A long-lived perennial, 'olulu is a succulent plant adapted to growing in the salty environments of sea cliffs (6). Flowers bloom in September and October, and the small green capsule fruit ripens six to eight weeks after pollination (5). Scientists believe that moths have historically been the natural pollinator of Brighamia flowers, a hypothesis supported by the fact that the nectar of 'olulu is sucrose-dominated and characteristic of flowers pollinated by hawk moths (Lepidoptera sphingidae) (7). The disappearance of this natural pollinator has potentially been a significant contributor to the decline in number of 'olulu plants found in the wild (7).
