Prunus apricots, of cherries, and of plums, all of which have cultivars developed for commercial fruit and nut production. The almond is not a true nut, the edible part is the seed. Other species are occasionally cultivated or used for their seed and fruit. A number of species, hybrids, and cultivars are grown as ornamental plants, usually for their profusion of flowers, sometimes for ornamental foliage and shape, and occasionally for their bark.

It is found in Gansu, Guizhou, Hubei, Qinghai, Shaanxi and Sichuan provinces. It is a shrub or tree tall, preferring to grow at above sea level. A genetic and morphological study has shown that it is conspecific with "Prunus persica", the cultivated peach. "P.kansuensis" is being investigated as a source for rootstocks and for crop improvement due to its resistance to multiple diseases, to drought, and to
