Odell, Oregon, sits in USDA hardiness zone 7b — a zone band wide enough that plant choice, not possibility, is the interesting question.
Well-matched crops include cabbage, prickly pear, california poppy, 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 Odell, 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 Odell 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 Odell
Each reading below is measured for Odell itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredOdell runs about 222 days between hard freezes — 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.

Winter hardiness
MeasuredOdell sits in USDA hardiness zone 7b.
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 Odell is in
Odell sits in the Eastern Cascades Slopes and Foothills — EPA Level III, inside the wider Northwestern Forested Mountains. That is read at Odell's own centroid, and it is not what its county reads: Hood River County is mostly Cascades. The wider page above you is answering a different question about different ground.

Is it too late to plant in Odell?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Feb 21; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 21 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 29 — 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 Odell, two things run higher than the national average within ~10 miles of Odell — Superfund (3 sites) and Underground Storage Tanks (137 sites). It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Superfund: Superfund sites represent the most severe contamination in the federal system.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Commission professional soil testing before any food production (test for heavy metals, VOCs, and SVOCs).
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Odell
Everything above resolves to Odell as a whole — one PHZM band and one 28°F frost record, read across 1K 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 Odell
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 Odell’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 Odell
When does frost risk typically end in Odell?
The last hard freeze (28°F) in Odell typically lands around Mar 21, 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 Apr 11.
When is the first frost in Odell?
The first hard freeze (28°F) in Odell typically arrives around Oct 29, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Oct 15, so the watching starts about Sep 29 — about 222 days after the spring freeze cleared.
How long is the growing season in Odell?
Measured between 28°F hard freezes, Odell sees about 222 frost-free days — roughly Mar 21 through Oct 29, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 11 to Oct 15, about 187 days.
Is the soil safe to grow vegetables in Odell?
The federal record around Odell is a meaningful one — 185 documented sites, mostly Underground Storage Tanks entries (137), the nearest Underground Storage Tanks record about 0.4 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 Odell?
From about Sep 29 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 Oct 29 (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 Oct 29. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Odell's scale — its 7b band and its 222-day season. Your yard writes its own version of Odell's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
