About
Purple Loosestrife
Purple loosestrife is native to Europe and Asia. After being introduced to North America, it managed to escape the specialized insects and diseases that keep it in check in its native lands. Free from these natural controls, purple loosestrife gained a competitive edge over our native wetland plants. This advantage, along with prolific seed production and a large, hardy growth, has allowed purple loosestrife to invade many of our wetlands to the near total exclusion of most other vegetation;; it literally shades everything else out.
