Shrubs or small trees grown around the world for their attractive leaves or fragrant flowers native to the woodlands of Asia, the Pacific Islands and Southern USA.
Best for cool temperate climates. Possibly worth trying in subtropics.
In the garden, plants need fertile organic rich soils that are well drained in full sun to part shade.
During growth, water frequently and apply a liquid fertiliser twice.
Prune after flowering.
