The Pee Dee spans USDA hardiness zones 8a-8b — enough range to grow cool-season vegetables, hardy fruit, and warm-season crops that mature before the first hard frost.
South Carolina's inner Coastal Plain row-crop belt along the Pee Dee River — flat, deep sandy-loam bottomland, Zone 8a–8b, and a long ~261–277-day frost-free season. Distinct from the droughty Carolina Sandhills upslope, the tidal Lowcountry downcoast, and the red-clay Piedmont: this is the state's historic flue-cured (bright-leaf) tobacco heartland, still cotton, soybeans, and truck crops. The conditions favor okra, fig, peach, and muscadine grape, among others — though every individual site edits that list with its own soil, sun, and drainage.

Hardiness Zone Range
What Grows in the Pee Dee
Plants matched to the Pee Dee's USDA zones 8a-8b, ordered by how much hardiness margin each has across the region — the ones with room to spare at both ends of this band lead. Each links to its full growing profile.
Native Plants of the Pee Dee
Plants the USDA PLANTS Database documents as native and present in this region’s state, kept only where the published hardiness range meets the Pee Dee’s USDA zones 8a-8b — closest range match first. Presence is recorded by state, so a plant can be documented across the state and still be scarce in your corner of the region.
The ground across the Pee Dee
The USDA soil survey maps this ground county by county. These are those records weighted by land area across eight member counties — this region’s own profile, not a state figure.
The ground is predominantly Ultisols, at 75% of mapped acres, followed by Inceptisols (12%), Entisols (6%) and Spodosols (4%). Six soil orders appear somewhere inside the footprint, which is the honest reason a regional soil answer only goes so far. The most extensive named soils are Coxville, Norfolk, and Lynchburg.
29% of those acres are poorly drained, and another 23% well drained, 18% moderately well drained. Topsoil pH runs 4.6–5.7 between the lowest and the highest county on record. 30% of the footprint is classed prime farmland.

What this means for growing in the Pee Dee
The soil survey reads this ground county by county, and the readings above are those records summed across the Pee Dee. Here is what they mean for a garden here — and the move an experienced grower makes about each one.
Drainage
From county records29% of the mapped acres across the Pee Dee are poorly drained — ground that sheds water slowly. That is area-weighted across all eight of its mapped counties.
Beds can stay saturated for days after heavy rain, and the roots of most vegetables, berries, and fruit trees suffocate or rot in soil that never drains.
Raised beds or mounded rows lift roots above the wet zone; choose water-tolerant crops for the lowest spots.
USDA NRCS SSURGO
Surface pH
From county recordsTopsoil across the Pee Dee runs pH 4.6–5.7 — acidic in all eight of them.
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.

What the federal record shows across the Pee Dee — and how to grow with it.
Across the Pee Dee's 8 counties the federal record holds 3,674 documented sites, mostly Underground Storage Tanks (2,501), Brownfields (699) and Nitrate (278). The heaviest single county is Horry County, with 1,240.
That is a regional count, not a reading of any one lot — proximity to a documented site is information, not a diagnosis. Open the map outlined to the Pee Dee to see which records sit where you actually grow.

A note from Gnorman
What an experienced grower watches for around here
In and around the Pee Dee, Underground Storage Tanks runs higher than the national average — 2,501 sites across the 8 counties in the Pee Dee. 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.
Sources: EPA, USGS — 1.8M documented sites tracked nationwide across 9 federal source types.
Your land is one point inside the Pee Dee
Everything above resolves to the Pee Dee as a whole — a footprint spanning USDA zones 8a-8b. Your parcel sits in exactly one of them. 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 region 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 regional average.

