The Honolulu Botanical Gardens are operated by the City and County of Honolulu Parks and Recreation. There are five distinct gardens forming a unique garden system. The five gardens are located in different ecological settings around the island of Oahu. They offer year-round opportunities to explore unique and diverse plant collections. Admission is free, except at Foster Botanical Garden.
Only the highest standards of horticultural practice are pursued in maintaining the plant collections of the Honolulu Botanical Gardens. Together, these five gardens have the largest collection of tropical plants in the United States.
The Honolulu Botanical Gardens is dedicated to the conservation of flora from the topics and subtropics including our own native Hawaiian flora.
