About NTBG

Perpetuating tropical plants, ecosystems, and cultural heritage since 1964

National Tropical Botanical Garden (NTBG) is a nonprofit with a vision to restore flourishing relationships between plants, people, and places.

We work across a network of botanical gardens, preserves, and research centers in Hawaiʻi and Florida to grow a brighter tomorrow for plants and all they sustain. We do so through a biocultural approach, where Indigenous knowledge, community priorities, and scientific research guide our path forward.

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 combat plant extinction.

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.
