Lirioendron chinense, the Chinese tulip tree, is Asia's native species in the Liriodendron genus. This native of central and southern China grows in the provinces of Anhui, Guangxi, Jiangsu, Guizhou, Hubei, Hunan, Jiangxi, Shaanxi, Zhejiang, Sichuan and Yunnan, and also locally in northern Vietnam. It is very similar to the American species, Liriodendron tulipifera, differing in the often slightly larger and more deeply-lobed leaves, and in the shorter inner tepals in the flowers, which lack the orange pigment of L. tulipifera. The Chinese tulip tree reaches about 40 m tall. It is not as hardy as the American species, but is cultivated in England (where there are many at Kew Gardens), Ireland, Belgium, the Netherlands, and Germany. In North America, it grows as far north as Boston, Massachusetts in the east, and Vancouver, Canada in the west. In cultivation it grows as fast as the American tulip tree.
