Prairie Cordgrass, Spartina pectinata
Or sloughgrass, is common in the poorly drained soils or wet prairies and prairie marshes. Prairie Cordgrass has tough thick stems which is reflective of the name and the coarse leaf blades can be quite sharp. Each stem has a long cluster (spike) of branches which holds the individual flower spikelet. This plant spreads agressively by rhizomes and turns golden-yellow in the fall.
