Spanish jasmine, or Jasminum grandiflorum, is one of the most fragrant of the jasmine plants. Primrose jasmine, or Jasminum mesnyi, is another very fragrant plant in the jasmine family. The star jasmine is considered one of the most fragrant plants, but it is actually not a jasmine plant at all.
The genus Jasminum includes in excess of 30 plants in the Oleaceae group. This large family of plants originates from warm regions in Europe, Africa and Southeast Asia, where it has been grown for millennia. Jasmine is commonly used in various blends of teas for its aromatic fragrance and sweet flavor.
