Cherry blossom

The cherry blossom, or sakura, is the flower of trees in ''Prunus'' subgenus ''Cerasus''. ''Sakura'' usually refers to flowers of ornamental cherry trees, such as cultivars of ''Prunus serrulata'', not trees grown for their fruit (although these also have blossoms). Cherry blossoms have been described as having a vanilla-like smell, which is mainly attributed to coumarin.

Wild species of cherry tree are widely distributed, mainly in the Northern Hemisphere. They are common in East Asia, especially in Japan, where they have been cultivated, producing many varieties.

Most of the ornamental cherry trees planted in parks and other places for viewing are cultivars developed for ornamental purposes from various wild species. In order to create a cultivar suitable for viewing, a wild species with characteristics suitable for viewing is needed. ''Prunus speciosa'' (Oshima cherry), which is endemic to Japan, produces many large flowers, is fragrant, easily mutates into double flowers and grows rapidly. As a result, various cultivars, known as the ''Cerasus'' Sato-zakura Group, have been produced since the 14th century and continue to contribute greatly to the development of hanami (flower viewing) culture. From the modern period, cultivars are mainly propagated by grafting, which quickly produces cherry trees with the same genetic characteristics as the original individuals, and which are excellent to look at.

The Japanese word sakura ( or ; or ) can mean either the tree or its flowers (see ). The cherry blossom is considered the national flower of Japan, and is central to the custom of hanami.

Sakura trees are often called Japanese cherry in English. (This is also a common name for ''Prunus serrulata''.) The cultivation of ornamental cherry trees began to spread in Europe and the United States in the early 20th century, particularly after Japan presented trees to the United States as a token of friendship in 1912. British plant collector Collingwood Ingram conducted important studies of Japanese cherry trees after the First World War. Provided by Wikipedia
