(Oenanthe javanica)
Perennial pepperweed is a highly invasive herbaceous perennial. It can invade a wide range of habitats including riparian areas, wetlands, marshes, and floodplains. It adapts readily to natural and disturbed wetlands. As it establishes and expands, the plants create large monospecific stands that displace native plants and animals.
Pepperweed probably entered the U.S. prior to 1940 in a shipment of beet seed (Beta vulgaris) from Europe.
