Pittosporum undulatum is a tree to 12 metres in its natural habitat but usually smaller in cultivation. It provides dense shade and spreads up to 7 metres across. It has coarse grey bark and glossy green elliptical leaves some 6-15 cm long and 1.5-4 cm wide with distinctive wavy, or undulating margins. The leaves are about 75 mm long with toothed margins. Small, white, fragrant flowers occur in terminal clusters in spring and early summer and are followed by orange-tan berries 1 cm in diameter in autumn, which persist for several months.

The species is well established in cultivation in Australia and some other warm regions around the world such as California. It is a hardy and adaptable plant which appreciates most acidic soils and extra moisture, yet can also withstand extended dry periods once established. It can be clipped into hedges and is quick growing, as well as having pleasantly perfumed flowers which can pervade a large area (hence the common name 'native daphne').
