Osmanthus americanus: Devilwood

Edward F. Gilman and Dennis G. Watson


A native to the southeastern United States, Devilwood is a very attractive, small evergreen tree which is most commonly seen at 15 to 25 feet in height and sports lush, dark, olive green leaves throughout the year. It is occasionally seen 30 to 40 feet tall in its native habitat and grows slowly. The clusters of small, white, fragrant, early springtime flowers are followed by the production of small, dark blue drupes, ripening in fall and persisting on the tree until the following spring, if not first consumed by birds and other wildlife. Its ease of growth, pest-resistance, attractive foliage and flowers, and wildlife-attracting fruits would make Devilwood a popular choice for naturalizing or the mixed shrubbery border. The trees tolerate heavy pruning particularly well and may also be used as a hedge. Devilwood is so-named because the fine-textured wood is difficult to split and hard to work.

Use and Management

Naturally found along streambanks or swamp margins, Devilwood should be grown in full sun or partial shade on moist, well-drained soil. Drought tolerance is moderate once established. The tree is probably as shade tolerant as any osmanthus. Not tested as an urban tree but may have some merit in wet soils.

Propagation is by cuttings or seed, and is difficult by either.

Pests and Diseases

No pests or diseases are of major concern.
