About Thladiantha dubia Bunge
Thladiantha dubia, commonly called Manchu tubergourd, goldencreeper, wild potato, and red hailstone, and known as thladianthe douteuse in French, is a herbaceous perennial climbing vine that belongs to the gourd family. This species is native to Russia, northern China, and Korea. It has been introduced to Japan, southeast Europe (specifically Austria, Romania, and Germany), the Galapagos Islands, and scattered locations across North America, including Manitoba, Ontario, Quebec, Connecticut, Illinois, Massachusetts, Minnesota, New Hampshire, New York, and Wisconsin. In North America (the United States and Canada), it is occasionally cultivated as a medicinal plant or an ornamental plant. Like all other members of its genus, Thladiantha dubia is dioecious. It grows from a tuber and spreads vegetatively through underground rhizomes that develop into new tubers.
