Keʻanae Arboretum is an arboretum and botanical garden located on the Hana Highway about 1-mile west of Keʻanae, Maui, Hawaiʻi, United States.
Before the 1940's the land the Arboretum sits on was used to farm food, medicine and fiber-producing plants. From 1946 until the mid 1950's, it became an agricultural work site for prisoners at Ke'anae Prison Camp. It was established as an arboretum in 1971.The arboretum lies alongside the Piinaau Stream on taro cultivation terraces and within a rainforest, and contains two short walking trails. It contains about 150 varieties of native and introduced tropical plants, including gingers, hibiscus, papaya, and various types of taro. Trees are labeled with common name, scientific name, and origin.
