Prunus davidiana[4][5][6][3] (syn. Amygdalus davidiana,[1] Persica davidiana,[1][4] Prunus persica var. davidiana)[1] is a species in the genus Prunus in the family Rosaceae. It is also known by the common names David's peach[1][5] and Chinese wild peach.[1] It is native to China, preferring to grow in forests and thickets, on slopes in mountain valleys, and in waste fields, from 800 to 3200 m.[4][5] It is resistant to frost, and to a number of pests and diseases of cultivated peach, and is the subject of many studies for the genetic improvement of peaches.

Description

Deciduous, upright tree.[4][5]

Height and Spread: Reaches a maximum height and spread of 9 m (30 ft) by 9 m (30 ft).[5]
Branches: Young branches whippy, upright,[5] and smooth.[4]
Bark: smooth, dark purplish-red
Leaves: Dark green,[5] glabrous leaves are lanceolate-narrow ovate in shape, ranging in length from 5–12 cm (2–5 in).[4] Leaf point is long and slender, tapering to a point;[4][5] leaf margins finely toothed.[4][5] Petioles are glandular.[4]

P. davidiana var. rubra has deep rosy-colored flowers.[4]

Etymology

Prunus is the ancient Latin name for plum trees. Davidiana is named for L'Abbé Armand David (1826-1900), a missionary and collector of Chinese plants.[7]
