Ray Drive, Des Moines, Iowa, United States, on the east bank of the Des Moines River. Interest in a Des Moines botanical center began in 1929. A city greenhouse was acquired on the west side of the river in 1939, which served the city as a production and display greenhouse until the Botanical Center was completed in 1979.
