Jasminum sambac
The plant is widely grown for its beauty and fragrance with the flowers used in teas, perfumes and oils. The flower buds can be harvested in the early morning according to size and firmness. It is important to make sure they are white, rather than still green, because the oils responsible for the fragrance are not as well developed. Open buds have already started to lose their oil content and are less fragrant, so many more would be needed to extract the same volume of oil.
