Prunus davidiana

Prunus davidiana[4][5][6][2] (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.
