"The beautiful Missouri Botanical Garden is also known as the Shaw Garden, after the businessman and botanist Henry Shaw (1800-89) who laid it out in 1859. In the southeast part of the gardens are the richly appointed Tower Grove House, Henry Shaw's "garden house". The gardens themselves comprise a lovely rose garden, the rather unusual Climatron, built in 1960 for tropical plants, a Japanese Garden, an "aqua-tunnel" under a water-lily pool, and a herbarium."
