The mission of the NTBG is to enrich life through discovery, scientific research, conservation, and education by perpetuating the survival of plants, ecosystems, and cultural knowledge of tropical regions.
This mission would be achieved through: a network of diverse gardens and preserves in Hawai`i and Florida, each with significant biological, cultural, and historical resources; conservation, research, and reference collections (living, library, and herbarium) assembled through discovery and collaboration; research in botany, ethnobotany, horticulture, conservation biology, and restoration ecology through programs and institutes; educational courses, publications, lectures, and visitor programs; and facilities and infrastructure to conduct this work.
The Juliet Rice Wichman Botanical Research Center building, named after the conservationist and botanist, was constructed in 2003 under Dean Sakamoto of concrete to survive hurricanes.
Garden sites are: Thousands of species have been gathered from throughout the tropical world, through hundreds of field expeditions by staff and through collaborations with other institutions and researchers.
Its living collections include the largest assemblages of native Hawaiian plant species and of breadfruit cultivars in existence.
