Although this 14-acre site has been used since 1979, the modern version of the Greater Des Moines Botanical Garden opened in 2013. The area is divided into a series of outdoor gardens, a geodesic dome conservatory, and several indoor gardens.

Containing more than 1,000 taxonomic groups of tropical and arid plants, the conservatory also displays the first corpse flower to bloom in Iowa. The Gardeners Show House contains seasonal exhibits.
