Hubbard, Oregon, sits in USDA hardiness zone 9a — a range where zone-matched perennials and frost-aware annual timing set what succeeds.
A short list that earns its place here — kale, douglas fir, garlic, and hazelnut — with any one site's soil, sun, and drainage making the final cut.
Even in Hubbard, no two yards are alike.

What this means for growing in Hubbard
Each reading below is measured for Hubbard itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsHubbard runs about 243 days between hard freezes (read from Marion County, the closest normal to Hubbard) — 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
MeasuredHubbard sits in USDA hardiness zone 9a.
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.
USDA PHZM 2023
The kind of country Hubbard is in
Hubbard sits in the Willamette Valley — EPA Level III, inside the wider Marine West Coast Forest. That is read at Hubbard's own centroid rather than borrowed from Marion County.
What Grows in Hubbard
Plants matched to Hubbard's USDA zones 9a, ordered by how much hardiness margin each has here — the ones with room to spare at both ends of this town's band lead. Each links to its full growing profile.
Is it too late to plant in Hubbard?
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 23; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 23 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 21 — long-season crops need about 90 days of runway, quick greens only 30. Here the season winds down slowly: late sowings, a real autumn harvest, and garlic in the ground before the first hard freeze.

A note from Gnorman
What an experienced grower watches for around here
In and around Hubbard, two things run higher than the national average within ~10 miles of Hubbard — CAFO (13 sites) and PFAS (6 sites). That's not a problem with your land — it's information about it.
CAFO: CAFOs pose a different contamination profile than chemical sources.
PFAS: PFAS (per- and polyfluoroalkyl substances) are called "forever chemicals" because they do not biodegrade.
Wash all produce consumed raw thoroughly, especially leafy greens grown near CAFOs.
Test irrigation water source — this is the primary pathway for PFAS to reach garden crops.

Your land is one point inside Hubbard
Everything above resolves to Hubbard as a whole — one PHZM band, read across 513 acres, with hard-freeze dates borrowed from Marion County’s record because no 30-year normal resolves at this city’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 city 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 Hubbard
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at this city’s own centroid; hard-freeze dates from NOAA 1991–2020 28°F normals at Marion 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 city grain anywhere on this page — there is no city-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 Hubbard
When does frost risk typically end in Hubbard?
The last hard freeze (28°F) in Hubbard typically lands around Mar 23, 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 13.
When is the first frost in Hubbard?
The first hard freeze (28°F) in Hubbard typically arrives around Nov 21, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 7, so the watching starts about Oct 22 — about 243 days after the spring freeze cleared.
How long is the growing season in Hubbard?
Measured between 28°F hard freezes, Hubbard sees about 243 frost-free days — roughly Mar 23 through Nov 21, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Apr 13 to Nov 7, about 208 days.
Is the soil safe to grow vegetables in Hubbard?
The federal record around Hubbard is a meaningful one — 438 documented sites, mostly Underground Storage Tanks entries (258), the nearest Underground Storage Tanks record under a tenth of a mile 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 Hubbard?
From about Oct 22 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 21 (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 21. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
Everything above is measured at Hubbard's scale — its 9a band and its 243-day season. Your yard writes its own version of Hubbard's numbers: we read soil, sun, drainage and frost at your exact address. Try it for 14 days — no card required.
