About
Quercus variabilis, the Chinese cork oak, is a species of oak in the section Quercus sect. Cerris, native to a wide area of eastern Asia in southern, central, and eastern China, Taiwan, Japan, and Korea.
Where it grows
The species can be found in evergreen and deciduous forests below 3,000 m (9,800 ft), in the Chinese provinces of Anhui, Fujian, Gansu, Guangdong, Guangxi, Guizhou, Hebei, Henan, Hubei, Hunan, Jiangsu, Jiangxi, Liaoning, Shaanxi, Shandong, Shanxi, Sichuan, Taiwan, Yunnan, and Zhejiang, as well as in Japan and Korea.
Uses
It is cultivated in China to a small extent for cork production, though its yield is lower than that of the related cork oak. It is also occasionally grown as an ornamental tree. For pharmaceutical grade production of Ganoderma lucidum, known in China as 'the mushroom of immortality,' the dead wood logs of Q. variabilis are used.
