The Greater Des Moines Botanical Garden, an indoor conservatory of over 15,000 exotic plants, is one of the largest collections of tropical, subtropical, and desert-growing plants in the Midwest. The Center blooms with thousands of flowers year-round. Nearby are the Robert D. Ray Asian Gardens and Pavilion, named in honor of the former governor whose influence helped relocate thousands of Vietnamese refugees to Iowa homes in the 1970s and 1980s. Developed by the city's Asian community, the Gardens include a three-story Chinese pavilion, bonsai landscaping, and granite sculptures to highlight the importance of diversity and recognize Asian American contributions in Iowa.
