Spartina alterniflora

            This plant, commonly called “smooth cordgrass,” is a relative of Spartina patens and is native to coastal states along the Atlantic Ocean and the Gulf of Mexico. Like spartina patens, it is considered a harmful invasive species along the Pacific Coast, where it grows quickly and disrupts the growth of native vegetation. In some countries where this grass is damaging to native species, it is illegal to grow or sell the plant. In Eastern and Southern coastal states the plant plays the vital role of stabilizing soil in salt water marshes.
