It is native to southern Europe, and it is known in the Americas and Australia as an introduced species and sometimes a noxious weed. An herbicide-resistant strain can be found growing as a weed in canola and wheat fields in Chile.[3] This is an annual grass growing 10 to 50 centimeters tall. The inflorescence is a rounded or oval cluster or series of clusters of spikelets. The fertile spikelet has an awn up to a centimeter long. The awns clumped closely together into a tuft gives the inflorescence its bristly, hairy appearance.
