National Tropical Botanical Garden (NTBG) is a not-for-profit institution, dedicated to discovering, saving, and studying the world’s tropical plants and sharing what is learned.

Our network of five botanical gardens, preserves and research facilities encompasses nearly 2,000 acres with locations in Hawaii and Florida. Thousands of species from throughout the tropical world have been gathered, through field expeditions, collaborations with other institutions and researchers, to form a living collection that is unparalleled anywhere.

Our collection includes the largest assemblages of native Hawaiian plant species and breadfruit cultivars in existence. Many of the species in our collections are threatened and endangered or have disappeared from their native habitats. In our preserves and beyond our gardens, NTBG is working to restore habitats and save plants facing extinction. Our gardens and preserves are living laboratories and classrooms for staff scientists, researchers, students and visitors from all over the world.

National Tropical Botanical Garden is a 501(c)(3) corporation under the regulations of the United States. NTBG’s support comes primarily from donations from individuals and grants from public and private foundations.

Conserving Endangered Flora

Conservation of endangered and threatened flora is our highest priority. NTBG’s Living Collections department collects, curates, grows and outplants propagules from the rarest plants, including species on the Plant Extinction Prevention Program (PEPP) list, which have 50 or fewer individuals remaining in the wild. Learn more about our impact.

The mission of the National Tropical Botanical Garden is to enrich life through discovery, scientific research, conservation, and education by perpetuating the survival of plants, ecosystems, and cultural knowledge of tropical regions. Our mission is 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. Facilities and infrastructure necessary to conduct this work.
