The Mississippi Delta spans USDA hardiness zones 7a-10a — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
The flat, deep, dark alluvial bottomland of the lower Mississippi River — extraordinarily fertile cotton, soybean, rice, and sweet-potato ground. Well-matched crops include tomato, peach, muscadine grape, and sweet potato, and the gap between "grows in the area" and "grows in your yard" is closed by soil, sun, and drainage.
The Mississippi Delta spans Arkansas, Louisiana, Mississippi, Missouri and Tennessee. Its footprint follows the EPA Level III ecoregion boundary; the counties linked below are representative of the region, not an exhaustive list.
