rdf:langString Sagittaria platyphylla, the delta arrowhead, broad-leaf arrowhead or delta duck-potato, is a plant species native to the eastern United States. The core of its range extends from central Texas to the Florida Panhandle north to southern Illinois. As an ornamental it has also been spread to other locations. Isolated populations have been reported from Washington state, Missouri, Kansas, Ohio, Kentucky, Pennsylvania, West Virginia, eastern Virginia, North and South Carolina and eastern Georgia, Nuevo León, Michoacán and Panamá. It has also become a noxious weed in Australia. On August 6, 2015 S. platyphylla was found for the first time in China, specifically in the Yangtze River Basin. This detection was in an irrigation ditch in , Wuhan, Hubei, PRC. Other detections have continued through at least 2019 demonstrating its establishment in provinces of the and lower Yangtze. It presents a significant threat to the ecology and economy of the Yangtze area, especially to agricultural irrigation.
