This is the photo that christened "Jonathan's Christmas Tree." They were just exactly the same height for one summer. Then, the tree outpaced him, though he did pretty well for homo sapiens... 

About five years ago, Jonathan's Christmas Tree had gotten too big for its placement by the driveway, and it got cut down.  But Dad tells me that it planted one of its seeds first.  Jonathan's New Christmas Tree is about three and a half feet tall now, perhaps just about the height of the one in this photo.
