The world’s most expensive perfume is produced from the sweet smelling delicate flowers of the Osmanthus. Called Sweet olive/Fragrant Olive or kinmokusei in Japanese. Scientific name: Oleaceae fragrans var. aurantiacus. The flowers smell great and are a golden colour. However, there’s a lighter yellow or whiter version called gin-mokusei.
