Yamabuki is a spring flower which has been celebrated in Japan since ancient times. It is mentioned in the Manyoshu, the oldest anthology of Japanese poetry. The Japanese name "Yamabuki" is said to be derived from "Yamaburi" (meaning "mountain swing”) due to its slender, flexible branches swaying in the wind. According to the legend, a gold coin dropped at the bottom of a valley and turned into a yamabuki flower, becoming a symbol of "good fortune” for Japanese people.
