Couch grasses (Elymus)

Couch grasses

Also known as: Wildryes

Couch grasses are tall grasses that are sometimes considered invasive garden weeds due to their creeping underground stems that grow rapidly and take over beds, borders, and lawns. They grow in almost all soil types and thrive in gardens, roadsides, and cultivated lands. In addition to serving as a cover crop and soil stabilizer, they are also used as feed for livestock and a lawn beautifier.
