Special care should be given to controlling its spread, as it can become invasive if not managed properly. Regular trimming helps maintain its shape and prevent overgrowth, making it a suitable choice for low-maintenance gardening.

Blue wild rye is a common species of wild rye native across the United States. Its blue-green blades grow in small bunches up to 1.5 m tall. It is valuable for erosion control and reforestation projects.
As a guideline ears appear in early summer and spikes with no pattern are arranged on the ears and the ears are slightly flat and elongated and well-developed buds are facing upwards. However there are many approximate species. The stalk grows up slightly to the side at the base and rises to 40 to 100 cm. The leaves are 20 to 30 cm long and 5 to 10 mm wide emerging from the stem nodes green and not shiny. The flowering period is from spring to summer and the ears rise from the tip of the stem and rise to a bow. A spike-like inflorescence with a small spike along the stem. The spikelet is upward along the axis and the length is 1.5 to 2.5 cm. It is slightly flat and long and contains 5-10 florets. The color is green and white as if powdered and it is usually purple. The cocoon that extends from the tip of the pallet is 1.5 to 3 cm long and many are purple. The cocoon grows smoothly toward the tip of the ear and does not warp when dried.
Elymus canadensis is a species of wild rye that's native to North America. It's widely found in the central part of the continent and the Great Plains. The plant can grow in several different habitats, like woodlands, dunes, prairies and areas that have been disturbed. Canada Wildrye is often used to stabilize eroded areas as well as for vegetating metal-rich soils.
Quack grass (Elymus repens) spreads quickly using creeping rhizomes. This has led to its use as a forage crop and erosion control plant in many places outside its native habitat. In some countries, including the USA, it has proved to spread too quickly, and is now classed as an invasive that crowds out native species.
Hairy wild rye (Elymus villosus) is a native grass of the eastern USA. It favors damp woodlands and small meadows. The flowers are insignificant and wind-pollinated, so do not attract insects. Birds seldom eat the seeds, and the plant is not palatable to wildlife. Livestock eat the foliage, but the bristles on the seed heads can injure their mouths and intestines.
