Purple Loosestrife (Lythrum salicaria) is a perennial forb or subshrub known for its distinctive purple flowers and light green foliage. Native to parts of Europe and Asia, it has been introduced to many other regions including North America, where it can be found in moist to wet soils such as along riverbanks and marshes.

Purple Loosestrife is hardy in zones 3-10 and can grow up to 1 meter tall, adding vibrant color to wetland gardens while also providing sustenance through its edible components.
