Chasmanthium latifolium is a rhizomatous, clump-forming cool-season grass. Clusters of linear, pointy basal leaves sprout in late fall and overwinter close to the ground until spring when they sprout into arching blades of grass. Taller stalks topped with loose panicles of tiny flowers emerge in late spring. Flowers are very tiny and hard to see with the naked eye, but are followed by and ovoid mass of flat, ‘oat-like’ seeds that sway in the breeze on the drooping stalk by late summer. Spreads by rhizomes and tolerates occasional flooding.
