The indiangrass (Sorghastrum nutans) belongs to Poaceae (the Grass family). It is a perennial herb that is native to the central and eastern United States and Canada. This herb grows specially in the Great Plains and tallgrass prairies, and can reach 1-2 m in height. The leaves are linear, 5-60 cm long and up to 1.2 cm wide, mostly flat, and rough textured on both surfaces. They are distinguished by a "rifle-sight" ligule where the leaf blade attaches to the leaf sheath. It blooms from late summer to early fall, and producing panicles. The spikelets are golden-brown during the blooming period, and each contain one floret that has three large, showy yellow stamens and two feather-like stigmas. The fall color of this grass is deep orange to purple.
