Description

Schizachyrium scoparium is a tuft forming, perennial bunchgrass with short rhizomes and solid, slightly flattened culms that grow to 1 m in height. The leaf bluish colored blades are folded and sometimes rolled under, smooth to hair, especially near the collar, 4-30 cm long and up to 4 mm wide. The usually hairless sheath has a keel and the membranous ligule is fringed and < 2.5 mm long. The flowering culms are many branched, each terminating in a single spicate straight to undulating raceme, 2-6 cm long, the rachis and pedicels hairy. The copper colored spikelets occur in pairs, one sessile and perfect with bracts (glumes) 6-9 mm long, the other pedicellate and usually staminate with glumes 3-6 mm long. Little bluestem blooms from July into October on prairies throughout South Dakota.

Additional Notes

Little bluestem is a striking bunchgrass that adds year-round color and texture to a native plant garden. The leaves are greenish to very blue and turn yellow to copper to red in the fall and winter, depending upon the seed source. Many cultivated selections are available. This species can adapt to a wide range of conditions and is drought tolerant. They attract many species of butterflies, bumblebees and birds.
