Alpine Northeast, Wyoming, sits in USDA hardiness zone 5a — a zone band wide enough that plant choice, not possibility, is the interesting question.
On paper, okra, cranberry, lavender, and pumpkin all suit these conditions — on the ground, soil, sun, and drainage make the final call.
Even in Alpine Northeast, 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 Alpine Northeast 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 Alpine Northeast
Each reading below is measured for Alpine Northeast itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredAlpine Northeast runs about 113 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
MeasuredAlpine Northeast 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 Alpine Northeast is in
Alpine Northeast sits in the Middle Rockies — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at Alpine Northeast'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 Alpine Northeast?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around May 6; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jun 3 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Sep 24 — 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.

What an experienced grower watches for around here
In and around Alpine Northeast, Nitrate runs higher than the national average — 22 sites within ~10 miles of Alpine Northeast. That's not a problem with your land — it's information about 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 Alpine Northeast
Everything above resolves to Alpine Northeast 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 Alpine Northeast
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 Alpine Northeast’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 Alpine Northeast
When does frost risk typically end in Alpine Northeast?
The last hard freeze (28°F) in Alpine Northeast typically lands around Jun 3, 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 24.
When is the first frost in Alpine Northeast?
The first hard freeze (28°F) in Alpine Northeast typically arrives around Sep 24, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 10, so the watching starts about Aug 25 — about 113 days after the spring freeze cleared.
How long is the growing season in Alpine Northeast?
Measured between 28°F hard freezes, Alpine Northeast sees about 113 frost-free days — roughly Jun 3 through Sep 24, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 24 to Sep 10, about 78 days.
Is the soil safe to grow vegetables in Alpine Northeast?
The federal record around Alpine Northeast is light — 37 documented sites across the 9 federal source types we checked, mostly Nitrate entries (22), the nearest Nitrate record about 1.1 miles 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 Alpine Northeast?
With about 113 frost-free days between hard freezes, Alpine Northeast 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 141 to 169 days — and cold frames or low tunnels buy more. Starting transplants indoors ahead of the Jun 3 hard-freeze normal stretches the season without touching the calendar.
Everything above is measured at Alpine Northeast's scale — its 5a band and its 113-day season. Your yard writes its own version of Alpine Northeast's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
