Safety Overview
1.Osmanthus — Overview
Osmanthus fragrans, commonly known as sweet osmanthus or fragrant olive, is a captivating evergreen shrub or small tree belonging to the Oleaceae family, which also includes the olive and jasmine. This resilient plant typically reaches heights of up to 6 meters (20 feet) in cultivation, though some specimens can grow taller. Its foliage consists of dark green, leathery, and distinctly oval-shaped leaves, measuring between 3 to 10 centimeters in length, often exhibiting finely serrated margins.
The shrub's most distinguishing feature is its prolific production of small, exquisitely fragrant, tubular flowers. These blooms, usually white to pale yellow, emerge in dense clusters from late summer through early autumn, filling the air with a sweet, apricot-like aroma. The bark presents as grayish-brown, smooth and unblemished in its youthful stages, gradually developing a rougher, flaky texture with age.
Native to the temperate and subtropical regions of Asia, particularly thriving across a wide expanse of China, Osmanthus fragrans prefers well-drained, fertile soils and moderate climates. Its natural habitat includes woodland margins and slopes, where it benefits from consistent moisture but avoids waterlogging.
Beyond its native range, it is extensively cultivated globally, primarily for its exceptional ornamental value and its highly prized fragrance, which is utilized in perfumery and culinary applications. Taxonomically, its placement within the Oleaceae family highlights its evolutionary kinship with other important medicinal and ornamental species.
