Missouri Botanical Garden

Founded in 1859, Missouri Botanical Garden is the oldest continuously operated botanical garden in the U.S. "We're widely considered one of the top three botanical gardens in the world, noted for our expansive science and conservation efforts around the globe and for our stunning horticultural displays," says Karen Hagenow, the garden's public information officer. Don't miss the Climatron conservatory, a 50-year-old geodesic dome that houses a tropical rainforest.
