While there are many naturally occurring cherry trees in existence, the Okame cherry tree is not one of them. Instead, this variety is a hybrid cultivar created to exhibit incredible ornamental qualities, including its impressive blooms. The Okame cherry tree cultivar comes from the Prunus incisa tree and the Prunus campanulata tree. Traits from both of these parent species have allowed the Okame cherry tree to be both beautiful and relatively resilient to extreme temperatures.
