The High Plains spans USDA hardiness zones 4b-8b — a band that supports both cool-season staples and warm-season crops chosen to fit the local frost window.
A semi-arid shortgrass tableland of deep soils and big sky, where wind, low rainfall, and irrigation shape dryland wheat, sorghum, and resilient gardens. Crops well matched to these conditions include colorado blue spruce, tomato, penstemon, and apple — though what thrives on any one site still turns on its specific soil, sun, and drainage.
The High Plains spans Colorado, Kansas, Nebraska, New Mexico, Oklahoma, Texas and Wyoming. Its footprint follows the EPA Level III ecoregion boundary; the counties linked below are representative of the region, not an exhaustive list.
