Osmanthus plants are evergreen shrubs or small trees. The leaves are opposite, usually leathery and toothed. The flowers are small, white or yellow, and highly fragrant. They are produced in clusters in the late summer and autumn. The fruit is a small, hard, and blue-black drupe.

There are about 30 species in the Osmanthus genus. Some of the most well-known include Osmanthus fragrans (sweet osmanthus), Osmanthus heterophyllus (holly osmanthus), and Osmanthus delavayi (Delavay osmanthus).

Uses[edit | edit source]

Osmanthus is widely used in horticulture because of its attractive foliage and fragrant flowers. It is also used in traditional Chinese medicine and in the production of tea, wine, and other beverages. The flowers of Osmanthus fragrans are used to produce a highly prized essential oil known as osmanthus absolute.
