Invasive plants don't always look like an invasive species. Many are actually quite decorative and viewed as a beautiful addition to your garden. In truth, invasive species are escape artists that threaten native plants and wildlife by destroying habitats needed to sustain them. Prevention is essential to protecting Idaho's natural ecosystems, economy, and even our health. Don't help invasive species flourish by allowing them to establish in your garden.
