Valle Verde, Texas, sits in USDA hardiness zone 9b — a zone band wide enough that plant choice, not possibility, is the interesting question.
Crops well matched to these conditions include okra, meyer lemon, california poppy, and artichoke — though what thrives on any one site still turns on its specific soil, sun, and drainage.
Even in Valle Verde, 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 Valle Verde 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 Valle Verde
Each reading below is measured for Valle Verde itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsValle Verde runs about 326 days between hard freezes (read from Webb County, the closest normal to Valle Verde) — 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
MeasuredValle Verde 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 Valle Verde is in
Valle Verde sits in the Southern Texas Plains — EPA Level III, inside the wider Great Plains. That is read at Valle Verde's own centroid rather than borrowed from Webb County.

Is it too late to plant in Valle Verde?
Usually not — gardeners here simply switch what goes in the ground as the season moves. 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 25 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 17 — long-season crops need about 90 days of runway, quick greens only 30. In a climate this gentle, “too late” hardly applies — the question becomes which crops prefer the cooler months ahead.

What an experienced grower watches for around here
In and around Valle Verde, Underground Storage Tanks runs higher than the national average — 57 sites within ~10 miles of Valle Verde. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around 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 Valle Verde
Everything above resolves to Valle Verde as a whole — one PHZM band, read across 127 acres, with hard-freeze dates borrowed from Webb 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 Valle Verde
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 Webb 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 Valle Verde
When does frost risk typically end in Valle Verde?
The last hard freeze (28°F) in Valle Verde typically lands around Jan 25, 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 15.
When is the first frost in Valle Verde?
The first hard freeze (28°F) in Valle Verde typically arrives around Dec 17, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Dec 3, so the watching starts about Nov 17 — about 326 days after the spring freeze cleared.
How long is the growing season in Valle Verde?
Measured between 28°F hard freezes, Valle Verde sees about 326 frost-free days — roughly Jan 25 through Dec 17, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Feb 15 to Dec 3, about 291 days.
Is the soil safe to grow vegetables in Valle Verde?
The federal record around Valle Verde shows 59 documented sites, mostly Underground Storage Tanks entries (57), the nearest Nitrate record about 9.0 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 Valle Verde?
From about Nov 17 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 17 (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 17. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
