Plants matched to Orin's USDA zones 5a-6b — each links to its full growing profile.

Is it too late to plant in Orin?

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 1; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 29 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 12 — long-season crops need about 90 days of runway, quick greens only 30. Even past midsummer there is room for a true fall garden here, and garlic planted near the close carries the momentum into next year.

Growing Challenges in Wyoming

What an experienced grower plans around here — each one has a move.

Extremely short growing season (60-90 frost-free days)

At 60-90 frost-free days, a greenhouse or high tunnel isn't optional equipment — it's where the season actually happens.

Very low rainfall requires irrigation

Drip irrigation under mulch makes scarce water go the distance — build the system before the first bed.

Persistent high winds desiccate and damage plants

Windbreaks first, plants second — a sheltered bed loses a fraction of the moisture an exposed one does.

For cultivar selection, pest pressure, and planting-time guidance specific to Wyoming, the University of Wyoming Extension is the authoritative local source.

Know Before You Grow

  • Test well water for nitrates if you rely on a private well. Levels above 10 mg/L require treatment.
  • Raised beds with imported soil can reduce exposure risk near brownfield sites.
  • TRI facilities report chemical releases. Check wind direction — downwind parcels face higher airborne exposure.

Frequently Asked Questions

What hardiness zone is Orin, Wyoming?

Orin sits in USDA hardiness zones 5a-6b, per the USDA Plant Hardiness Zone Map 2023. Zones reflect average annual extreme minimum temperatures from 1991–2020 weather data.

Is it too late to plant in Orin?

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 1; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Apr 29 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 12 — long-season crops need about 90 days of runway, quick greens only 30. Even past midsummer there is room for a true fall garden here, and garlic planted near the close carries the momentum into next year.

When does frost risk typically end in Orin?

The last hard freeze (28°F) in Orin typically lands around Apr 29, per NOAA 1991–2020 climate normals — an earlier marker than the light-frost dates many planting charts quote. That marks the hard freeze, not the last light frost — light frosts can still bite for a few more weeks, so tender transplants usually wait another 2–3 weeks.

When is the first frost in Orin?

The first hard freeze (28°F) in Orin typically arrives around Oct 12, per NOAA 1991–2020 climate normals — the point most tender summer crops finish. Lighter frosts usually reach a couple of weeks earlier, so watch the forecast from late summer on and harvest or cover tender plants before the first cold night.

What vegetables grow in Orin?

Orin's zones 5a-6b support a wide range — strong performers include Potato, Indian Paintbrush, Cottonwood, Rhubarb, and Chokecherry. What actually takes on any one site comes down to its soil, sun, and drainage, and we score each plant against the real conditions at your address.

Which hardiness zone is Orin, really?

Officially, Orin sits in USDA zones 5a-6b (USDA PHZM 2023) — but a zone is a 30-year average of winter's coldest night across an area, and it can't see any one yard. A south-facing slope, a tree line, or a low frost pocket can shift a single site by half a zone either way, which is why neighboring gardeners often quote different numbers. We read the conditions at your exact address — soil, sun, slope, and frost — and score 1,112 plants against what's actually there.

Is the soil safe to grow vegetables in Orin?

The federal record around Orin is light — 20 documented sites across the 9 federal source types we checked — 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 I protect my plants from frost in Orin?

As the season closes around the first 28°F hard freeze near Oct 12 (NOAA 1991–2020 climate normals), a few moves buy time: cover tender plants with floating row cover or an old sheet on still, clear nights, water the soil the afternoon before a freeze so it holds warmth overnight, and harvest frost-tender crops like tomatoes, peppers, and basil before the first hard night. Hardy greens and root crops shrug off light frost and often sweeten after it, so leave them in.
