Episode 86: The History and Aroma of Christmas Trees

 

It’s not really Christmas without a Christmas tree. Casey gives a very brief history of Christmas trees and introduces us to the tree that was selected in 2019 for the Idaho State Capitol Building. The tree is a Colorado blue spruce (Picea pungens), which historically has had many other uses apart from being used as a Christmas tree.
