Official State Tree of Utah
Utah designated quaking aspen as the official state tree in 2014, replacing the original state tree; blue spruce, adopted in 1933. All State Trees
This change began with fourth-grade students at Monroe Elementary in Sevier County. The students felt that the blue spruce did not represent Utah as a whole. They championed the remarkable and unique aspen as the tree symbol of Utah. A stand of aspen trees is really one huge organism that grows from a single root system. Quaking aspen (Populus tremuloides), also called trembling aspen, is found in all 29 Utah counties.
