Davidia involucrata is a deciduous fast growing tree up to 20 m tall, with bark lifting from the trunk in large flakes. It is native to South Central and Southwest China where it is listed as rare. It is the only member of the genus Davidia.
Its has deltoid, green leaves with serrated margins. Young leaves are scented.
D. involucrata flowers form a tight cluster about 1–2 cm across, reddish purple in colour, each flower head with a pair of large (12–30 cm), pure white bracts at the base performing the function of petals. These hang in long rows beneath the level branches. In New Zealand the flowers are at their best in spring. 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.
This 80 year old tree is growing in Tupare Gardens, New Plymouth, Taranaki.
