1. Moon Sycamore Marker
Inscription.
This American sycamore is grown from one of the small number of seeds carried to the moon and back by Astronaut Stuart Roosa on the February 1971 Apollo 14 flight.

The seeds were germinated by a US Forest Service scientist at NASA's manned space center at Houston, Texas. The project is intended to focus attention on the past and future importance of trees and forest resources.

Regarding Moon Sycamore. The scientific name for the American Sycamore tree is actually Platanus occidentalis. There appears to be an extraneous "n" in the marker inscription.
 
Also see . . .  The "Moon Trees".
Apollo 14 launched in the late afternoon of January 31, 1971 on what was to be our third trip to the lunar surface. Five days later Alan Shepard and Edgar Mitchell walked on the Moon while Stuart Roosa, a former U.S. Forest Service smoke jumper, orbited above in the command module. Packed in small containers in Roosa's personal kit were hundreds of tree seeds, part of a joint NASA/USFS project. Upon return to Earth, the seeds were germinated by the Forest Service. Known as the "Moon Trees", the resulting seedlings were planted throughout the United States (often as part of the nation's bicentennial in 1976) and the world. They stand as a tribute to astronaut Roosa and the Apollo program.
