The nutrient-rich volcanic soil combined with a rainy environment provided the resourceful Hawaiians of the area the opportunity to create one of the most prosperous farming communities in all of Polynesia.
The area had complex fish ponds, domesticated animal pens, various large farming beds, and was famous for the cultivation of pink taro root stock, a coveted item to the Ali`i (the Hawaiian elite).
[1][2] Much of the garden floor was once cultivated for taro, sweet potato, and bananas, with new crops and orchards introduced by Europeans after their arrival.
Kupopolo Heiau, on the Haleiwa side of the valley's outer entrance, was likewise built under the guidance of the Kahuna Nui Kaopulupulu.
The Kahuna Nui were essential to Hawaiian society because they were the experts in various fields like farming, healing, spiritual guidance, fishing, and teaching both the Ali’i and the common people.
Hewahewa turned to Christianity, repudiated Hawaiian gods, and assisted in the destruction of all heiau and religious idols, along with Kamehameha II and Ka'ahumanu (his co-ruler).
The first Europeans to touch the island of O’ahu were the crews of the Resolution and the Discovery shortly after the death of Captain Cook in 1779.
It is located at 59-864 Kamehameha Highway, Haleiwa, Oahu, Hawaii and is open daily except for Christmas and New Year's Day; an admission fee is charged.
Other major collections include the hibiscus evolutionary garden, araceae, bauhinia, bromeliaceae, heliconia, liliaceae, as well as bamboo, begonia, ferns, tropical fruit, etc.
