Lexington County, in South Carolina, sits in USDA hardiness zone 8b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
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.
Lexington County lies within the Midlands (Columbia) — a regional growing area with its own character.

Lexington County — the short answer
Lexington County, South Carolina: USDA zone 8b, about 265 days between hard freezes, across 447K acres.

Heat and winter chill in Lexington County
Across a year, Lexington County accumulates about 5,306 growing degree days above 50°F, about 158 more than the middle South Carolina county — ahead of 27 of South Carolina’s 46 counties. Degree days are the heat a crop actually gets to work with — more of them is more room to ripen a long-season crop before the freeze closes the window.
Winter banks about 1,267 hours below 45°F, 95 fewer than the South Carolina middle of 1,362. Chill is what tells a fruit tree its dormancy is over, and it is set by climate rather than by anything you can build.

Soil in Lexington County
Across Lexington County, the ground is predominantly Ultisols, where Lakeland, Blaney, and Vaucluse are the most extensive named soil series. The soil is generally well drained with a sand surface. Topsoil pH runs about 5.5, strongly acidic. Rainfall drains through hydrologic group A soils.

How the ground varies across Lexington County
The USDA soil survey maps 46% of Lexington County as well drained — but another 45% drains differently: 27% excessively drained, 6% moderately well drained.
Lakeland is the most extensive named soil at 30% of mapped acres, then Blaney (8%) and Vaucluse (7%).
Which of them your own lot sits on is a parcel question, not a county one. Check your address for the survey at your boundary.
What this means for growing in Lexington County
Each reading below is measured for Lexington County itself — here is what it means for a garden here, and the move an experienced grower makes about it.
Drainage
MeasuredThe dominant soils across Lexington County are well drained, in hydrologic group A — ground that drains quickly.
The upside is soil you can work early in spring and roots that never drown; the cost is that fast-draining ground dries out fast and leaches nutrients away before plants can use them.
Work in compost and mulch to hold moisture and feed, and water more often in short doses than deep and rarely.
USDA NRCS SSURGO
Surface pH
MeasuredTopsoil across Lexington County runs about pH 5.5, on the acidic side.
Blueberries, potatoes, and rhododendrons thrive in it, but most vegetables start locking out nutrients below about pH 6.0 and grow pale and stunted no matter how much you feed them.
A measured lime application raises pH for the crops that need it — but test first, because the right rate depends on your own soil, not the county average.
USDA NRCS SSURGO
Season length
MeasuredLexington County runs about 265 days between hard freezes — 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.
NOAA 1991–2020 Climate Normals
Winter hardiness
MeasuredLexington County 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 Lexington County is in
Lexington County spans 2 EPA Level III ecoregions — Southeastern Plains (73%) and Piedmont (27%). Which one your land falls in changes what grows wild there and how the ground behaves, and a county-wide answer cannot tell you which.
What Grows in Lexington County
We scored all 1,086 plants against Lexington County's own USDA zone 8b and its own 265-day season between hard freezes, using the same matching engine that runs a full parcel report. These cleared both. Sun, soil pH and drainage vary lot by lot — those are the parcel questions below. Each card opens that plant's South Carolina profile.
Is it too late to plant in Lexington County?
Usually not — gardeners here simply switch what goes in the ground as the season moves. Cool-season crops can go in from around Feb 6; tender transplants wait until two to three weeks after the last 28°F hard freeze, which lands near Mar 6 (NOAA 1991–2020 climate normals); and from midsummer, planting counts back from the first fall freeze around Nov 26 — 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 the federal record shows across Lexington County — and how to grow with it.
We checked the federal record across Lexington County — 1,280 documented sites across 7 of the 9 source types we track.
The most significant on record: 12 Superfund sites. Sites tracked in EPA's Superfund program — from assessment-stage CERCLIS entries to confirmed National Priorities List cleanup sites.
Lexington County carries one of the heavier federal records we track — and that's not a verdict on your yard. Proximity to a documented site is information, not a diagnosis: nothing here says any particular parcel is affected. It does earn one concrete step — before food beds go in the ground, a professional soil test tells you exactly what you're working with, and raised beds with clean imported soil grow well almost anywhere in the meantime.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.

Your land is one point inside Lexington County
Everything above resolves to Lexington County as a whole — one PHZM band and one county frost record, read across 447K 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 county 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 county average.

How we know this about Lexington County
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, read at county grain; hard-freeze dates from NOAA 1991–2020 28°F normals at this county’s own record where one resolves, and the labelled statewide window where none does; soils from the USDA NRCS SSURGO survey, area-weighted across the county’s own map units; boundaries and acreage from US Census TIGER/Line 2025; the contamination and pesticide records from the federal sources named in their beats above. Where Lexington County carries no record of its own, the figure is inherited and labelled — the resolution ledger below names each.
Common questions about Lexington County
When does frost risk typically end in Lexington County?
The last hard freeze (28°F) in Lexington County typically lands around Mar 6, 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 27.
How long is the growing season in Lexington County?
Measured between 28°F hard freezes, Lexington County sees about 265 frost-free days — roughly Mar 6 through Nov 26, per NOAA 1991–2020 climate normals. Tender crops work a shorter one: nearer Mar 27 to Nov 12, about 230 days.
Is the soil safe to grow vegetables in Lexington County?
The federal record around Lexington County runs heavier than most — 1,280 documented sites, mostly Underground Storage Tanks entries (729), the nearest Underground Storage Tanks record about 2.3 miles out — so test the soil before planting food in the ground, and raised beds with clean imported soil grow well in the meantime. Even here, proximity to a documented site is information, not a diagnosis of any one yard; the contamination map shows exactly what's recorded and where.
