Have you ever seen a Moon Tree?
The seeds of five different tree species — loblolly pine, sycamore, sweetgum, redwood, and Douglas fir — orbited Earth's natural satellite, but they did not land on it, which is a crying shame if you ask me.
Once the seeds returned to Earth, they were planted in various places around the world.
No noticeable differences have been detected between the Moon Trees and trees grown from seeds that have never left planet Earth, but I think the story behind them is awesome nonetheless.
I hope I get to meet a Moon Tree one day.
On Wikipedia, you can find a list of where the Moon Trees are planted.
