Quackgrass is best known as a troublesome weed grass. It spreads both by creeping rootstocks and seed. It is believed native to Europe but is now established over most temperate regions of the world. It grows aggressively and seeds abundantly, and is persistent in both cultivated and abandoned fields. Stems grow up to 3 feet. Leaf blades are thin, flat, up to 6 inches long and less than half an inch wide, and sparsely pubescent on the upper surface. It has good forage qualities and is useful for pasture, hay and silage. It may be harvested from volunteer established areas but is not planted agriculturally.
