Also called English ryegrass, perennial ryegrass is a cool-season bunchgrass native to Europe, Asia and North Africa but distributed around the world. Perennial ryegrass can tolerate high traffic, so it is often planted outside of schools, homes, parks and other high-traffic areas making lawn care and upkeep less burdensome. Perennial ryegrass can be identified by its fine texture, the leaf folded in the bud, parallel leaf margins and a bunchgrass-type growth habit.
