Thladiantha dubia, the Manchu tubergourd,[1] goldencreeper, wild potato, or (French) thladianthe douteuse, is a herbaceous perennial climbing vine of the gourd family.

[2] It is native to Russia, northern China, and Korea, but has been introduced to Japan,[2] southeast Europe (Austria, Romania, Germany),[citation needed] the Galapagos Islands, and scattered locations in North America (Manitoba, Ontario, Quebec, Connecticut, Illinois, Massachusetts, Minnesota, New Hampshire, New York, Wisconsin).

[3][4][5] It is occasionally grown as a medicinal plant, or as an ornamental in North America (the US and Canada).

Like other members of the genus, it is dioecious.

[6] It grows from a tuber and spreads vegetatively by sending out underground rhizomes that produce new tubers.
