Alternanthera is a genus of about 80 herbaceous plants from the Amaranth family (Amaranthaceae). A few are aquatic plants.
They are cosmopolitan, growing in tropical America and Australia. They are mostly spreading or crawling stoloniferous plants with soft stems, sometimes used as ground cover. The leaves are simple and verticillate. The small white or yellow flowers are arranged in chafflike bracts, growing in the leaf buds.
Alligator weed (Alternanthera philoxeroides), a native of South America, forms dense, sprawling mats, reaching 15 m across. It is considered a noxious weed, choking ponds, lakes, streams, canals, and irrigation ditches. It is being suppressed through biological control with the alligator weed flea beetle (Agasicles hygrophila), the alligator weed thrip (Amynothrips andersoni), and the alligator weed stem borer (Vogtia malloi). Mechanical and chemical controls fail.
