Pittosporum ralphii is a hardy North Island evergreen shrub that will handle coastal conditions. It grows to 6m in height and a spread up to 5 m. Naturally occurring only in the north island. It grows between latitudes 37° 30' south and 40°south in the Central North Island, East Cape, and along the Wanganui and the Patea rivers in Taranaki, Hawkes Bay, Rangitikei. Manawatu, Manawatu Gorge and Pahiatua. Its habitat is lowland to lower montane forest margins and streamsides. It is abundant on cliffs and gorges from 0 to 900m altitude. It is now widely cultivated throughout New Zealand.
The leaves of P. ralphii are thick & leathery ( 12.5cm long and 5cm wide) with their lower surfaces densely clad with white tomentum. The leaves usually have an undulating margin. It is similar to P. crassifolium but has a rounded habit and larger, darker-green leaves.
