Purple Loosestrife is an invasive alien introduced species in North America, where it has colonised many waterside sites at the expense of native flora. Instead, place them in the municipal green waste, as this is composted on an industrial scale, where tough weeds should be killed off. No individual species were consistently associated with or repelled by the presence of L. salicaria across sites. Introduced into North America in the 19th century, Purple-loosestrife is now an invasive weed, forming impenetrable stands that are unsuitable as cover for native animals and shade out native plants. This is the time of year when swampy areas often are ablaze with gorgeous pink-purple flowers that dominate the wetland. It has become a menace to the native plants where it chokes out the growth of all its competitors. volume 21, pages199–209(2001)Cite this article. Center for Invasive Species and Ecosystem Health.
