The Piedmont spans USDA hardiness zones 7a-8b — room for a real mix of vegetables, fruit, and perennials matched to the local frost calendar.
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.) On paper, pecan, muscadine grape, okra, and collard greens all suit these conditions — on the ground, soil, sun, and drainage make the final call.
The Piedmont spans Alabama, Georgia, North Carolina, South Carolina and Virginia. Its footprint follows the EPA Level III ecoregion boundary; the counties linked below are representative of the region, not an exhaustive list.
