The search is on for the perfect Christmas tree.  Chal Landgren, at Oregon State University, says they think they found it in Turkey. It's called a Trojan Fir. It's a tree with several benefits. “That means they use fewer pesticides; they also aren't prone to root rot like the Nobel Fir.”  They'll plant these new trees and watch their growth over several years to see whether they'd make a good replacement for the Noble Fir.
