Osmanthus has long been planted in Asian countries other than China because it has variable uses and benefits as worthy flowers. The history of osmanthus goes back to in 1789, an osmanthus specimen was launched to the Kew Gardens, which is located in England as a botanical garden. However, the specimen is from Southern China, so it was unable to survive the cool English climate. In the 18th century, Jean Marie Delavay, who was a French botanist, traveled China. And he explained some kinds of specimens after he brought them back to his country. Among them, there were specimens including osmanthus. In the mid-19th century, Delavay re-introduced osmanthus to European gardeners.
