The Conservatories at Brookside Gardens consist of two glass buildings joined by a short hallway. The Conservatories house a large collection of tropical plants including banana, giant bird of paradise, and Calliandra (Powderpuff tree) as well as seasonal displays in the spring, summer, and autumn and a terrific holiday show. The Conservatories are also used for special programs, such as the winter Garden Railway display and the summer live Butterfly Exhibit.
The Conservatories at Brookside Gardens host four changing shows each year:
- Spring Display: January through April
- Summer Display & Wings of Fancy Live Butterfly Exhibit: May through mid-September
- Fall Chrysanthemum Display: October through mid-November
- Winter: December
