The Koko Crater Botanical Garden was established in 1958 as a distinct part of the Honolulu Botanical Gardens. The crater itself, locally known as Kohelepelepe, is an ancient volcanic cinder cone formed approximately 40,000 to 50,000 years ago during Oahu's last volcanic events. The garden's mission focuses on the cultivation and conservation of rare and endangered dryland plants, utilizing the crater's naturally hot and arid conditions. In 1966, the **Charles M. Wills Cactus Garden** was officially recognized, acknowledging significant contributions to the garden's development.
