In 1958, Koko Crater on the eastern side of O`ahu was set aside for development into a botanical garden.  Plant collections occupy sixty acres of the inner slopes and basin of this 200-acre crater.  

This garden focuses on the cultivation of rare and endangered dryland plants.  Xeriscape concepts are used to transform this dry landscape into a garden where plants suitable to desert-like conditions can flourish.

Highlights:  Hawaiian plants, African & Madagascan plants, Cactus & Succulent garden, Plumeria grove, Dryland palms