How we know this about the Pee Dee
The boundary: a cluster of neighboring counties. Growing regions have no official boundary, so this footprint is our published one, and every figure on this page was measured over the counties inside it rather than borrowed from the state around it.
The datasets: hardiness from the USDA ARS Plant Hardiness Zone Map 2023, aggregated across the footprint; the growing season from NOAA Regional Climate Centers ACIS 1991–2020 28°F normals, read at each member’s own record; boundaries from US Census TIGER/Line 2025; the contamination record from the federal sources named in that beat above; the soil from the USDA NRCS SSURGO survey, read at each member county’s own record and weighted to this footprint by land area. Where a member carries no record of its own, it is absent from the figure rather than filled in.
Common questions about the Pee Dee
What hardiness zone is the Pee Dee?
The Pee Dee spans USDA hardiness zones 8a-8b, aggregated from the USDA Agricultural Research Service Plant Hardiness Zone Map 2023 across the region's counties. Zones reflect average annual extreme minimum temperatures from 1991–2020 data.
How long is the growing season in the Pee Dee?
Measured between 28°F hard freezes, the Pee Dee's counties mostly run 262 to 270 frost-free days, median 267 (NOAA Regional Climate Centers ACIS, 1991–2020, over 8 member counties). That 8-day spread is the honest read — no single season describes 8 counties, and each county guide below carries its own.
When does frost risk end in the Pee Dee?
Across the Pee Dee, the middle half of member counties see their last 28°F hard freeze between Mar 5 and Mar 9 (median Mar 6), and their first fall freeze between Nov 26 and Nov 30. Those are hard freezes, not the last light frost: tender transplants wait for about Mar 27, and elevation decides which end of a 4-day spread you garden in.
What grows well in the Pee Dee?
The Pee Dee's conditions suit plants such as Okra, Fig, Peach, Muscadine Grape, Palmetto. What actually thrives on any one site still turns on its specific soil, sun, and drainage — we score each plant against the real conditions at your address.
How is the Pee Dee defined?
The Pee Dee is defined here as a curated cluster of 8 neighboring counties that share a growing character. Growing regions have no official boundary, so this footprint is our published one — every county in it is named on this page.
Which states does the Pee Dee cover?
The Pee Dee spans South Carolina. Each state's full growing guide is linked on this page.
What other growing regions cover the same states?
Piedmont, Tidewater & Chesapeake, Carolina Sandhills, Sea Islands, Lowcountry, and Midlands (Columbia) share at least one state with the Pee Dee. Growing regions overlap and interlock — a single address can sit inside more than one, which is why the precise read is always the parcel, not the region.
What this page reads at the Pee Dee’s own scale
6 of the readings below were taken at the Pee Dee's own scale — the zone 8a-8b band across its footprint, a median 267-day season across its 8 counties and 3,674 documented federal contamination records across its 8 counties, 1,240 of them in Horry County alone; one is borrowed from a wider read, named and linked below.

Other growing regions across South Carolina
The rolling foothill belt between the Appalachians and the coastal plain, defined by heavy red clay soils that reward amendment and drainage. (Southern Piedmont; the Northern Piedmont is a separate ecoregion.)
The low, flat, tidal coastal plain around Chesapeake Bay — sandy soils, mild maritime winters, and a long season for vegetables and Southern staples.
The fall-line band of deep, droughty sand ridges between the Carolinas' Piedmont and Coastal Plain — longleaf-pine and wiregrass country from Chesterfield up through Moore County, with warm zone-8a winters and a roughly 250-day frost-free season.
The barrier-island strip where Georgia and South Carolina meet the Atlantic — a two-state maritime band the mainland Lowcountry page doesn't reach. With ocean and tidal water on nearly every side, the frost-free season runs longer here than inland: a ~302-day median across the region's own coastal counties (vs ~290 for the mainland Lowcountry), stretching past 315 days on the sea islands around Beaufort and Charleston. The footprint is almost uniformly 9a — only inland-edge Colleton dips to 8b. Sandy island soils and salt air shaped a distinct growing tradition: Sea Island cotton, the extra-long-staple crop historically tied to these very islands, and the Gullah-Geechee garden of okra, benne, field peas, and sweet potato.
South Carolina's humid coastal plain of tidal marsh, sandy loam, and long warm seasons — historic rice country, now figs, okra, and Lowcountry truck crops.
The Midlands is central South Carolina's Fall Line core, where the Sandhills grade into the Coastal Plain and Columbia — the hottest major city in the state — sets a genuinely high-heat 8b growing regime. Long, punishing summers make this okra, pepper, and sweet-potato country and stretch the frost-free season to roughly 265-281 days across the 8b core (Richland, Lexington, Orangeburg, Calhoun, Clarendon, Sumter), while the Piedmont-edge north (Fairfield, Newberry) cools to 8a. The heat cuts both ways: what rewards Southern staples also stresses spring tomatoes and bolts cool greens early, so in the Midlands, timing — not just your zone — is what the garden turns on.
