Osmanthus Fragrans

Osmanthus fragrans, commonly called sweet osmanthus, is an evergreen shrub or small tree valued for its strongly scented cream to yellow flowers. The small blooms appear in clusters and carry a sweet apricot- or peach-like fragrance. For a managed Australian garden, allow approximately 3–4 m in height and 1–2 m in width, although an unpruned plant may become larger. It suits a fragrant feature planting, hedge, screen, espalier or large container.

Growing in Australia

Australian garden references support a managed size of approximately 3–4 m high and 1–2 m wide, but pruning and growing conditions strongly affect the final dimensions. Choose full sun to partial shade and provide protection from harsh afternoon sun in hotter or dry-summer positions. The plant is evergreen and needs moderate supplementary water, particularly while establishing and during dry weather. Spring and autumn flowering is recorded in South Australia, although timing can vary between regions.

Care tips

Water regularly during establishment, then provide moderate water according to weather and soil. Avoid prolonged waterlogging. Mulch annually to conserve moisture, keeping mulch clear of the trunk. Apply a general fertiliser in spring according to label directions. Prune after flowering to maintain size and shape, avoiding unnecessary heavy pruning of older flowering wood. Monitor for aphids and scale as part of routine garden care.
