A cherry blossom is the flower of any of several trees of genus Prunus, particularly the Japanese Cherry, Prunus serrulata, which is called sakura after the Japanese (桜 or 櫻; さくら). Cherry blossom is speculated to be native to the Himalayas. Currently it is widely distributed, especially in the temperate zone of the Northern Hemisphere such as: Europe, West Siberia, South Korea, China, Japan, United States, etc. Many of the varieties that have been cultivated for ornamental use do not produce fruit. Edible cherries generally come from cultivars of the related species Prunus avium and Prunus cerasus.
