This is an annual grass from Europe, grown for hay in Oregon and Washington west of the Cascade Mountains. In the Southern States it is grown as a winter annual for pasture, hay, silage and as a cover crop. The plant develops rapidly from seed, making a quick cover suitable for early grazing. It is nutritious and palatable. Many seed sources contain both Italian and perennial seed. See perennial ryegrass.
