About
Prunus speciosa, the Oshima cherry (Japanese: オオシマザクラ, Hepburn: ōshimazakura), is a true cherry tree noted for its ornamental cherry blossoms. It is native to Izu Ōshima island and the Izu Peninsula on Honshū near Tokyo, Japan.
How to grow it
The Oshima cherry is widely cultivated as an ornamental tree. Because of its large, showy flowers it is planted in many gardens and parks. It prefers sun and moist but well draining soil.
There are many cultivars. It is also a hybrid parent of many of the sakura flowering cherry cultivars. Among these cultivars, those that originated from Oshima cherry are called Cerasus Sato-zakura Group, and many cultivars have a large number of petals, and the representative cultivar is Prunus lannesiana ‘Kanzan’ or ‘Sekiyama’. The reason for this is that Oshima cherry tend to mutate into double-flowered, grow fast, have many large flowers, and have a strong fragrance, so they have been favored for cherry blossom viewing because of their characteristics. When the population of the southern Kanto region increased during the medieval Kamakura period, Oshima cherry, which was originally from Izu Ōshima Island, was brought to Honshu and started to be cultivated there, and then brought to the capital, Kyoto.
