In fact, Korea’s first president, Rhee, was noted to have said that Japan only said the flowers came from Japan because Korea was a colony of Japan during that time. Indeed, research has been published verifying that the Washington cherry blossoms are closely linked with the Jeju flower variety. Still, there are arguments that the Jeju flowers are just one of many species.
Cherry trees need temperate climates in order to survive. Places that have warm and sunny days with cool nights and frequent rainfall are ideal growing areas, but the seedlings are flexible enough to tolerate partial sun or shady locations. The plants grow in sandy, loamy or clay soil as long as the soil drains well and is kept moist.
Cherry trees are not considered endangered, but just as with any plant, pests and tree diseases and fungi can deteriorate their health. Cold snaps also affect cherry blossoms. The cold weather doesn’t necessarily damage the tree itself, but the flowers in peak bloom can die.
