Lolium sp.

Annual Ryegrass, Winter Ryegrass, Winter Rye

About This Plant

Not recommended. A cool-season grass used as a turf cover crop in high-traffic areas like golf courses, ballfields, and some ranches. It is occasionally used in residential lawns; it works best with warm-season turf that goes dormant in winter, like Bermudagrass or zoysia (but NOT St. Augustine grass.) Ryegrass germinates and grows quickly, providing green color during the cool season, when warm-season turf grasses are brown. Ryegrass dies out naturally after reseeding in spring. In a wet spring it may persist into April or May, competing with the underlying Bermudagrass or zoysia.

Origins: Southern Europe


Watering to establish in November and (depending on conditions) as needed to keep it green. Regular mowing will be required in winter, since it grows quickly; set the blades at 2 to 2.5 inches.
