Propagation cultivation of the species of horticultural varieties, to heavy pink varieties for the best, its seeds are very few, with branch cuttings rooting and very difficult, so the reproduction coefficient is small, limiting its application in the garden. Previous research in improving the reproduction coefficient of Japanese late cherry blossom have not made a breakthrough. The reason why cuttings of Prunus spp. are difficult to root may be related to the accumulation of inert substances in dormant branches. In order to explore the suitable method for the propagation of Japanese evening primrose, non-test tube fast propagation technique was used for fast propagation.

In Japan, the horticultural classification of cherry blossoms is to collectively refer to the wild species as "Yamazakura", and the artificially selected and naturally mutated ones as "Satozakura". At present, China's garden common cherry blossom varieties are:

Cherry blossoms have a history of more than 1,000 years in Japan. In the Nara period (710-794), when it comes to flowers, it means plum blossoms, but in the Heian period (794-1192), cherry blossoms became the main character, and songs about cherry blossoms were five times more than songs about plum blossoms. Cherry blossom viewing has been practiced in Japan since the early 7th century, when Emperor Jotunori was particularly fond of cherry blossoms and visited Yoshinoyama in Nara many times to see them. In addition, it is said that the first cherry blossom viewing event in Japanese history was held in the 9th century under the auspices of Emperor Saga. Cherry blossom viewing was only popular among the powerful and wealthy, but it was not until the Edo period (1603-1867) that it spread to the common people and became a traditional folk custom.

Cherry blossoms have a short life. In Japan, there is a proverb that says: "Cherry blossoms last for 7 days", which means that a cherry blossom lasts about 7 days from opening to fading, and the whole cherry tree lasts about 16 days from blossom to full blossom, which makes cherry blossoms fall as they bloom. It is this characteristic that makes cherry blossoms so attractive. It is honored as the national flower not only because of its charm and delicacy, but also because of its "magnificent" withering after a short period of splendor.
