Amargosa, Texas, sits in USDA hardiness zone 9b — a zone band wide enough that plant choice, not possibility, is the interesting question.
Among the crops suited to this profile: okra, meyer lemon, california poppy, and artichoke. The site-level story — soil, sun, drainage — decides the rest.
Even in Amargosa, 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 Amargosa 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 Amargosa
Each reading below is measured for Amargosa itself — here is what it means for a garden here, and the move an experienced grower makes about it.

Season length
From county recordsAmargosa runs about 321 days between hard freezes (read from Jim Wells County, the closest normal to Amargosa) — close to year-round growing.
Frost is rarely the limit here; winter plantings are as real as summer ones, and the harder question is which crops shrug off the summer heat.
Grow cool-season crops through the mild winter, and choose heat-tolerant varieties for the summer beds.

Winter hardiness
MeasuredAmargosa sits in USDA hardiness zone 9b.
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 Amargosa is in
Amargosa sits in the Southern Texas Plains — EPA Level III, inside the wider Great Plains. That is read at Amargosa's own centroid, and it is not what its county reads: Jim Wells County is mostly Western Gulf Coastal Plain. The wider page above you is answering a different question about different ground.

Is it too late to plant in Amargosa?
For most of the year, no — what changes is which crops still fit the days remaining. Cool-season crops can go in from around Jan 1; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Jan 27 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 14 — long-season crops need about 90 days of runway, quick greens only 30. Here the calendar nearly circles: cool-season crops take the winter shift, and the next window is always close.

A note from Gnorman
What an experienced grower watches for around here
In and around Amargosa, Underground Storage Tanks runs higher than the national average — 45 sites within ~10 miles of Amargosa. That's not a problem with your land — it's information about it.
Underground Storage Tanks: Underground storage tanks are the single most common source of soil contamination near homes and gardens.
Use raised beds with imported soil — this eliminates the primary soil-contact pathway.

Your land is one point inside Amargosa
Everything above resolves to Amargosa as a whole — one PHZM band, read across 855 acres, with hard-freeze dates borrowed from Jim Wells 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 Amargosa
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 Jim Wells 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 Amargosa
When does frost risk typically end in Amargosa?
The last hard freeze (28°F) in Amargosa typically lands around Jan 27, 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 Feb 17.
When is the first frost in Amargosa?
The first hard freeze (28°F) in Amargosa typically arrives around Dec 14, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 30, so the watching starts about Nov 14 — about 321 days after the spring freeze cleared.
How long is the growing season in Amargosa?
Measured between 28°F hard freezes, Amargosa sees about 321 frost-free days — roughly Jan 27 through Dec 14, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 17 to Nov 30, about 286 days.
Is the soil safe to grow vegetables in Amargosa?
The federal record around Amargosa shows 52 documented sites, mostly Underground Storage Tanks entries (45), the nearest Brownfields record about 1.3 miles out — a typical footprint for a growing area, and proximity to a documented site is information, not a diagnosis of any one yard. It's worth seeing which recorded sites sit closest to where you grow, and testing the soil before new food beds near any of them.
How do I protect my plants from frost in Amargosa?
From about Nov 14 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 Dec 14 (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 Dec 14. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
