Compared to finer textured grasses like the bermudas, St. Augustine has large flat stems and broad coarse leaves. It has an attractive blue-green color and forms a deep, fairly dense turf. It spreads by long above-ground runners or stolons. While it is aggressive, it is easily controlled around borders. It produces only a few viable seed and is commonly planted by sod, sprigs, or plugs. St. Augustinegrass is a big thatch producer, more so than other types of grass. It also requires plenty of moisture and is best suited to humid regions.
