Big Bluestem (Andropogon gerardii)

Big Bluestem (Andropogon gerardii) is a towering, native prairie grass known for its tall, upright growth, blue-green foliage, and striking seasonal color. As a dominant species of North American tallgrass prairies, it provides essential habitat, erosion control, and dramatic vertical interest in naturalistic and sustainable landscapes.

Distinctive Features

Big Bluestem grows 6 to 8 feet tall, forming dense, upright clumps with wide, blue-green leaves that often develop reddish-bronze hues in late summer and brilliant coppery-red tones in fall. Its distinctive seed heads, resembling a turkey’s foot, emerge in late summer, adding unique texture and wildlife value.
