Fanwort(Cabomba caroliniana) is a submerged perennial native to the southeastern United States and parts of South America. It typically grows in 3-10 feet (1-3m) of water and prefers acidic lakes, ponds and quiet streams. At high densities it forms extremely dense stands, clogging water flow and impairing recreational activities. The opposite leaves are fan-like and are attached to the stem on petioles. Small white flowers bloom in late summer. Reproduction and local spread can occur through short rhizomes and seeds. In late summer the plant becomes fragile and breaks apart very easily, facilitating long distance spread within a waterbody.
