    Class B noxious weed in Washington, and targeted as one of the top priorities to control. Found in wetlands, where it out-competes native plants, provides a poor habitat for waterfowl, clogs the waterways, and reduces forage. Do not plant in Washington, and if found, remove any plants to reduce the seed source.

    Although of pleasant aspect growing up to 5' tall w/ reddish-purple clustered flowers and a four-sided stem; caution should be used. This loosestrife often occurs in dense stands that shade out native flora and is considered quite invasive (garden or in the wild). Likes to grow along moist edges of marshes, ponds, and roadsides.
    Plant was introduced from Europe to the east coast of America in the early 1800's by immigrants as an ornamental and herb. Plant spread into the Midwest in the 1880's, reaching Illinois in the 1950's.
    Plant is very difficult to eradicate. Each plant produces 1000s of seeds yearly that can lay dormant in soil for years; also replicates from roots and broken stems.
