Prunus tianshanica Prunus tianshanica Prunus tianshanica, the Tianshan cherry, is a species of cherry native to the Tianshan Mountains of Central Asia, preferring to grow at 800-1000m. "Prunus tianshanica" is a shrub reaching . The bark is grey, turning browner with age. The flowers are pink, and the dark red fruits, although small, are high in sugar and pleasant to the taste. It hybridizes naturally with "Prunus cerasifera", and the offspring produce fruit. A phylogenetic reconstruction using twelve chloroplast loci and three nuclear genes of 84 species of "Prunus" shows that "Cerasus" is indisputably a synonym (and subgenus) of "Prunus" and that
