Owyhee, Nevada, sits in USDA hardiness zone 6a — a zone band wide enough that plant choice, not possibility, is the interesting question.
The conditions favor cabbage, blackberry, california poppy, and collard greens, among others — though every individual site edits that list with its own soil, sun, and drainage.
Even in Owyhee, no two yards are alike.
A low spot, a south-facing slope, or a stand of trees moves the frost date and sun across a single Owyhee lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

What this means for growing in Owyhee
Each reading below is measured for Owyhee itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
MeasuredOwyhee runs about 142 days between hard freezes — a short growing season.
Long-maturing crops like melons, sweet potatoes, and winter squash can run out of runway before the first hard freeze, ripening late or not at all.
Lead with fast-maturing varieties, and stretch the season on both ends with cold frames, low tunnels, or a greenhouse.

Winter hardiness
MeasuredOwyhee sits in USDA hardiness zone 6a.
The zone sets which perennials, shrubs, and fruit trees live through an average winter here — a plant rated for a colder zone is a safe bet, one rated warmer needs winter protection or gets treated as an annual.
Match perennials and fruit to the zone before you buy, so nothing you plant is a gamble against the cold.

The kind of country Owyhee is in
Owyhee sits in the Northern Basin and Range — EPA Level III, inside the wider North American Deserts. That is read at Owyhee's own centroid, and it is not what its county reads: Elko County is mostly Central Basin and Range. The wider page above you is answering a different question about different ground.

Every plant below cleared Owyhee's own zone 6a and its 142-day season. Each card opens that plant's Nevada profile. How we score.






























Is it too late to plant in Owyhee?
Rarely: the season closes in stages, not all at once, and each stage has its crops. Cool-season crops can go in from around Apr 15; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 13 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 2 — long-season crops need about 90 days of runway, quick greens only 30. Short seasons reward decisiveness — quick-maturing varieties late, hardy greens under cover, and next year’s garlic in the ground before it closes.

Your land is one point inside Owyhee
Everything above resolves to Owyhee as a whole — one PHZM band and one 28°F frost record, read across 144K acres. Your parcel is one point inside that footprint. Slope, tree cover, a low spot that pools cold air, and what is in the soil are all resolved at the address, and none of them are visible at town scale. That is the honest boundary of this page, and the reason the next step is a reading of your own ground rather than a better local average.

How we know this about Owyhee
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this town’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Owyhee’s own record; boundaries and acreage from US Census TIGER/Line 2025; the contamination records from the federal sources named in their beats above. Soil is not read at town grain anywhere on this page — there is no town-resolution survey in our data, which is why you will find no soil grid here rather than a statewide one wearing a local label. The resolution ledger below names every figure this page inherited.
Common questions about Owyhee
When does frost risk typically end in Owyhee?
The last hard freeze (28°F) in Owyhee typically lands around May 13, per NOAA 1991–2020 climate normals — earlier than the light-frost dates most charts quote. That marks the hard freeze, not the last light frost — lighter frosts keep biting past it, which is why tender transplants here wait until about Jun 3.
When is the first frost in Owyhee?
The first hard freeze (28°F) in Owyhee typically arrives around Oct 2, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 18, so the watching starts about Sep 2 — about 142 days after the spring freeze cleared.
How long is the growing season in Owyhee?
Measured between 28°F hard freezes, Owyhee sees about 142 frost-free days — roughly May 13 through Oct 2, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 3 to Sep 18, about 107 days.
Is the soil safe to grow vegetables in Owyhee?
The federal record around Owyhee shows 7 documented sites, mostly Mining entries (4), the nearest Mining record about 4.2 miles out — a typical footprint for a growing area, and proximity to a documented site is information, not a diagnosis of any one yard. It's worth seeing which recorded sites sit closest to where you grow, and testing the soil before new food beds near any of them.
How do gardeners stretch the season in Owyhee?
With about 142 frost-free days between hard freezes, Owyhee rewards the classic extension moves: floating row cover buys roughly two to four extra weeks at each shoulder — on this season that is a working window nearer 170 to 198 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 13 hard-freeze normal stretches the season without touching the calendar.
