Sometimes nondescript trees draw your attention because they smell so good. One of the most fragrant of this kind is the Lady of the Night, Cestrum nocturnum, which visually presents itself as an Orange-Tree-size, much branching, very dense bush or small tree with leaves and flowers like those shown below:
Lady of the Night's fruits are pea-sized, occur in small clusters, and are white. The tree is native to the Yucatan and is much planted in the tropics worldwide. In India and elsewhere in South Asia its flowers are used in perfumery, for medicinal applications and in religious ceremonies, though some parts of the plant are poisonous.
