Thinopyrum ponticum (syn. Agropyron elongatum, Elymus elongatus, Elymus obtusiflorus) is a species of grass known by the common names tall wheatgrass,[1] rush wheatgrass, and Eurasian quackgrass. It is native to Eurasia and it has been introduced to many other parts of the world, including much of the Americas and Australia.[2]

This perennial bunchgrass can grow up to 2 meters tall. The ribbed leaves have pale green blades a few millimeters wide. The inflorescence is a spike studded with spikelets up to 3 centimeters long, each containing up to 12 flowers.[3]

This grass is used as a forage and for hay in many places.[4] It is good for land with saline soils, and it can help reduce the salinity. It is also good for non-saline soils.[5] This grass is commonly crossed with its relative, wheat, in order to give the wheat traits such as stress tolerance and pest resistance.[6][7]
