This shrub is called naupaka and is a common "beach" and landscape plant grown typically near the shore as it is salt and drought tolerant. However, it can be grown anywhere in the lowlands where the climate is dry to mesic. Related, are the several endemic naupaka kuahiwi that grow in the mountains. An unusual feature of the flowers in this family are that they are strongly irregular, appearing as half a blossom. The fruit a small white globe.

A popular legend speaks to a couple, much in love but, she a princess (Naupaka) and he a commoner, their union forbidden. In sadness, she gave him half the flower she was wearing and remained in the mountains (kuahiwi) while he, a fisherman, returned to his village near the shore (kahakai). From then on, the naupaka plants bloom with only half a blossom as a sign of the couples unrequeted, but never-ending love (aloha mae ‘ole).
