Krohn Conservatory

Krohn Conservatory is a renowned public greenhouse located within Eden Park in Cincinnati, Ohio. Opened in 1933, it is operated by the Cincinnati Park Board and is celebrated for its extensive botanical collections and distinctive Art Deco architecture. The facility features numerous climate-controlled rooms and hosts popular seasonal floral shows that attract visitors from across the Midwestern United States.

History

The conservatory was constructed during the Great Depression with funding from the Works Progress Administration, a key New Deal agency. It was named in honor of Cincinnati City Council member Irwin M. Krohn, who advocated for its creation. The building officially opened to the public in the spring of 1933, becoming a centerpiece of the city's park system. Over the decades, it has undergone several renovations and expansions, including a major addition in the 1990s that added the iconic Pacific Island Waterfall exhibit. The conservatory has survived challenges such as the Ohio River flood of 1937 and continues to be a vital educational and cultural resource for the Cincinnati metropolitan area.

Architecture and design

Designed by architect H. H. Lindeman, the structure is a prime example of Art Deco architecture, characterized by its geometric forms and streamlined appearance. The exterior is notable for its use of Indiana limestone and large, curved glass panes that form the soaring greenhouse roofs. The interior layout is organized around a central Palm House under a 45-foot high dome, flanked by wings housing distinct climatic environments. Notable design elements include the original terrazzo floors, intricate wrought iron railings, and the modernist Pacific Island Waterfall, which was designed by the firm of John R. R. H. Associates.

Plant collections and exhibits

The conservatory houses over 3,500 plant species in five distinct climatic zones. The Palm House features towering specimens like the Canary Island date palm and a collection of cycads. The Tropical House replicates a rainforest environment with orchids, bromeliads, and ficus trees, while the Desert House showcases cacti and succulents from the Sonoran Desert and Madagascar. The Bonsai Collection includes miniature trees curated by the Cincinnati Bonsai Society, and the Butterfly Show during spring features live Lepidoptera from around the world. A dedicated Orchid Display highlights species from Costa Rica and Southeast Asia.

Seasonal shows and events

A major attraction is the annual rotation of themed floral shows, which begin with the Butterfly Show in April. The summer typically features the Summer Show with vibrant annuals, followed by the Chrysanthemum Show in autumn, a tradition since the 1930s. The winter season is marked by the popular Holiday Show, which includes model trains and thousands of poinsettias. The conservatory also hosts educational programs in partnership with the University of Cincinnati and special events like the Cincinnati Flower Show. These displays are designed by the horticulture staff of the Cincinnati Park Board.

In popular culture

The conservatory's striking appearance has made it a filming location for several productions, most notably scenes in the 1998 film The Rainmaker, directed by Francis Ford Coppola. It has been featured in episodes of the television series ''Supernatural'' and serves as a backdrop for local news segments by WCPO-TV. The venue is also a popular site for wedding photography and community events like the Cincinnati Music Festival, further cementing its iconic status within the cultural landscape of Southwestern Ohio.
