Missouri Botanical Garden

Founded in 1859, the Missouri Botanical Garden is one of the oldest botanical institutions in the country and a National Historic Landmark. The Garden is a center for botanical research and science education, as well as an oasis in the city of St. Louis - 79 acres of beautiful horticultural display, including a 14-acre Japanese strolling garden, Henry Shaw's original 1850 estate home, and one of the world's largest collections of rare and endangered orchids. The Missouri Botanical Garden works to discover and share knowledge about plants and their environment in order to preserve and enrich life.
