Davidia involucrata, the dove-tree,handkerchief tree, pocket handkerchief tree, or ghost tree, is a medium-sized deciduous tree in the family Nyssaceae. It was previously included with tupelos in the dogwood family, Cornaceae. It is native to South Central and Southwest China from Hubei to southern Gansu, south to Guizhou, Sichuan and Yunnan, but is widely cultivated elsewhere.
Davidia involucrata is the only member of its genus, but there are two varieties differing slightly in their leaves, D. involucrata var. involucrata, which has the leaves thinly pubescent (short-haired) on the underside, and D. involucrata var. vilmoriniana, with glabrous (hairless) leaves. Some botanists treat them as distinct species, with good reason, as the two taxa have differing chromosome numbers so are unable to produce fertile hybrid offspring.
It is a moderately fast-growing tree, growing to 20–25 m (66–82 ft) in height, with alternate cordate leaves resembling those of a linden in appearance, except that they are symmetrical, and lacking the lop-sided base typical of linden leaves; the leaves are mostly 10–20 cm long and 7–15 cm wide and are ovate to heart-shaped.
Davidia involucrata is best known for its flowers. The Latin specific epithet involucrata means "with a ring of bracts surrounding several flowers". These form a tight cluster about 1–2 cm across, reddish in colour, each flower head with a pair of large (12–25 cm), pure white bracts at the base performing the function of petals. These hang in long rows beneath the level branches. The flowers are at their best in late May. On a breezy day, the bracts flutter in the wind like white doves or pinched handkerchiefs, hence the English names for this tree.
The fruit is a very hard nut about 3 cm long surrounded by a green husk about 4 cm long by 3 cm wide, hanging on a 10 cm stalk. The nut contains 3–6 seeds.
