It can be used to feed livestock and some wild herbivores will graze it. It has been shown to survive pollution with crude oil. It can be used in phytoremediation when the soils are high in heavy metals. There are other uses for the grass, including erosion control in sandy coastal areas, its native habitat. 'Seadwarf' is a bright green type that is more resistant to a grass disease called dollar spot than other cultivars. The leaves of 'Salam' are glossy on the undersides, giving the field a striped look when it is mowed. 'Salam', the most common cultivar in Hawaii, is another dark green type suitable for golf courses. The cultivar 'Aloha' is a dark green grass used for golf courses and athletic fields. The best-known and oldest cultivar may be 'Adalayd' a grass with a similar texture and blue-green color to Kentucky bluegrass. For example, fine-textured types are used for golf courses, while coarser grass is selected for roadside revegetation. There are many cultivars bred for various uses. Weeds can be controlled by the application of saltwater, in which weeds will die and the grass will survive. "It has the highest salt tolerance of all turfgrasses." It is also more competitive against weeds than similar grasses. This species has "filled a niche in America", being a better grass to use on turf next to the ocean in places that receive sea spray. The grass will be lower in quality than that irrigated with potable water, but it survives. The grass can even be irrigated with saltwater. It can be irrigated with non-potable water, such as greywater, an important advantage in a time when there are increasing restrictions on water use. The main advantage of this grass is that it is very salt-tolerant. It can grow in lawns that receive rain on 250 days per year, and it can survive being waterlogged or submerged for several days at a time. It forms a higher quality turf than bermudagrass in poor conditions, such as wet soils and low light levels, and with fewer nitrogen soil amendments. This grass has been bred into cultivars which are used for golf course turf and other landscaping projects. The genome of Paspalum vaginatum was sequenced in 2022 and the species' haploid genome was determined to be approximately 590 megabases in size. ![]() In the wild this species grows in salt marshes and brackish marshes. It spreads by its rhizomes and stolons, forming a thick turf. The branches are lined with oval to lance-shaped spikelets which grow pressed against the branches, making the panicle narrow. The panicle is usually a pair of branches up to 7.9 centimetres (3.1 in) long there is sometimes a third branch below the pair. ![]() The leaf blades are 10 to 19 centimetres (3.9 to 7.5 in) long and may be hairless to slightly hairy. The stems grow 10 to 79 centimetres (3.9 to 31.1 in) tall. It is a perennial grass with rhizomes or stolons. It is also cultivated as a turfgrass in many places. It is found throughout the other tropical areas of the world, where it is an introduced species and sometimes an invasive weed. It is native to the Americas, where it grows in tropical and subtropical regions. Paspalum vaginatum is a species of grass known by many names, including seashore paspalum, biscuit grass, saltwater couch, silt grass, and swamp couch. ![]()
