Orange Sweet Olive

Osmanthus fragrans f. aurantiacus

The Story

Plant Bio

Osmanthus fragrans, the sweet olive, is a dense evergreen shrub or small tree prized for its intensely fragrant, small flowers that carry a powerful apricot-like scent. Native to Asia, it features glossy, dark green, opposite leaves and maintains a neat, rounded to oval form in cultivation.

The form 'f. aurantiacus' is distinguished by its vibrant bright orange to apricot-colored flowers that put on a dramatic display in the fall. This variety shares the same exceptional fragrance as the species but offers a distinct, warm color palette that stands out against the dark foliage.

Uses & Benefits:

Valued for its glossy evergreen foliage and highly fragrant, bright orange autumn flowers.

Highly resistant to deer and rabbit browsing, making it a reliable choice for open landscapes.

Attracts general pollinators with its nectar-rich flowers and offers dense cover for nesting birds.

Planting

How to Grow

Select a planting site with well-drained soil in full sun to partial shade, providing afternoon shade in hot southern climates.
Dig a hole twice as wide as the root ball and of equal depth, ensuring the top of the root ball sits slightly above the surrounding soil level.
Backfill with native soil, tamp down gently to remove air pockets, and water deeply to settle the root system.
Apply a 2- to 3-inch layer of organic mulch around the base, keeping it a few inches away from the main stem to prevent rot.

Pro Tip

Prune lightly immediately after the primary fall or spring flush; cutting back into old, leafless wood results in poor recovery and patchy regrowth.

Keep It Thriving

Care Guide

Do

Water regularly during dry spells to maintain soil moisture while the root system establishes.
Apply a balanced, slow-release evergreen fertilizer once annually in early spring.
Provide afternoon shade in hot southern climates to prevent foliage scorch.

Don't

Do not plant in poorly drained, waterlogged soils, which quickly leads to root rot.
Avoid heavy annual pruning, as flower buds form on old wood.
Never shear the plant into old, leafless wood.
