Often called the Garden Isle, it’s no secret that Kaua’i is home to a diverse spectrum of flora. The verdant landscape glows in emerald, teeming with lush tropical botanicals. Kaua’i is home to three out of five of National Tropical Botanical Gardens in the U.S. Their team of botanists are dedicated to preserving tropical plant diversity and reducing plant extinction through exploration, propagation, habitat restoration, scientific research, and education.

The McBryde Garden in Poipu boasts the largest collection of native Hawaiian plants in existence. Most of these plants are endemic (occurring only in Hawai‘i), and many are threatened, endangered, or even extinct in the wild.

Invasive Species Control
Preservation of native plant habitats has become so important that the island has resorted to unusual methods of weed and invasive species control. Because the island’s favorable climate also allows invasive species to proliferate, elimination of these non-native species is a priority for endemic flora preservation.
At the Makauwahi Cave Reserve in Poipu, three giant African spurred tortoises serve as weed eaters, helping to keep invasive species in check. The tortoises are credited for aiding the survival of over 5,000 different native plants.
