Quercus aliena

[5][4] It is native to East Asian states of Korea, Japan (where it occurs in Honshu, Shikoku, and Kyushu), Taiwan and mainland China (where it occurs in the provinces of Anhui, Gansu, Guangdong, Guangxi, Guizhou, Hebei, Henan, Hubei, Hunan, Jiangsu, Jiangxi, Liaoning, Shaanxi, Shandong, Shanxi, Sichuan, Yunnan, and Zhejiang).

The seeds can be crushed into a powder and used as a soup thickener and for mixing into cereals and breads.

[7] Quercus aliena was introduced to Europe in 1908, but remains rare in cultivation outside of its native area.

[8] The taproot is deep, making older plants difficult to move.

[7] It grows in full sun or partial shade and tolerates strong winds.
