CommentsPrairie Cordgrass has attractive foliage with a succulent appearance. It was the dominant grass of wet prairies in Illinois and no other grass species in the state resembles it. There are similar Spartina spp. (Cordgrasses) in brackish and saltwater marshes along both the Eastern and Gulf coasts, but they don't occur in Illinois. Prairie Cordgrass can be distinguished from these species by the long awns of its second glumes (about 1/32/3" in length) and the relative length of its first glumes, which are about the same length as the lemmas (1/3" in length). Other Cordgrasses lack these long awns and their first glumes are shorter than their lemmas.
