Cherry blossom cultivation by country
In the present day, ornamental cherry blossom trees are distributed and cultivated worldwide. While flowering cherry trees were historically present in Europe, North America, and China, the practice of cultivating ornamental cherry trees was centered in Japan, and many of the cultivars planted worldwide, such as that of Prunus × yedoensis, have been developed from Japanese hybrids.
