What is Oshima-zakura

Oshima-zakura (scientific name: Cerasus speciosa) in Japanese (Scientific name: Cerasus speciosa) is a species of deciduous broad-leaved "cherry" tree in the family Rosaceae. It is an island form of the Kasumizakura (Kasumi cherry) and is an early-blooming cherry tree native to the Izu Islands, including Oshima. It is a tall tree, reaching a height of 15 meters. The leaves are elliptic to inverted-ovate and acute, with a leaf blade 5 to 10 cm in length and narrow serrations on the leaf margins. In spring, at the same time as the green leaves emerge, it produces five-petaled flowers with a diameter of 3 to 4 cm and white to light pink petals. The flowering period is long, from January to April. Fruits ripen after flowering and turn red. The leaves are used to wrap sakura mochi (rice cakes), the trees are used as roadside trees and garden trees, and the wood is used for lumber and firewood. The Oshima cherry stock (Oshima-cho, Tokyo) has been designated a natural monument.
