Eden, Wyoming, sits in USDA hardiness zone 4a — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Expect okra, cranberry, cilantro, and zucchini to be strong candidates here; the deciding factors on any one parcel stay local — soil, sun, and drainage.
Even in Eden, 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 Eden 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 Eden
Each reading below is measured for Eden itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredEden runs about 116 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.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredEden sits in USDA hardiness zone 4a.
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.
USDA PHZM 2023
The kind of country Eden is in
Eden sits in the Wyoming Basin — EPA Level III, inside the wider North American Deserts. That is read at Eden's own centroid rather than borrowed from Sweetwater County.

Is it too late to plant in Eden?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Apr 26; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 24 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 17 — long-season crops need about 90 days of runway, quick greens only 30. Even here the calendar’s edges hold value: thirty-day greens late in the window, then garlic and a rested bed for spring.

What an experienced grower watches for around here
In and around Eden, Nitrate runs higher than the national average — 22 sites within ~10 miles of Eden. Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Nitrate: Nitrate contamination primarily comes from agricultural fertilizer runoff and failing septic systems.
Test well water for nitrate if you rely on a private well for irrigation (EPA standard: 10 mg/L).

Your land is one point inside Eden
Everything above resolves to Eden as a whole — one PHZM band and one 28°F frost record, read across 9K 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 Eden
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 Eden’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 Eden
When does frost risk typically end in Eden?
The last hard freeze (28°F) in Eden typically lands around May 24, 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 14.
When is the first frost in Eden?
The first hard freeze (28°F) in Eden typically arrives around Sep 17, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 3, so the watching starts about Aug 18 — about 116 days after the spring freeze cleared.
How long is the growing season in Eden?
Measured between 28°F hard freezes, Eden sees about 116 frost-free days — roughly May 24 through Sep 17, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 14 to Sep 3, about 81 days.
Is the soil safe to grow vegetables in Eden?
The federal record around Eden is light — 38 documented sites across the 9 federal source types we checked, mostly Nitrate entries (22), the nearest Underground Storage Tanks record under a tenth of a mile out — and proximity to a documented site is information, not a diagnosis of any one yard. Growing food here starts from a strong position; a soil test before new food beds settles any site-specific question.
How do gardeners stretch the season in Eden?
With about 116 frost-free days between hard freezes, Eden 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 144 to 172 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 24 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Eden's scale — its 4a band and its 116-day season. Your yard writes its own version of Eden's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
