Carpetgrass Stenotaphrum secundatum

St. Augustinegrass is a spreading turfgrass that is native to the southeastern U.S.A., as well as South America and Africa. Originating along the coasts of the Atlantic Ocean, it can be found along sandy beaches, swamp and lagoons edges, island streams, lakes, marshes and along roadsides. 

It is commonly used as pasture grass and also grown as a lawn. This plant is heat tolerant and mildly drought tolerant. There are many cultivars of this plant available. This plant spreads by rhizomes and, if used as lawn grass, will rarely need mowing. It is sold by turf or plugs and is rarely propagated by seed.

Its dense, tight structure makes it resistant to weed infestation. It's known to improve soil structure, enhance water infiltration rates and also increases the soils' water retention capacity. It can also be used as a ground cover under trees to promote soil conservation. When placed on slopes, it will serve as a form of erosion control.  

Grown as a lawn, it will grow in most soils that are found in the southern states. It has a high shade tolerance, making it a better choice than other southern grasses. Typically grown in full sun, it will tolerate full shade and semi-shaded locations.
