Brookhurst, Wyoming, sits in USDA hardiness zone 5a — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
On paper, cabbage, cranberry, lavender, and collard greens all suit these conditions — on the ground, soil, sun, and drainage make the final call.

What this means for growing in Brookhurst
Each reading below is measured for Brookhurst itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
MeasuredBrookhurst runs about 156 days between hard freezes — a moderate growing season.
There is room for the full run of cool-season crops plus a warm-season main crop, but the calendar is tight enough that a late spring or early fall frost still decides how much finishes.
Time warm-season transplants to your last hard freeze, and a few weeks of season extension turns a near-miss harvest into a sure one.

Winter hardiness
MeasuredBrookhurst 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 Brookhurst is in
Brookhurst sits in the Northwestern Great Plains — EPA Level III, inside the wider Great Plains. That is read at Brookhurst's own centroid, and it is not what its county reads: Natrona County is mostly Wyoming Basin. The wider page above you is answering a different question about different ground.

Is it too late to plant in Brookhurst?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Apr 7; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near May 5 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Oct 8 — long-season crops need about 90 days of runway, quick greens only 30. Late in the year the fall bench takes over — quick greens, radishes, and garlic that repays you next summer.

Your land is one point inside Brookhurst
Everything above resolves to Brookhurst as a whole — one PHZM band and one 28°F frost record, read across 419 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 Brookhurst
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 Brookhurst’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 Brookhurst
When does frost risk typically end in Brookhurst?
The last hard freeze (28°F) in Brookhurst typically lands around May 5, 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 May 26.
When is the first frost in Brookhurst?
The first hard freeze (28°F) in Brookhurst typically arrives around Oct 8, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Sep 24, so the watching starts about Sep 8 — about 156 days after the spring freeze cleared.
How long is the growing season in Brookhurst?
Measured between 28°F hard freezes, Brookhurst sees about 156 frost-free days — roughly May 5 through Oct 8, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer May 26 to Sep 24, about 121 days.
Is the soil safe to grow vegetables in Brookhurst?
The federal record around Brookhurst is a meaningful one — 731 documented sites, mostly Underground Storage Tanks entries (420), the nearest Superfund 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 Brookhurst?
From about Sep 8 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 8 (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 8. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
