Peoria, Oregon, sits in USDA hardiness zone 8b — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
A short list that earns its place here — cabbage, fig, california poppy, and collard greens — with any one site's soil, sun, and drainage making the final cut.
Even in Peoria, 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 Peoria 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 Peoria
Each reading below is measured for Peoria itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsPeoria runs about 258 days between hard freezes (read from Linn County, the closest normal to Peoria) — a long growing season.
There is slack for succession plantings and slow-finishing crops: many vegetables can be sown twice, and the heat-lovers have time to ripen fully.
Plan a second sowing of quick crops after the first comes out, and use the fall window most gardeners let sit idle.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredPeoria sits in USDA hardiness zone 8b.
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 Peoria is in
Peoria sits in the Willamette Valley — EPA Level III, inside the wider Marine West Coast Forest. That is read at Peoria's own centroid, and it is not what its county reads: Linn County is mostly Cascades. The wider page above you is answering a different question about different ground.

Is it too late to plant in Peoria?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Feb 10; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 10 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 23 — long-season crops need about 90 days of runway, quick greens only 30. With a season this long, “too late” mostly means “switch crops” — second sowings and a full fall garden are the norm, with garlic closing the year.

What an experienced grower watches for around here
In and around Peoria, two things run higher than the national average within ~10 miles of Peoria — Superfund (9 sites) and CAFO (4 sites). Knowing it is half the work — and it's nothing a thoughtful grower can't plan for.
Superfund: Superfund sites represent the most severe contamination in the federal system.
CAFO: CAFOs pose a different contamination profile than chemical sources.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.

Your land is one point inside Peoria
Everything above resolves to Peoria as a whole — one PHZM band, read across 304 acres, with hard-freeze dates borrowed from Linn County’s record because no 30-year normal resolves at this town’s own centroid. 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 Peoria
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 Linn County’s record, because none resolves here; 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 Peoria
When does frost risk typically end in Peoria?
The last hard freeze (28°F) in Peoria typically lands around Mar 10, 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 Mar 31.
When is the first frost in Peoria?
The first hard freeze (28°F) in Peoria typically arrives around Nov 23, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 9, so the watching starts about Oct 24 — about 258 days after the spring freeze cleared.
How long is the growing season in Peoria?
Measured between 28°F hard freezes, Peoria sees about 258 frost-free days — roughly Mar 10 through Nov 23, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 31 to Nov 9, about 223 days.
Is the soil safe to grow vegetables in Peoria?
The federal record around Peoria is a meaningful one — 313 documented sites, mostly Underground Storage Tanks entries (163), the nearest Nitrate record about 1.2 miles out — so a soil test before new food beds is a sensible precaution here, not a reason to hold back from growing. Remember that proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what sits where.
How do I protect my plants from frost in Peoria?
From about Oct 24 the job here turns from planting to protecting — the last start even a 30-day crop can finish. As the season closes around the first 28°F hard freeze near Nov 23 (NOAA 1991–2020 climate normals), three moves buy time: row cover or an old sheet over tender plants on still, clear nights; water the soil the afternoon before a freeze, so it holds warmth overnight; and harvest tomatoes, peppers and basil before Nov 23. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.

- Soil character — no town-scale survey exists, so Peoria's 304 acres read through its county's SSURGO summaryfrom Linn County
- Growing-degree days and winter chill — measured county-wide only, so the county page carries themfrom Linn County
