Osmanthus fragrans, Fragrant Tea Olive, is one of the most popular gardens plants in China because of the fragrance of its tiny flowers.  It blooms from autumn to spring, and because it is in bloom in mid-autumn, at the time of the moon festival, it has long been associated with lunar legends.  To the Chinese the image visible in the full moon is an osmanthus bush (Valder, 1999).
Osmanthus: from Greek osme, fragrance, and anthos, flowers.
