Cherry blossoms originated in China. According to the authoritative Japanese book "The Great Construction of Cherry Blossoms", cherry blossoms originated in the Himalayas. After artificial cultivation, this species was gradually introduced into the Yangtze River valley in China, southwest China and Taiwan Province Island. During the Qin and Han dynasties, cherry blossoms were planted by the royal family of the court for more than 2,000 years. During the Han and Tang Dynasties, it was widely planted in private gardens. During the heyday of the Tang Dynasty, all countries came to North China, and Japan deeply admired the glory of Korean culture. The planting technology of horticultural flowers was brought back to Japan by Tang envoys along with architecture, costumes, tea ceremony and kendo.

According to literature research, cherry blossoms were planted in the court of China during the Qin and Han Dynasties more than two thousand years ago. Cherry blossoms have generally appeared in private courtyards in the Tang Dynasty. Bai Juyi said in a poem: "I also know that the official residence is not my home, and the courtyard is full of cherry blossoms." Recently, I took the exam five times, but I have to look at the flowers at least four times. " There is also "a new cherry tree planted in the small garden, which makes it easy to swim around the flowers." This poem clearly shows that the poet dug up wild mountain cherry blossoms from Shan Ye and planted them in the yard for viewing. Cherry blossoms are mentioned in Yu Ruoying's poems in the Ming Dynasty: "The rain is thin in March, and cherry blossoms are suspected of apricot blossoms." In the Compendium of Materia Medica written by Tang Meng, the definition of cherry is: "This is a cherry, not a peach. Although it is not a peach, it is called a cherry because of its shape. " The explanation of the name of Sakura Mountain is: "The common name of this Sakura is Li Tao, and the former Sakura is not a peach."

In the Song Dynasty, Linggeng of Chengdu County truly described the main characteristics of early cherry blossoms, leaving valuable evidence for future generations. He said in "Fu of Bitter Cherry Blossoms": "I am short of Chengdu County, and the official residence is Fangzhai East, and there are cherry trees: there are big and small, and their ripeness is bright red and lovely. Its bitterness is inedible, although the birds also abandon it. " Here he describes the real size, and the bitter ones that can't be eaten must be cherry blossoms.

In the Southern Song Dynasty, Wang Sengda wrote a poem: "When cherry blossoms first move, they are bright and burn flowers. The leaves haven't opened yet, and the safflower is already shining. " As can be seen from the poem, this kind of cherry blossom is a red early flowering variety with pale yellow leaves and gorgeous flowers.

"Compendium of Materia Medica" written by Li Shizhen in Ming Dynasty said: "Although this book is small and big, it is sweet and delicious" and it is a cherry. Moreover, according to what he said, "it is easy to fall into water", it can be concluded that this is clearly a cherry blossom that blooms early, with its branches hanging down.

Textual research on the name of Wu plants in Qing Dynasty: "Begonia, born in Yunnan Mountain ... blooms in early winter, with long and round petals, and a green heart stands out among many stamens, which is different from Haitang and cherry blossoms. The spring knot is red and round, the size is like a finger, and the constant acid is inedible. " Begonia this winter is the cherry blossom in winter. Now there are many other places in southern Yunnan, such as Shiping, Jianshui and Yuanjiang. Locals still call it "winter begonia". From all kinds of literature

According to the records, many kinds of cherry blossoms, such as Chimonanthus praecox, Prunus mume, Begonia and Plum Blossom, have been introduced and cultivated in China since ancient times. Japanese cherry blossoms have been planted for more than 1000 years, more than 1000 years later than China.

Because Japanese cherry blossoms are so famous that they have cultivated the best varieties in the world, cherry blossoms refer to Japanese cherry blossoms or cherry blossom varieties with Japanese characteristics to some extent. After the introduction of horticultural breeding technology into Japan, the varieties of cherry blossoms have been increasing under careful cultivation, becoming a rich cherry blossom family. After becoming the national flower of Japan, it has been nurtured and cultivated, and there are more ornamental varieties.

However, some cherry blossoms originated in the Himalayas still grow in Japan, such as Joe and Fei. Yunnan Cherry Blossom and Japanese Cherry Blossom evolved from the original bitter cherries in Tengchong and Longling, and they are one variety. Flowers change from single to double, and the color changes from light pink to dark pink. This color is different from Japanese cherry blossoms, which are also highly ornamental. The flowers of Japanese cherry blossoms are mostly light pink.
