Notes	Quackgrass is an erect, sod-forming perennial that grows from long yellowish-white rhizomes. It is a plant of waste places and sometimes in cultivated fields. The leaves are up to 3/8" wide (10mm), flat or u-shaped and from 4 to 8" long with a twist near the tip. The lower sheath of the leaf is usually hairy. The flower spikelets on the flower spike are upright and tight against the spike. The species name repens means having creeping and rooting stems which refers to the ability of the rhizomes to quickly spread from a point of origin. It is considered quite invasive.
