Florence, Texas, 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.
Reliable performers under these conditions include cabbage, fig, california poppy, and collard greens; what your own ground favors still comes down to its soil, sun, and drainage.
Even in Florence, 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 Florence 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 Florence
Each reading below is measured for Florence itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Season length
From county recordsFlorence runs about 292 days between hard freezes (read from Williamson County, the closest normal to Florence) — 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
MeasuredFlorence 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.

The kind of country Florence is in
Florence sits in the Cross Timbers — EPA Level III, inside the wider Great Plains. That is read at Florence's own centroid, and it is not what its county reads: Williamson County is mostly Texas Blackland Prairies. The wider page above you is answering a different question about different ground.

Is it too late to plant in Florence?
Almost never — the real question is what to plant next. Cool-season crops can go in from around Jan 16; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Feb 13 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Dec 2 — 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.

A note from Gnorman
What an experienced grower watches for around here
In and around Florence, Toxics Release Inventory runs higher than the national average — 8 sites within ~10 miles of Florence. It's not cause for alarm — it's worth knowing, and there's a sensible way to grow around it.
Toxics Release Inventory: TRI facilities report annual chemical releases to air, water, and land.

Your land is one point inside Florence
Everything above resolves to Florence as a whole — one PHZM band, read across 584 acres, with hard-freeze dates borrowed from Williamson 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 Florence
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 Williamson 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 Florence
When does frost risk typically end in Florence?
The last hard freeze (28°F) in Florence typically lands around Feb 13, 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 Mar 6.
When is the first frost in Florence?
The first hard freeze (28°F) in Florence typically arrives around Dec 2, per NOAA 1991–2020 climate normals — the point tender summer crops finish. Lighter frosts run ahead of it, near Nov 18, so the watching starts about Nov 2 — about 292 days after the spring freeze cleared.
How long is the growing season in Florence?
Measured between 28°F hard freezes, Florence sees about 292 frost-free days — roughly Feb 13 through Dec 2, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 6 to Nov 18, about 257 days.
Is the soil safe to grow vegetables in Florence?
The federal record around Florence shows 31 documented sites, mostly Underground Storage Tanks entries (10), the nearest Underground Storage Tanks record about 0.1 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 Florence?
From about Nov 2 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 2 (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 2. Hardy greens and roots shrug off light frost and sweeten after it — leave them in.
