Common cool season grasses include Kentucky bluegrass, perennial ryegrass and fine fescue, and common warm season grasses include Bermuda grass, St. Augustine, zoysiagrass and bahiagrass. Centipede grass and seashore paspalum are also common warm season grasses.
In America, most of the homes in northern areas with cooler climates have lawns consisting of a combination of Kentucky bluegrass, perennial ryegrass and fine fescue grasses. Kentucky bluegrass, the most common type of grass throughout the North and in the transition zone, is a high-maintenance grass that does not tolerate shade or drought. Perennial ryegrass is resistant to wear, and it germinates quickly. Fine fescue tolerates shade and drought well.
Warm season grasses are not usually mixed because they compete for resources. A typical grass type in the southern zone varies depending on the lawn owner's preference and the lawn's soil type. Bermuda grass grows best in full sun, and it is not easily affected by drought. St. Augustine can tolerate high heat, making it an ideal choice in hot southern climates.
Zoysiagrass tolerates heat and drought and is commonly used in the transition zone between the North and the South. Bahiagrass can be grown in many different types of soils, and it is not easily harmed by insects, drought or disease. Centipede grass is easy to maintain and grows in soil that lacks nutrients. Seashore paspalum is ideal for coastal lawns where salt is prevalent.
