A cherry blossom is a flower of many trees of genus Prunus. The most well-known species is the Japanese cherry, Prunus serrulata, which is commonly called sakura (桜 or 櫻; さくら).
They are widely distributed, especially in the temperate zone of the Northern Hemisphere including Japan, Taiwan, Korea, Mainland China, Nepal, India, Pakistan, Afghanistan, Iran, Myanmar, Thailand and West Siberia. Along with the chrysanthemum, the cherry blossom is considered the national flower of Japan.
All varieties of cherry blossom trees produce small, unpalatable fruit or edible cherries. Edible cherries generally come from cultivars of the related species Prunus avium and Prunus cerasus. From Wikipedia https://en.wikipedia.org/wiki/Cherry_blossom
