Decodon verticillatus, the sole living species in the genus Decodon, is a flowering plant in the family Lythraceae. It is commonly known as waterwillow or swamp loosestrife. It is native to wetlands in the eastern half of the United States and Canada.
Waterwillow is found in swampland, in ditches, besides streams and in shallow water at the edges of ponds and lakes. It often forms thickets and occurs in the United States from Maine to Florida and west to Minnesota, Tennessee and Louisiana, as well as in eastern Canada.
