The wetlands of western Canada are facing a serious threat – damage caused by the spread of an invasive plant, purple loosestrife.

In the wild, purple loosestrife, also commonly known as lythrum, invades habitat along rivers, streams, lakes, ditches and wetlands. It creates a dense purple landscape that competes with native plants and deters wildlife.  It is a non-native species introduced from Europe to North America, however, it was not introduced along with its natural predators.  Due to this lack of natural control and the plant’s hardiness, purple loosestrife has spread into natural areas throughout North America. 

Purple loosestrife plants in gardens are capable of causing the spread of purple loosestrife into natural areas through its seeds. To help stop this noxious weed, you are encouraged to remove and destroy existing plants.

Preventing the further spread and controlling existing populations of purple loosestrife is the goal of the Manitoba Purple Loosestrife Project.
