213 TALLGRASS SILHOUETTE
Audubon Spring Creek Prairie, Lancaster County, Nebraska. Big Bluestem is one of the dominant grasses of the tallgrass prairie. In April, it begins its growth and after flowering late in the summer, its stem base turns a blue-purple as it matures with its seed head turning a purple-red color in the fall. It grows to be about eight feet in height and its solid root system extends six to eight feet beneath the ground. The seed heads have three spike-like projections and the grass is thus often called "Turkey Foot" or "Turkey Claw."
