of North Carolina's native flora. It grows here as a garden plant; pairing it with a few North Carolina natives keeps local pollinators fed too.
Looking for plants that belong here? The North Carolina growing guide lists plants that USDA PLANTS records growing in North Carolina and that Kew and NatureServe Explorer both list in its native range, leaving out any that NatureServe flags as exotic there or that our audit holds.

Common Questions About Growing Lemongrass in North Carolina
When can I plant Lemongrass in North Carolina?
North Carolina's last spring hard freeze (28°F) clears between Mar 11 and Mar 24, and the first fall hard freeze lands between Nov 10 and Nov 25 (NOAA Regional Climate Centers ACIS, 1991-2020). Lemongrass overwinters only from USDA zone 8 and warmer, and North Carolina runs as cold as zone 6, so it is grown as an annual here — plant it after the last hard freeze, two to three weeks later for tender stock, and expect to replant next spring rather than establishing it for the long term.
What hardiness zone is Lemongrass grown in across North Carolina?
North Carolina spans USDA hardiness zones 6a-9a (USDA ARS PHZM 2023). Lemongrass is listed for zones 10-11, which do not overlap them, so there is no zone in North Carolina where this page can call outdoor growing reliable. A parcel report resolves your own address's zone.
How many frost-free days does a typical North Carolina site have?
A typical North Carolina site sees ~245 frost-free days per year (derived from NOAA Regional Climate Centers ACIS, 1991-2020). Lemongrass needs 120+ 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 Swain, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Lemongrass native to North Carolina?
No — the USDA PLANTS Database lists Lemongrass as introduced rather than native in the Lower 48, so it is not part of North Carolina's native flora. It grows here as a garden plant; pairing it with a few North Carolina natives keeps local pollinators fed too.
How should I amend the soil for Lemongrass in North Carolina?
Lemongrass tolerates pH 4.3-7.3 and well (dry spells) drainage (FAO ECOCROP). That is a 3-unit span, acid ground through alkaline, so pH is rarely what limits this plant on a North Carolina site — amend for drainage and organic matter first.
