Attu Station, Alaska, sits in USDA hardiness zone 8b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
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 Attu Station, no two yards are alike.

Each reading below is measured for Attu Station itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Winter hardiness
MeasuredAttu Station 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.

Your land is one point inside Attu Station
Everything above resolves to Attu Station as a whole — one PHZM band and one 28°F frost record, read across 91K 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 Attu Station
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, with the labelled statewide window where none resolves; 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 Attu Station
When does frost risk typically end in Attu Station?
Attu Station has no hard-freeze normal of its own, so it follows Alaska's statewide window: the middle half of counties see their last spring hard freeze (28°F) around Apr 16 - May 15 and their first fall hard freeze around Sep 24 - Oct 29, per NOAA Regional Climate Centers ACIS (1991–2020). Frost dates shift with elevation and local microclimate, so watch your own site's cold pockets. 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.
Is the soil safe to grow vegetables in Attu Station?
The federal record around Attu Station is light — 1 documented site across the 9 federal source types we checked, mostly Brownfields entries (1), the nearest Brownfields record about 5.1 miles out — 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 Attu Station?
As the season closes around Alaska's statewide first fall hard freeze (28°F) near Sep 24 - Oct 29 (NOAA Regional Climate Centers ACIS (1991–2020)), 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 the first hard night. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
