Every year from April to June I believe there is an exhibit. It changes rooms occasionally. However, it is most often in the local room that has citrus trees and local type flowers such as phlox and marigolds. Krohn has many different types of special exhibits that can be found on their calendar online for more information.
This occurs during spring time. Check out holiday displays this Christmas
