Story of the Tree
While the Douglas fir is one of the most common evergreens in Washington, this particular tree has a unique history.
During the 1971 Apollo 14 moon mission, astronaut Stuart Roosa brought hundreds of tree seeds with him into lunar orbit, including Douglas fir seeds that the U.S. Forest Service sprouted. The resulting seedlings were planted throughout the United States.
The first Washington state ‘moon tree’ was planted as a seedling on the Capitol Campus at its location on Capitol Way, near Tivoli fountain. It’s a very full and beautifully formed tree that has a place of honor on the campus, reminding visitors of the Apollo missions to the moon. The tree is marked by a bronze plaque that describes its significance.
In 2020, three more moon trees were planted using cuttings from the original campus moon tree.
