Andropogon ternarius Michx.
Poaceae (Grass Family)
USDA Symbol: ante2
This is a 1 1/2 ft. bunchgrass which can reach 4 ft. in height. Ribbon-like leaves are often purplish and the silvery-white seed tufts are borne in yellow bracts along the stem. Mature plants are 6-12 in. in diameter. Split-beard bluestem is a perennial.
Frequently found growing with Little Bluestem (Schizachyrium scoparium) in southeastern areas with well-drained sandy or gravelly soil, Splitbeard Bluestem is notable primarily for its silvery white seed tufts, which catch the light and look particularly attractive with the sun behind them.
