Freedom, Wyoming, sits in USDA hardiness zone 5a — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
Well-matched crops include cabbage, cranberry, lavender, and collard greens, and the gap between "grows in the area" and "grows in your yard" is closed by soil, sun, and drainage.
Even in Freedom, 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 Freedom 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 Freedom
Each reading below is measured for Freedom itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
MeasuredFreedom runs about 123 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
MeasuredFreedom sits in USDA hardiness zone 5a.
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 Freedom is in
Freedom sits in the Middle Rockies — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at Freedom's own centroid, and it is not what its county reads: Lincoln County is mostly Wyoming Basin. The wider page above you is answering a different question about different ground.

Is it too late to plant in Freedom?
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 22; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 20 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 20 — long-season crops need about 90 days of runway, quick greens only 30. In a season this compact, fast finishers and cold-hardy greens do the late work, and garlic tucked in before the freeze repays you next summer.

A note from Gnorman
What an experienced grower watches for around here
In and around Freedom, Nitrate runs higher than the national average — 46 sites within ~10 miles of Freedom. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
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 Freedom
Everything above resolves to Freedom as a whole — one PHZM band and one 28°F frost record, read across 3K 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 Freedom
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 Freedom’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 Freedom
When does frost risk typically end in Freedom?
The last hard freeze (28°F) in Freedom typically lands around May 20, 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 10.
When is the first frost in Freedom?
The first hard freeze (28°F) in Freedom typically arrives around Sep 20, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 6, so the watching starts about Aug 21 — about 123 days after the spring freeze cleared.
How long is the growing season in Freedom?
Measured between 28°F hard freezes, Freedom sees about 123 frost-free days — roughly May 20 through Sep 20, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 10 to Sep 6, about 88 days.
Is the soil safe to grow vegetables in Freedom?
The federal record around Freedom shows 70 documented sites, mostly Nitrate entries (46), the nearest Nitrate record about 0.4 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 Freedom?
With about 123 frost-free days between hard freezes, Freedom 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 151 to 179 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the May 20 hard-freeze normal stretches the season without touching the calendar.
