Lepidium latifolium, known by several common names including perennial pepperweed, broadleaved pepperweed, pepperwort, peppergrass, dittander, dittany, and tall whitetop,
Invasive plant
The plant is most invasive in wetland habitats, including riparian zones; from there it easily spreads to other ecosystems, such as sagebrush. It is also a pest in the Monte Vista and Alamosa National Wildlife Refuges in Colorado and Malheur National Wildlife Refuge in Oregon, and many other sites.
The dried stems are sometimes used in flower arrangements.
