A cherry blossom is the flower of any of several trees of genus Prunus, particularly the Japanese Cherry, Prunus serrulata, which is sometimes called sakura after the Japanese (桜 or 櫻; さくら). 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.
