Poaceae (Grass Family)



Freshwater cord grass or prairie cord grass is a very rigid, upright perennial, 5-6 ft. tall, with tough leaves. Coarse, ascending spikelets of tan-colored seedheads are arranged spirally in two’s on the upper part of the stem and are the main virtue of this grass. Fall color is an attractive yellow. A tall grass, with stiff, widely spaces flowering branches, the entire flower culater reaching well above the leaves.

This is one of our tallest grasses and is probably the species that gave rise to Midwestern settlers’ accounts of grass higher than a horse’s back. Prairie Cordgrass is one of the dominants of the tallgrass prairie, growing mainly in low, wet areas. The species name derives from the Greek word pecten (“comb”), referring to the appearance of the plants flowering branches. Also known as Sloughgrass.
