Saint Augustine grass

St. Augustine is a dark green grass with broad, flat blades. It spreads by aboveground stolons, commonly known as "runners", and forms a dense layer. The grass occurs on both sides of the Atlantic Ocean, including much of the southeastern United States, Texas, Mexico, and Central and South America. It has escaped cultivation in California, Hawaii, many Pacific islands, South Africa and New Zealand. St. Augustine grass occurs in most Caribbean and Mediterranean areas. It grows best in tropical climates. It is often seen in lagoons and marshes, on shorelines, and wherever there is a good amount of moisture.

St. Augustine grass is commonly used in pastures and on ranches. It is a popular lawn grass, rivalling bermudagrass, though St. Augustine is somewhat less drought-tolerant.

Only recently has commercially valuable and viable seed for St. Augustine become available, so it has typically been propagated by plugs, sprigs, or sod. Once the grass is cultivated, it can propagate on its own. St. Augustine can grow in a wide range of soil types with a pH between 5.0 and 8.5. It usually blooms in spring and summer.
