Reed

"Phragmites australis, known as the common reed, is a species of flowering plant in the grass family Poaceae. It is a wetland grass that can grow up to 20 feet (6 metres) tall and has a cosmopolitan distribution worldwide. [...] It is a helophyte (aquatic plant), especially common in alkaline habitats, and it also tolerates brackish water,[4] and so is often found at the upper edges of estuaries and on other wetlands (such as grazing marsh) which are occasionally inundated by the sea. [...] In North America, the status of Phragmites australis is a source of confusion and debate. It is commonly considered a non-native and often invasive species, introduced from Europe in the 1800s.[7] However, there is evidence of the existence of Phragmites as a native plant in North America long before European colonization of the continent.[8] The North American native subspecies, P. a. subsp. americanus (sometimes considered a separate species, P. americanus), is markedly less vigorous than European forms. The expansion of Phragmites in North America is due to the more vigorous, but similar-looking European subsp. australis.[9][7]" -Wikipedia
