big bluestem
Andropogon gerardiAlso known as Tall Bluestem, Bluejoint, Turkeyfoot
Dominating the central tallgrass prairies of North America, big bluestem produces distinctive three-branched seed heads that resemble a turkey foot. Deep fibrous roots extend up to twelve feet underground, allowing the grass to survive severe droughts and stabilize soil against erosion. During autumn, its bluish-green summer stems transform into rich bronze and purple hues that persist through winter.
