A part of Bishop Museum, the Amy Greenwell Ethnobotanical Garden focuses on the traditional Native Hawaiian uses of plants and land, and on the conservation of that plant material. This 12 acre garden includes a 5 acre remnant of the prehistoric agricultural Kona field system of the ahupua'a of Kealakekua. The garden layout illustrates the four vegetation zones utilized by Hawaiians in the Kona region: coastal, lowland dry forest, food and fiber crops, and upland forest. Feature collections include banana, Hawaiian economic plants, native Hawaiian plants, sugarcane, and taro.
