The Dove tree (Davidia involucrata), also called handkerchief tree, is a small deciduous tree native to China. The tree was first introduced in the West in 1904 when seeds were sent to a nursery in England. It has a short trunk and a very distinct reddish-gray bark. Toothed, broad, oval bright green leaves (3-6 in long) on red stalks are heart-shaped at the base and resemble the leaves of a linden tree. The tree has small, reddish-purple flower heads are surrounded by a pair of large white bracts up to 30 cm long resembling dangling handkerchiefs or dove wings. The flowers reach their peak in late May. In Latin the tree is named after Father Armand David, who lived in China from 1862 to 1874 and was the first westerner in China to describe the tree, in 1868. Father Armand was also the first person outside of China to describe the giant panda.
