However, the abundant intra-cultivar genetic variability usually hampers the application of conventional techniques for cultivar identification. Identification. Annual Ryegrass Basics Annual ryegrass has glossy, rich green leaves that grow up to 12 inches long and is most often used as a forage grass for animals and for hay. In Australia, New Zealand, and a few other countries, L. rigidum, which is known as rigid ryegrass, is also recognized as annual ryegrass. Annual ryegrass (L. rigidum) is one of the most serious and costly weeds of cropping systems in southern Australia, and herbicide resistance is a frequent problem. The species is upright in habit (to about 3 feet in height); seeds germinate in the late fall and the plants grow vigorously through the winter and early spring. Annual ryegrass has gained a reputation for being a favored turfgrass and is even used to overseed home lawns during cold winter months.
