Unlikely — Zone Mismatch
lemongrass (zones 10-11) does not overlap with Mississippi's zone range (7b-9b). Growing outdoors is unlikely without significant protection.
One zone short — what would close it
Lemongrass is hardy to zone 10, and the warmest ground in Mississippi is zone 9 — 1 zone short. Planted in open ground it will not survive a Mississippi winter. To grow it here, grow lemongrass in a container and move it under cover for the coldest weeks, or give it a greenhouse.
Season extension and overwintering under cover both work at this margin. How to buy the weeks →

When to Plant Lemongrass in Mississippi
The frost window
Across Mississippi, the last spring hard freeze (28°F) clears between Feb 17 and Mar 3, and the first fall hard freeze lands between Nov 21 and Nov 30 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 263-day window you can count on — up to 286 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 — its listed minimum temperature is 64.4°F (USDA PLANTS Database) — 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.
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 Mississippi's late-side last freeze of Mar 3 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; Missouri Botanical Garden Plant Finder) — but Mississippi runs as cold as zone 7, 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 — Tishomingo 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 lemongrass does not survive a Mississippi 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 Mississippi under protection.
Frost-free days
Lemongrass wants 120+ frost-free days; a typical Mississippi site sees ~273 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves comfortable headroom for succession planting.
Growing degree days
Lemongrass needs ~3000 GDD (base 50°F) to ripen. The state median runs ~5404 GDD (from PRISM 1991-2020 climate normals), so Mississippi'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 Mississippi. 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 Mississippi soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Mississippi 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 30.3% of Mississippi 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.

What Else to Consider for Lemongrass in Mississippi
Zone compatibility tells you about winter cold survival — but Mississippi growers also need to think about:
Extreme summer heat and humidity
Heavy alluvial clay in the Delta region
Frequent severe storms and flooding
Growing lemongrass here specifically
Lemongrass needs sharp drainage and sends medium roots hardy to about 64°F; in Mississippi, about 30.3% of soils are poorly-drained (SSURGO), and standing water is what actually kills it.

What to actually do about these — and the constraints that apply to every Mississippi grower, not just lemongrass — is covered on the Mississippi growing guide.
Timing shifts within Mississippi
Mississippi isn't one climate. In Tishomingo County, the last hard freeze (28°F) holds until about Mar 23 — roughly 26 days later than the recorded state median — so plant lemongrass to your county's window, not the statewide date.
Lemongrass needs about 120 days of frost-free season to complete its cycle. Even Tishomingo County — Mississippi’s shortest season at 232 frost-free days — clears that by 112 days, so season length isn’t the constraint anywhere in Mississippi. What varies is your own parcel.
Across Mississippi’s 82 counties the frost-free season runs from 232 days in Tishomingo County to 309 days in Harrison County — a spread of 77 days, which is why a single statewide planting date misleads. The median Mississippi county sees 273 frost-free days, leaving lemongrass about 153 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"). Lemongrass's 120-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.
Recommended Lemongrass Varieties for Mississippi
Mississippi publishes no state variety trial for lemongrass, so we won't invent a "best for Mississippi" list. Choose types rated to your USDA hardiness zone (7b-9b), and confirm winter survival and drainage against your own parcel.
Mississippi Cooperative Extension
For Mississippi-specific cultivar recommendations, planting calendars, and pest pressure for lemongrass, the canonical source is Mississippi State University Extension Service. Their fact sheets carry the local trial data we can't generalize across 50 states.
Is Lemongrass native to Mississippi?
No — the USDA PLANTS Database lists Lemongrass as introduced rather than native in the Lower 48, so it is not part of Mississippi's native flora. It grows here as a garden plant; pairing it with a few Mississippi natives keeps local pollinators fed too.

Common Questions About Growing Lemongrass in Mississippi
When can I plant Lemongrass in Mississippi?
Mississippi's last spring hard freeze (28°F) clears between Feb 17 and Mar 3, and the first fall hard freeze lands between Nov 21 and Nov 30 (NOAA Regional Climate Centers ACIS, 1991-2020). Lemongrass overwinters only from USDA zone 8 and warmer, and Mississippi runs as cold as zone 7, 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 Mississippi?
Mississippi spans USDA hardiness zones 7b-9b (USDA ARS PHZM 2023). Lemongrass carries a range of zones 10-11, so the overlap zones are where outdoor growing is most reliable.
How many frost-free days does a typical Mississippi site have?
A typical Mississippi site sees ~273 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 Tishomingo, the freeze-free season runs shorter than the state average, so verify your own county's window.
Is Lemongrass native to Mississippi?
No — the USDA PLANTS Database lists Lemongrass as introduced rather than native in the Lower 48, so it is not part of Mississippi's native flora. It grows here as a garden plant; pairing it with a few Mississippi natives keeps local pollinators fed too.
How should I amend the soil for Lemongrass in Mississippi?
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 Mississippi site — amend for drainage and organic matter first.
