Prunus fenzliana is a species of wild almond native to the Caucasus areas of Turkey, Armenia, Azerbaijan and Iran, preferring to grow at 1400-3500 m above sea level. On the basis of morphology it has been long thought to be one of the wild species that contributed to the origin of the cultivated almond. Genetic testing of both nuclear and chloroplast DNA has confirmed that it is the closest relative of Prunus dulcis.
