Norrie, Colorado, sits in USDA hardiness zone 5a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
Growers here do well with okra, cranberry, lavender, and pumpkin — with the usual caveat that any single yard's soil, sun, and drainage cast the deciding vote.
Even in Norrie, 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 Norrie lot. Enter your address and we'll score 1,086 plants against your land's actual soil, sun, and frost.

Every figure names the dataset it came from. Hard-freeze dates are this town’s own 28°F normals: light frosts run a few weeks past them, and tender transplants usually wait 2–3 weeks after the last hard freeze.

What this means for growing in Norrie
Each reading below is measured for Norrie itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredNorrie runs about 110 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
MeasuredNorrie 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 Norrie is in
Norrie sits in the Southern Rockies — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at Norrie's own centroid rather than borrowed from Pitkin County.

Is it too late to plant in Norrie?
Almost never — the real question is what to plant next. 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 21 — 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 Norrie
Everything above resolves to Norrie as a whole — one PHZM band and one 28°F frost record, read across 120 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 Norrie
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 Norrie’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 Norrie
When does frost risk typically end in Norrie?
The last hard freeze (28°F) in Norrie 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 Norrie?
The first hard freeze (28°F) in Norrie typically arrives around Sep 21, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 7, so the watching starts about Aug 22 — about 110 days after the spring freeze cleared.
How long is the growing season in Norrie?
Measured between 28°F hard freezes, Norrie sees about 110 frost-free days — roughly Jun 3 through Sep 21, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Jun 24 to Sep 7, about 75 days.
Is the soil safe to grow vegetables in Norrie?
The federal record around Norrie runs heavier than most — 16 documented sites, mostly Mining entries (16), the nearest Mining record about 4.0 miles out — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
How do gardeners stretch the season in Norrie?
With about 110 frost-free days between hard freezes, Norrie 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 138 to 166 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.
