The Gansu peach (Prunus kansuensis) belongs to Rosaceae (the Rose family). It is a small deciduous tree that is distributed in north-central and south-central China. It grows in mountainous areas at an altitude of 1000 to 2300 m and reaches a height of 3 to 7 m. The leaves are ovate-lanceolate to lanceolate with a narrow tip and sparse serrations on the margins. From March to April, before the leaves unfold, white or pinkish flowers bloom. The calyx tube is bell-shaped. The fruit is a nearly spherical drupe, about 2 cm in diameter, which ripens to a yellowish color from August to September. In China, it is used as rootstock for cultivated peaches and almonds, and is also cultivated for ornamental purposes. In Chinese, it is called "甘粛桃" (gansu tao) in Chinese.
