Quackgrass · Elymus repens (L.) Gould · (aka couchgrass) is a perennial grass that originated in Europe. It reproduces through rhizomes and seeds.
It grows in moist areas of pastures, lawns, gardens, meadows,
roadsides, ditches, and cultivated fields. Quackgrass furnishes fair
forage for livestock. It can be used for hay, but it may rapidly spread
and become a serious weed. Deer, pronghorn, and small mammals utilize
its forage. Prairie chickens and wild turkeys eat quackgrass seeds.
Quackgrass is an aggressive weed that quickly crowds out more
desirable plants Broken segments of rhizomes can form new plants making
mechanical control impractical.
