Osmanthus

Osmanthus is a genus of about 30 species of flowering plants in the family Oleaceae. Most of the species are native to eastern Asia (China, Japan, Korea, Southeast Asia, the Himalayas, etc.) with a few species from the Caucasus, New Caledonia, and Sumatra. Osmanthus has been known in China since ancient times with the earliest writings coming from the Warring States period; the book Shanhai Jing: Nanshan Jing (Classic of Mountains and Seas: Classic of the Southern Mountains) states: "The first peak of the Que Mountain range is Mount Zhaoyao, rising by the western sea, where many osmanthus trees grow, and where rich veins of metals and jade lie hidden."

==Description== Osmanthus range in size from shrubs to medium-sized trees, tall. The leaves are opposite, evergreen, and simple, with an entire, serrated or coarsely toothed margin. The flowers are produced in spring, summer or autumn, each flower being about 1 cm long, white, with a four-lobed tubular-based corolla ('petals'). The flowers grow in small panicles, and in several species have a strong fragrance. The fruit is a small (10–15 mm), hard-skinned dark blue to purple drupe containing a single seed.
