Brighamia insignis is a member of the bellflower family. This short-lived perennial is extremely rare and is, according to the U.S. Fish and Wildlife Service, one of only two Brighamia species, both of which are endemic to Hawai‘i. There is only one known plant surviving in the wild, growing on the rocky ledges and steep sea cliffs on the island of Kaua‘i.
• There is only one known plant remaining in the wild.
• Utilizing seeds received in 1999 from 13 of the last remaining Brighamia insignis plants in the wild, the University of Hawai‘i at Mānoa’s Harold L. Lyon Arboretum has successfully propagated approximately 50 plants that have since been sent back to the island of Kaua‘i to be used in restoration projects.
The Harold L. Lyon Arboretum is the only university botanical garden in the United States located in a tropical rainforest. Consisting of almost 200 acres in the beautiful valley of Mānoa on the island of O‘ahu, the arboretum is dedicated to the rescue and propagation of rare and endangered native Hawaiian plants. Making its collections and information available to a broad clientele including students, researchers, industry and the general public, the arboretum serves as a center for educational activities on plants, arts, culture, geography and a range of other sciences. Hosting approximately 34,000 visitors annually through participation in tours, classes, research projects and community activities, the facility, located at 3860 Mānoa Road, is open 8 a.m. to 4 p.m., Monday through Friday, and from 9 a.m. to 3 p.m. on Saturday.
