Purple loosestrife (Lythrum salicaria L.) is an invasive, emergent, perennial plant, native to Europe and Asia. It was brought to North America in the early 1800s through a number of pathways including ship ballast, imported livestock, bedding and feed, sheep fleece, as seed for gardens and for use in beekeeping. Since its introduction to North America, purple loosestrife has made its way to nearly every Canadian province (territories excluded) and almost every U.S. state. However, it is most heavily concentrated in northeastern North America.
