Missouri Botanical Garden: A Legacy of Botanical Research and Horticulture
Located at 4344 Shaw Boulevard in St. Louis, Missouri, the Missouri Botanical Garden stands as a premier center for plant research, conservation, and public education. Often referred to as Shaw's Garden after its founder, the institution blends Late Victorian architectural charm with cutting-edge scientific facilities, making it a cornerstone of botanical study in North America.
Beyond its aesthetic beauty, the garden is a powerhouse of scientific data. Its herbarium—a collection of preserved plant specimens—is the second largest in North America, housing over 7.5 million specimens. This collection is identified by the Index Herbariorum code MO, a standard used globally when citing these specific specimens in scientific literature.
Key Facts
- Founded: Opened in 1859 by philanthropist Henry Shaw.
- Scientific Standing: Home to the second largest herbarium in North America.
- Historic Status: Listed on the National Register of Historic Places (1971) and designated a National Historic Landmark (1976).
- Major Attractions: The Climatron geodesic dome and the Seiwa-en Japanese Garden.
- Global Impact: Co-creator of The Plant List, a comprehensive internet encyclopedia of botanical nomenclature.
History and Heritage
The garden's development began around 1850 under the vision of Henry Shaw, a British immigrant who arrived in St. Louis in 1819. Construction officially commenced in 1855, and the gates opened to the public in 1859. Upon his death in 1889, Shaw donated the conservatory to the city.
The site also holds significant historical weight regarding the Underground Railroad. In 2024, the Tower Grove House was added to the Network to Freedom. Records indicate that in 1855, four individuals enslaved by Shaw escaped from the house with the assistance of Mary Meachum, though some were captured shortly after crossing the Mississippi River.

Architectural Evolution: The Climatron
In 1959, the garden transitioned into the modern era with the construction of the Climatron. This geodesic greenhouse, which opened in 1960, was one of the first of its kind. Designed by architect and engineer Thomas C. Howard, it replaced the former Palm House to simulate a lowland rainforest environment for approximately 1,500 plants.

World-Class Research and Libraries
The garden is not merely a public park but a critical hub for systematic botany (the study of plant diversification) and plant taxonomy (the science of naming and classifying plants). The Peter H. Raven Library supports this mission, providing 85% coverage of all literature ever published in these fields.
