Big Bluestem grass

Andropogon gerardii Vitman

Family:     Poaceae (Grass family)

Duration:  Perennial

Height:     up to 275 cm (up to 9 ft)

Blooming: Aug.-Sept.


Comments: As a warm season grass, it spends its summer growing then flowering in late summer, early fall.​  It is an important species for foraging in the tall grass prairies of North America. Big bluestem has also been called turkeyfoot grass due to its inflorescence appearance of a turkey's foot.

Etymology: The epithet, gerardii, is in recognition for the botanist, Louis Gérard, who published the seminal, Flora Gallo-Provincialis.  The genus Andropogon comes from the two Greek words andros meaning, "man", and -pogon meaning, "beard".


Landscape: big bluestem is a great edge or accent grass that provides a showy summer and autumn color, unique inflorescence, and size.  This brilliant grass adds bronze, brown, purple, red, and blue color hints into your landscape.  Prevents soil erosion as well.
