Purple loosestrife

Aquatic Invasive Species
Lythrum salicaria

  • Purple loosestrife is a tall, flowering plant native to Europe that has invaded many North American wetlands and every watershed in Michigan.
  • Thick stands of purple loosestrife block access to water, overtake native wetland plants and reduce food and habitat for wildlife.
  • Management of purple loosestrife using biological control is beginning to reduce the invasive plant in some areas of Michigan.
