The Moon Tree can be found next to the Dunn Formal Rose Garden. It is actually an American sycamore that was grown from a seed that orbited the Moon with Stuart Roosa in Apollo 14's command module while Alan Shepard and Edgar Mitchell walked on the lunar surface.  Stuart Roosa, a former smoke jumper with the United States Forest Service, was approached about bringing the seeds into space and resulted as a joint NASA/USFS project to study the effects of weightlessness on seed germination and seedling growth. Other trees were planted in Brazil, Switzerland, at the White House and presented to such notables as the Emperor of Japan.

President Gerald Ford, in a bicentennial Moon Tree ceremony, called the trees living symbols of "our spectacular human and scientific achievements."
