Kahanu Garden offers a unique journey into Hawaiian ethnobotany and ancient culture.
Kahanu Garden offers a unique journey into Hawaiian ethnobotany and ancient culture. This remarkable botanical garden, part of the National Tropical Botanical Garden, is a living museum dedicated to the rich relationship between people and plants of the Pacific. It stands out not only for its botanical collections but also as the home of Piʻilanihale Heiau, the largest ancient temple structure in Polynesia, making it a profoundly significant cultural site.
Visitors can explore the world's largest collection of breadfruit (ʻulu) cultivars, featuring over 150 varieties, alongside the Canoe Garden, which showcases plants brought to Hawaiʻi by early Polynesian voyagers, such as kalo (taro), ʻuala (sweet potato), and maiʻa (banana). The garden also preserves one of Hawaiʻi's last undisturbed hala (Pandanus tectorius) forests and maintains important collections of native Hawaiian plants. These diverse collections provide a tangible link to the agricultural practices and plant resources essential for survival in ancient Hawaiʻi.
A visit to Kahanu Garden provides a serene and educational experience, allowing guests to step back in time and appreciate the deep cultural roots of the Hawaiian people. The dramatic coastal views, combined with the botanical wonders and the awe-inspiring Piʻilanihale Heiau, create a memorable outing. It’s a place where history, culture, and nature intertwine, offering a unique perspective on Hawaii's heritage and the vital role of plant conservation. Eager to name that creature?

The land where Kahanu Garden now thrives holds a deep history, dating back to 1848 when King Kamehameha III granted the 464-acre property to Chief Kahanu. Over the years, the area underwent significant changes, transforming from a sugar plantation in the 1860s to cattle pastures after 1946. In 1974, a pivotal moment occurred when descendants of Chief Kahanu, along with Hāna Ranch, deeded 61 acres to the National Tropical Botanical Garden (NTBG). This agreement stipulated that NTBG would restore Piʻilanihale Heiau, share it with the public, and ensure perpetual care for this sacred site and the family graves located on the land. The garden has since expanded to 293 acres, later cited as 484 acres, and continues its mission of biocultural conservation in the Pacific, with its core being the Piʻilanihale Heiau, which began construction around the 13th century and was registered as a National Historic Landmark in 1964.
