Bolz Conservatory can be enjoyed year-round

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.
