One of TPP's indoor plants has a tendency to be overlooked when it flowers. In general, it is raised for foliage, and in warmer climates it is often used as a foundation planting particularly the variety with variegated leaves. This is probably Pittosporum tobira, a common variety. This tree is about 16" tall and has a trunk about 2" in diameter. It has been trained as a bonsai tree for about 30 years.
The flowers are about a half inch in diameter and they are highly fragrant with a mock orangish sort of scent, very sweet, thus the common name. A small cluster of flowers appears in every whorl of leaves. You smell the flowers as you come into the room. Too bad we don't have scratch and sniff monitor screens.
