Prunus japonica (also Cerasus japonica), also called Japanese bush cherry,[1] Oriental bush cherry, or Korean bush cherry is a shrub species in the genus Prunus that is widely cultivated for ornamental use.

Its native range extends from Central China through to the Korean peninsula.

The shrub reaches 1.5 m by 1.5 m. Its flowers are hermaphrodite and are pollinated by insects.

[1] Its fruit reaches about 14 mm and has an agreeably sweet flavor, therefore it is used in making pies, but its taste is quite sour, reminiscent of that of sour cherry.

The plant usually grows from seed but can also be propagated through cutting or layering.
