Eastern Corn Belt Plains

The Eastern Corn Belt Plains cover the glaciated farm country of western Ohio and eastern Indiana, centered on Columbus, Dayton, Indianapolis, and Fort Wayne. Flat to gently rolling ground, heavy glacial till, and a high water table make drainage the dominant question in most yards here. Natives such as prairie milkweed, glade-mallow, and clustered mountain-mint are prairie and wet-prairie plants that take the clay and the standing water of a wet spring.

Conditions: Heavy glacial till over a high water table, 36–42 inches of rain, cold winters and warm humid summers, slow drainage.

Cities and areas: Columbus, Dayton, Indianapolis, Fort Wayne, Springfield, Muncie.
