What was once the grounds and the tree nursery of the historic State Penitentiary in Boise's Old Penitentiary Historic District, is today a living museum that holds a diverse botanical collection, educational programs, high quality entertainment and numerous cultural and community events. This lush 15-acre mosaic of pleasant shade and splashes of color contains domestic and Idaho native plants that are well adapted to the local conditions.

There are more than 800 species from 42 families, planted in 14 distinct specialty gardens at the Idaho Botanical Garden. Some of the specialty gardens are: The Water Conservation Landscape, which focuses on plants that require very little water; The Meditation Garden; and the Lewis & Clark Native Plant Garden, which contains 145 plant species that the two explorers collected between Great Falls in Montana and The Dalles in Oregon.
