The Friends of Lyon Arboretum is a non-profit membership organization working to provide funding and support to the Harold L. Lyon Arboretum.

Since its founding in 1975 Friends of Lyon Arboretum (“FLA”) has been managed by a volunteer Board of Directors whose mission is to raise funds in support of programs at Lyon Arboretum and to promote community awareness of the only easily accessible tropical rain forest on the island of O‘ahu.

Located on 194 acres in upper Mānoa Valley, the Harold L. Lyon Arboretum is a biological field research facility and maintains an extensive, managed collection of native and non-native plants including palms and exotic tropical plant materials in a botanical garden setting. The gardens are open to the public six days a week.
