The Garden began in 1899 when paleontologist Othniel Marsh (Yale B.A. 1860) bequeathed his home, grounds, greenhouses and plant collections to the University. The botanical garden was designed by landscape architect Beatrix Farrand during the 1920s and 1930s as part of her design for the Yale campus. Today the Garden supports research and instruction, and is a public greenspace. Only remnants of Farrand's design remain, although restoration work has begun. The greenhouses contain 2,000 orchids, an extensive collection of plants from tropical regions and arid climates, and an insectivorous collection.
