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.
