In 1958, 200 acres on the slopes and basin of Koko Crater at the eastern end of Oahu were set aside as a botanical garden. Although it is still only partially developed, long-range plans envision Koko Crater Botanical Garden as an example of a xeriscape. Here selective planting and water conservation techniques transform this landscape into a garden where plants suitable to these desert-like surroundings can thrive and flourish.
