Wedged between the foothills of the Appalachian Mountains to the east and the glaciated land to the north and west, no other area of Ohio boasts a richer abundance of plant species.Known as the Bluegrass Region of Ohio, Adams County harbors scattered pockets of prairie communities, a remnant of the past when the great western prairies reached into Ohio. Sometime after the last glacial advance, the climate turned warmer and drier. It was during such periods that the prairie advanced eastward into Ohio. Purple coneflower, little blue stem and prairie dock provide an impressive display during the peak blooming season of mid-summer.
