Annual ryegrass is often sold as the major component of some very low priced grass seed. It will die out during the winter so forms a lawn that lasts for a single season. Rough bluegrass is often found in shady grass mixes. It has a light green color and does not blend well with other lawn type grasses. It does however do well in moist, shaded sites.
Tall fescue is one of the two worst lawn weeds.
Yet seed is available in most stores. The grass blades of a clump of tall fescue always seem to stay taller than the rest of the lawn. There is no selective control for this grass as the chemicals that kill tall fescue also kill other lawn grasses. Pure stands of this wear tolerant grass are often used on playgrounds or roadsides. Zoysia is a warm season grass that turns brown early in the fall and stays brown until late into the spring.
