The conservatory was originally built in 1929 by the Park District of Oak Park using a kit design from the Lord & Burnham company.
The structure features a unique 'monitor' roof style common in early 20th-century horticultural buildings.
The collection includes rare specimens such as the corpse flower (Amorphophallus titanum), which blooms only periodically.
The site acts as an 'Urban Oasis,' providing a protected climate-controlled environment for species that cannot survive Illinois winters.
The Desert Room is specifically designed with a gravel base to simulate arid environments for succulent growth.
The conservatory operates an active community program for seedling distribution and urban gardening education.
The Oak Park Conservatory is a historic glass-enclosed botanical garden housing a collection of over 3,000 exotic plants. It features three primary showroom areas: the Mediterranean Room, the Tropical Room, and the Desert Room. The facility originated in 1929 and is listed on the National Register of Historic Places. Visitors can observe diverse botanical specimens, including ferns, cacti, and flowering shrubs, alongside seasonal floral displays. Educational programs and plant sales are hosted throughout the year for the local community. The conservatory operates under the management of the Park District of Oak Park. The structure underwent significant renovations in the 1980s to preserve its glass architecture. It serves as a biological research and conservation site within the Chicago metropolitan area. The gardens include outdoor components surrounding the main conservatory building.
