Big Bluestem

Andropogon gerardi

Also known as Turkeyfoot, Tall Bluestem, Bluejoint

Big bluestem reigns as the undisputed monarch of the tallgrass prairie, anchoring native grasslands with an extensive root network that penetrates up to three meters deep into the earth. Foliage emerges with a distinctive bluish-green cast in late spring before transforming into rich shades of copper, amber, and deep maroon after the first autumn frost. Its terminal seedheads split cleanly into three radiating spikes, creating a silhouette so characteristic that early prairie settlers termed it turkeyfoot.

Responsible observation
  • Identifying Seedheads: Look for the three-branched terminal flower clusters resembling a wild turkey's foot.
  • Seasonal Timing: Visit tallgrass prairies in late August to October when flowering stems reach their full height.
  • Prairie Conservation: Stick to designated boardwalks or trails to avoid trampling delicate prairie sod.
