Grass family (Poaceae)

Summary
7
Elymus repens is an aggressive, cool-season, perennial grass that is native to Eurasia. E. repens spreads by both seeds and rhizomes, and its long running rootstocks extend through the soil and send up numerous shoots, forming a loose but tough sod. Although it has been used for forage and erosion control, this grass now has a wide distribution and is one of the most difficult weeds to control in cultivated fields. [source: Invasipedia]
