“And both that morning equally lay
In leaves no step had trodden black.
Oh, I kept the first for another day!
Yet knowing how way leads on to way
I doubted if I should ever come back.”
“Moon Trees” were grown from seeds taken to the moon in early 1971. After orbiting the earth with the Apollo 14 mission, these tree seeds returned to earth and were germinated by the Forest Service. After being planted with their earth-bound counterparts, these seedlings showed no discernible difference after twenty years of growth.
