Annual ryegrass is primarily used for pastures and quick cover in erosion control plantings. In the South, it is used as a winter annual for overseeding warm season grasses.
Annual ryegrass is quite similar to perennial ryegrass except it is an annual or biennial, depending on climate and/or length or growing season. It may grow a little taller than perennial ryegrass, from 2 to 3 feet tall. Annual ryegrass is a bunchgrass, with numerous long, narrow, stiff leaves near the base of the plant. The under surfaces of leaves are bright, glossy and smooth. Inflorescence stems are nearly naked. There are approximately 227,000 seeds per pound.
