The Iowa Arboretum & Gardens was established in 1968, born from a resolution passed by the Iowa State Horticultural Society in 1966 to create an arboretum to serve the entire state. The Horticultural Society, celebrating its 100th anniversary at the time, purchased a 40-acre parcel of land to begin this ambitious project. The deed for the land was paid off by 1972, solidifying the arboretum's foundation as a 501(c)(3) non-profit organization dedicated to horticulture and natural appreciation.
