Plant
Perennial Ryegrass
Lolium perenneAlso known as English Ryegrass, Winter Ryegrass, Ray Grass
Perennial ryegrass forms dense, dark green tufts with hairless leaves that show a distinctive glossy sheen on their undersides and a reddish-purple tint at the base. Its tall, unbranched flowering stems carry flat spikelets pressed edgewise against the central stalk, releasing clouds of wind-borne pollen in late spring and summer. Native to Europe, Asia, and northern Africa, it now anchors pastures, sports fields, lawns, and roadside verges across the temperate world.
