Davidia

The Dove tree, Davidia involucrata, is a medium-sized deciduous tree, usually included in the tupelo family Nyssaceae, but sometimes included (with the tupelos) in the dogwood family Cornaceae, and by others given a family of its own, the Davidiaceae. It is native to central China (from Hubei to southern Gansu, south to Guizhou, Sichuan and Yunnan).

Dove tree flowers

It is the only member of its genus, but there are two varieties differing slightly in their leaves, Davidia involucrata var. involucrata, which has the leaves thinly pubescent (short-haired) on the underside, and Davidia involucrata var. vilmoriniana, with glabrous (hairless) leaves.

It is a moderately fast-growing tree up to about 20-25 m tall, with alternate cordate leaves resembling those of a linden in appearance, except symmetrical, not with the lop-sided base typical of linden leaves; the leaves are mostly 10-20 cm long and 7-15 cm wide.

Young Dove tree in flower

The Dove tree is best known for its flowers. These form a tight cluster about 1-2 cm across, reddish in colour, each flowerhead with a pair of large (12-25 cm), pure white bracts at the base (performing the function of petals in other plants). These hang in long rows beneath the level branches. The flowers are at their best in late May. On a breezy day, the flowers flutter in the wind like white doves, hence the English name of the 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, pendulous on a 10 cm stalk. The nut contains 3-6 seeds.

The genus Davidia is named after Father Armand David (1826-1900), ("Père David"), a French Franciscan missionary and keen naturalist in China, who is also commemorated in the Chinese white pine Pinus armandii and Père David's Deer.

The species was introduced from China to Europe and North America in 1904, and is a popular ornamental tree in larger gardens. Most trees in cultivation are var. vilmoriniana, which has proved much better able to adapt to the climatic conditions in Europe and North America. The photos here were taken at Tatton Park gardens in Cheshire, England.
