Nevada is not one climate
Nevada’s winter-low ladder runs across 17 counties, from zone 5 in Elko County to zone 9 in Clark County. That is 40°F between the two counties’ average coldest night — the difference between lemongrass overwintering in the ground and coming under cover.
The middle half of 17 counties runs 6.5–7 zones, with a median of 7 zones — a 4-zone span end to end.
Measured across 17 Nevada 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 Nevada
Lemongrass is rated for zones 10–11 — a cold floor USDA puts at 30 to 40°F. No Nevada 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 Nevada 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 Nevada
The frost window
Across Nevada, the last spring hard freeze (28°F) clears between Apr 28 and May 20, and the first fall hard freeze lands between Oct 9 and Oct 21 (NOAA Regional Climate Centers ACIS, 1991-2020). Counting from the latest last freeze to the earliest first freeze, that's a 142-day window you can count on — up to 176 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 Nevada's late-side last freeze of May 20 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 Nevada runs as cold as zone 4, 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.
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 survives winter in part of Nevada, not across all of it. Whether the season is long enough — and warm enough — is a different question.
Frost-free days
Lemongrass wants 120+ frost-free days; a typical Nevada site sees ~163 (NOAA Regional Climate Centers ACIS, 1991-2020). That leaves a workable window — start indoors to bank time.
Growing degree days
Lemongrass needs ~3000 GDD (base 50°F) to ripen. The state median runs ~1725 GDD (from PRISM 1991-2020 climate normals), so Nevada's typical season runs short on heat — pick a south-facing site and consider season extension.
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 Nevada. 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 Nevada soil test result is a problem or just a number. Drainage matters: this plant wants well (dry spells). If your Nevada site is heavier clay or sits in a low spot, raised beds or amendment with compost solve it.

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 Nevada’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 Nevada — and how to grow with it.
We checked the federal record across Nevada — 16,813 documented sites across 8 of the 9 source types we track.
The most significant on record: 127 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Nevada 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 with clean imported soil grow well almost anywhere in the meantime.

What an experienced grower watches for around here
In and around Nevada, Mining runs higher than the national average — 6,064 sites across Nevada. That's not a problem with your land — it's information about it.
Mining: Mining sites — both historic and active — can leach heavy metals (arsenic, lead, cadmium, mercury) into soil and water for centuries after operations cease.
Test soil for heavy metals (lead, arsenic, cadmium, mercury) — this is essential near any mining site.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.
What Else to Consider for Lemongrass in Nevada
Zone compatibility tells you about winter cold survival — but Nevada growers also need to think about:
Extremely low rainfall (driest US state)
Alkaline soils (pH 8-9) limit many species
Extreme summer heat in southern valleys
What to actually do about these — and the constraints that apply to every Nevada grower, not just lemongrass — is covered on the Nevada growing guide.
Timing shifts within Nevada
Lemongrass needs about 120 days of frost-free season to complete its cycle. 16 of Nevada’s 17 counties give it that outright. The tightest that does is Nye County at 128 frost-free days — 8 to spare. Below that line you are transplanting or extending the season, not direct-sowing.
Across Nevada’s 17 counties the frost-free season runs from 110 days in Elko County to 321 days in Clark County — a spread of 211 days, which is why a single statewide planting date misleads. The median Nevada county sees 163 frost-free days, leaving lemongrass about 43 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.

Is Lemongrass native to Nevada?
No — the USDA PLANTS Database lists Lemongrass as introduced rather than native in the Lower 48, so it is not part of Nevada's native flora. It grows here as a garden plant; pairing it with a few Nevada natives keeps local pollinators fed too.

Common Questions About Growing Lemongrass in Nevada
When can I plant Lemongrass in Nevada?
Nevada's last spring hard freeze (28°F) clears between Apr 28 and May 20, and the first fall hard freeze lands between Oct 9 and Oct 21 (NOAA Regional Climate Centers ACIS, 1991-2020). Lemongrass overwinters only from USDA zone 8 and warmer, and Nevada runs as cold as zone 4, 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 Nevada?
Nevada spans USDA hardiness zones 4a-10a (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 Nevada site have?
A typical Nevada site sees ~163 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.
Is Lemongrass native to Nevada?
No — the USDA PLANTS Database lists Lemongrass as introduced rather than native in the Lower 48, so it is not part of Nevada's native flora. It grows here as a garden plant; pairing it with a few Nevada natives keeps local pollinators fed too.
How should I amend the soil for Lemongrass in Nevada?
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 Nevada site — amend for drainage and organic matter first.
