Wisteria sinensis (Chinese wisteria) is a woody, deciduous, perennial climbing vine in the genus Wisteria, native to China in the provinces of Guangxi, Guizhou, Hebei, Henan, Hubei, Shaanxi, and Yunnan. While this plant is a climbing vine, it can be trained into a tree-like shape, usually with a wavy trunk and a flattened top. Weinheim is a town in the north west of the state of Baden-Wurttemberg in Germany with 43 000 inhabitants, approximately 15 km north of Heidelberg and 10 km northeast of Mannheim. Together with these cities, it makes up the Rhine-Neckar triangle. It has the nickname "Zwei-Burgen-Stadt", or Two-Castle city, named after the two fortresses on the hill overlooking the town in the east on the edge of the Odenwald, the Windeck and the Wachenburg.
