Q- How many panes of glass does the Conservatory have?
A- Volunteer Park Conservatory has 3,426 panes of glass. They were originally held in place by a swamp cyprus wood support structure. These supports were replaced in the 1950s, then again in the 1980s, before being replaced by long lasting aluminum in a restoration phases which started in 1993. The final phase of the Conservatory restoration was completed in 2014.
Q- What is the oldest part of the building?
A– The lunette or peacock window over the main entry is the only original wood and glass piece remaining from 1912 after two renovations. It was restored in 2000.
Q– What is the oldest plant in the Conservatory?
A– The oldest plants on display now are probably the Sago Palm (Cycas revoluta) and the Jade Tree (Crassula argentea). Both are over 100 years old.
Q– Why are the windows white washed in the summer?
A– A chalky paint sprayed on the glass in early summer to protect the plants from excessive sun and heat. In the fall the white wash is removed when days become shorter and darker.
Q– How do you control the temperature and humidity?

The overhead and under-bench vents are also computer controlled to regulate temperature and humidity. There is a sensing device in each house.
