Apollo 14 astronaut Stuart Roosa carried hundreds of tree seeds around the Moon, and their descendants still grow on Earth

The "Moon Trees"

During Apollo 14, command module pilot Stuart Roosa, a former U.S. Forest Service smoke jumper, orbited the Moon with hundreds of seeds from loblolly pine, sycamore, sweetgum, redwood, and Douglas fir packed in his personal kit. The bags burst during post-flight decontamination, but the seeds still germinated. Most seedlings were given away for the 1976 bicentennial and planted across the U.S. and abroad, including at the White House and in Brazil and Japan. No complete record was ever kept.
