|Stenotaphrum secundatum subsp. var.||Buffalo grass, Grama, St Augustine grass|
St. Augustine grass (Stenotaphrum secundatum) (also known as Charleston Grass in South Carolina) is a warm season lawn grass that is popular for use in tropical and subtropical regions. It is a low to medium maintenance grass that forms a thick, carpetlike lawn, crowding out most weeds and other grasses.
St. Augustine is a dark green grass with broad, flat blades. It spreads by above ground stolons and forms a dense layer of grass.
St. Augustine grass is one type of grass that commonly exists in most Caribbean and Mediterranean areas. It breeds best in tropical climates. It is often seen in lagoons, marshes, shorelines and wherever there is a good amount of moisture.
It is native to both sides of the Atlantic ocean, including much of the southeastern United States, Mexico, and Central and South America. It has escaped cultivation in California, many Pacific islands, and New Zealand.
St. Augustine can grow in a wide range of soil types with 5.0 to 8.5 pH. St. Augustine grasses will be in full bloom between springtime and summer.
St. Augustine grasses are popularly used in pastures and ranches. They are also a popular grass covers for home lawns. It rivals the reputation of Bermuda grass, although St. Augustine grasses are somewhat less drought tolerant.
St Augustine grass produces runners that allow it to grow and spread.
Only recently has commercially valuable viable seed for St. Augustine become available, so it has typically been propagated by plugs, sprigs, or sod. Once the grasses are cultivated, then they can propagate on their own.
