What is National Tropical Botanical Garden?

The National Tropical Botanical Garden is a group of botanical gardens and preserves focused on tropical plants. Its sites, mainly in Hawaii and one in Florida, feature living collections of thousands of species, including rare and native Hawaiian plants and a wide range of breadfruit varieties. Visitors can explore gardens such as McBryde, Allerton, Limahuli, Kahanu, and The Kampong, each with unique plant displays and landscapes. The preserves, which are not open to the public, serve as refuges for endangered species and as research areas for scientists.

The history of National Tropical Botanical Garden

The idea for a tropical botanical garden in the United States began in the early 1960s, when a group sought support from Congress. In 1964, a law was passed to establish what was first called the Pacific Tropical Botanical Garden, later renamed the National Tropical Botanical Garden. Its main office is in Kalāheo, Kauaʻi, and the organization is a nonprofit with a congressional charter. Over the years, it has expanded to include several gardens and preserves across Hawaii and Florida, collecting plants from tropical regions worldwide.

What there is to see

Each garden within the NTBG network is designed to showcase tropical plants in natural or landscaped settings. The gardens are open to visitors for tours, while the preserves are protected areas for plant conservation and research. The Breadfruit Institute, part of NTBG, focuses on conserving breadfruit varieties and studying their uses. The gardens and research centers are built to withstand local weather, including hurricanes.

When to go

The gardens welcome visitors for tours and educational activities, offering a chance to see rare and diverse tropical plants up close. Scientists use the preserves to study plant conservation and to reintroduce endangered species. The Breadfruit Institute works to promote breadfruit as a food and for reforestation. The NTBG also provides courses, lectures, and publications for the public and researchers.

NTBG manages several gardens, each with its own focus. McBryde Garden and Allerton Garden are on Kauaʻi, Limahuli Garden and Preserve is also on Kauaʻi, Kahanu Garden is on Maui, and The Kampong is in Florida. The preserves, such as Lawai, Ka'upulehu, Awini, Kahanu, and Limahuli, are dedicated to protecting native habitats and are not open to visitors.
