Perennial grasses are plants that live for more than two years, regrowing each season from their root systems. They are commonly found in various ecosystems, including prairies, savannas, and grasslands. These grasses play a vital role in soil health, preventing erosion and providing habitat for wildlife. Unlike annual grasses, which complete their life cycle in one year, perennial grasses can thrive for many years. They have deep root systems that help them access water and nutrients, making them resilient to drought. Examples of perennial grasses include Bermudagrass, Fescue, and Bluegrass.
