A native warm-season grass with distinctive three-pronged seed heads that resemble a turkey foot. It forms upright clumps and turns striking reddish-purple in fall.

Why grow it

Big bluestem offers reliable structure and late-season color in prairie and savanna plantings where cool-season grasses dominate. Compared to other warm-season bunchgrasses like indiangrass or switchgrass, it establishes more slowly but provides distinct visual interest through its characteristic three-pronged inflorescences and burgundy fall foliage. It tolerates a wide range of soil conditions and requires no fertilization once established, making it suitable for low-input perennial plantings across much of eastern North America.

Watch out for

This grass can take two to three years to reach full productivity, so interplanting with faster-establishing species may help fill space during establishment. In extremely wet or poorly drained soils, growth may be stunted or plants may decline, so site selection matters more than most warm-season grasses.
