Conditional — Some Areas
para grass (zones 10-13) reaches only part of Nevada (4a-10a): zone 10 are in range, so where you are in the state decides it.
Your yard isn't the whole zone.
Nevada spans zones 4a-10a, but your yard has its own microclimate — slope, trees, and low spots shift frost and sun across a single parcel. Enter your address and we'll score para grass against your land's actual soil, sun, and frost.

When to Plant Para Grass 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
Para Grass is frost-tender — its listed minimum temperature is 59°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.
Days to maturity vs. the window
At 90 days to maturity (USDA PLANTS Database), counting from the last hard freeze it ripens with 52 days to spare even in Nevada's tightest freeze scenario — room for a later start or a second sowing.
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 para grass 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
Para Grass 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
Para Grass 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
Para Grass tolerates a wide pH range (pH 4.3-7.7) — 3.4 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 6 — worth knowing before you decide whether a Nevada 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 Para Grass 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 para grass — is covered on the Nevada growing guide.
Timing shifts within Nevada
Para Grass 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 para grass 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"). Para Grass's 120-day requirement: USDA PLANTS / Growable Ground plant database (minimum frost-free days). A parcel report resolves your address's own frost dates.

Common Questions About Growing Para Grass in Nevada
When can I plant Para Grass 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). Para Grass is frost-tender — its listed minimum temperature is 59°F (USDA PLANTS Database) — so wait two to three weeks past your site's last hard freeze, when light frost has also stopped, before planting out.
Can Para Grass mature before first frost in Nevada?
Yes — Para Grass matures in 90 days (USDA PLANTS Database), and Nevada's dependable hard-freeze-free window runs 142 days (NOAA Regional Climate Centers ACIS, 1991-2020), leaving 52 days of margin. Plant once the last hard freeze has passed — two to three weeks later for anything tender — and it ripens ahead of the first fall freeze.
What hardiness zone is Para Grass grown in across Nevada?
Nevada spans USDA hardiness zones 4a-10a (USDA ARS PHZM 2023). Para Grass carries a range of zones 10-13, 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). Para Grass needs 120+ frost-free days, so check whether your local microclimate runs above or below the state average before settling on a planting date.
How should I amend the soil for Para Grass in Nevada?
Para Grass tolerates pH 4.3-7.7 and poorly (saturated >50% of year) drainage (FAO ECOCROP). That is a 3.4-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.
Will Para Grass actually grow on my specific land in Nevada?
State-level zone + climate data is a sketch. A Growable Ground parcel report scores para grass against your address's exact soil pH, drainage, sun, and frost-date data drawn from USDA SSURGO, NOAA, and PRISM — not state averages.
