The Bolz Conservatory will soon undergo its first major closure for maintenance since it opened in November 1991. The indoor tropical garden is scheduled to close from March 11 - June 14, 2024 for assessments and potential repairs of structural components like glass panels, metal framing, and the foundation. In particular, seals on panels will be checked for leaks, and framing will be inspected for water damage and rust. The assessment results will inform the planning, scale, and order of priority of any needed repairs.
While we’ll miss welcoming guests into the conservatory this spring, the closure will serve as an investment in the structure’s future, helping to prepare it for its next decades of serving the community as well as visitors from throughout the US and beyond.
The Bolz Conservatory will be open January 27 – March 3 for this year’s Orchid Escape exhibit, offering the perfect opportunity to enjoy the sights, sounds, and smells of the tropics prior to the closure. Our 16-acre outdoor gardens will remain open during the conservatory closure, and our Spring Flower Show will run March 2 - 24 to offer guests a first glimpse of spring color.
As we approach March, we’ll share more information on specific dates of the closure, and a City of Madison Engineering project page will be coming soon as a way to stay up-to-date on project details and milestones.
Enjoy a tropical paradise year-round in Olbrich's Bolz Conservatory, a glass pyramid filled with exotic plants, bright flowers, a rushing waterfall, fragrant orchids and free-flying birds.
The tropical Bolz Conservatory houses more than 650 plants representing more than 80 families and more than 475 different species and cultivars. These plants are native to tropical and sub-tropical regions throughout the world.
The glass pyramid measures 100 feet by 100 feet, rising to 50 feet tall in the center. The temperature in the Conservatory is maintained between 65 and 80 degrees Fahrenheit (between 18 and 26 degrees Celsius), and may warm to 95 degrees Fahrenheit on hot summer days. The relative humidity is kept above 60-percent year-round.
