Osmanthus fragrans var. aurantiacus f. thunbergii

[Overview]
An evergreen small tree 4–10 m tall, found in forests in warm regions.
Young branches are hairless and grayish.
Leaves are simple and opposite, oblong, 9–15 cm long, leathery, with entire margins or fine teeth.
There are male plants and plants bearing bisexual flowers.
Several flowers grow in clusters in the leaf axils and bloom in September–October.
The corolla is yellowish white, 4-lobed, and fragrant.
The flowers of male plants have 2 stamens and a degenerate pistil.
The fruit is an oblong drupe, ripening purplish black.

[Cultivation]
Propagate by cuttings.
Avoid poor or dry ground, and plant in fertile, well-drained soil.
It tolerates shade, but it becomes leggy and prone to insects, so it is best planted in a sunny place.
It is sensitive to air pollution such as exhaust gas, so it may not flower in places with polluted air.
It is weak against sea wind, so it is not suited to places exposed to sea breezes.
