Spartina, commonly known as cordgrass or cord-grass,[3] is a genus of plants in the grass family, frequently found in coastal salt marshes.[4]
The genus name is derived from σπαρτίνη (spartiné), the Greek word for a cord made from Spanish broom (Spartium junceum).[5] They are native to the coasts of the Atlantic Ocean in western and southern Europe, northwest and southern Africa, the Americas and the southern Atlantic Ocean islands; one or two species also occur on the North American Pacific Ocean coast and in freshwater habitats inland in the Americas. The highest species diversity is on the east coasts of North and South America, particularly Florida.
They form large, often dense colonies, particularly on coastal salt marshes, and grow quickly. The species vary in size from 0.3–2 m tall. Many of the species will produce hybrids if they come into contact.

Cultivation
Spartina has been planted by humans to reclaim estuarine areas for stripping, to supply fodder for livestock, and to prevent erosion. Various members of the genus (especially Spartina alterniflora and its derivatives, Spartina anglica and Spartina × townsendii) have spread outside of their native boundaries and become invasive.
Big Cordgrass (S. cynosuroides) is used in the construction of bull's eye targets for sports archery. A properly constructed Spartina target can stop an arrow safely without damage to the arrowhead as it lodges in the target.[9]
Ecology
Spartina species are used as food plants by the larvae of some Lepidoptera species including Aaron's Skipper (which feeds exclusively on Smooth Cordgrass) and Engrailed.
As an invasive species
Three of the Spartina species have become invasive plants in some countries. In British Columbia, Spartina anglica, also known as English Cordgrass, is an aggressive, aquatic alien that invades mud flats, salt marshes and beaches, out-competing native plants, spreading quickly over mud flats and leaving large Spartina meadows.[10]
