Purple loosestrife is a worthy opponent.
The weed came to the east coast of the United States, both accidentally and intentionally, in the early 1800's. By 1929, it had made its way to the Puget Sound. Perhaps the heaviest infestation can be found in irrigation waste ways south of Interstate 90 in Grant County. Purple loosestrife spreads along ditches and the banks of streams, ponds and lakes, crowding out cattails and other native wetland vegetation, and threatening wildlife habitat. It also infests irrigation canals and waste ways.
