Tallgrass prairies, meadows, open woodlands, and roadsides.

When to Find It

Ecological Role

Provides critical cover and nesting habitat for grassland birds and small mammals, serves as a larval host for several butterfly species, and its deep root systems help build rich prairie soils and prevent erosion.

Easily Confused With

Observation Tips

Look for tall, dense stands in unmanaged or restored prairie areas, especially during late summer and autumn when the seed heads are fully formed.
