December of 2008. She had no place to transplant it after the holidays, and, rather than discard it, she gave it to me to plant in my back yard. Much to my surprise the new growth was not spruce, but pbvious pine needles. There is no evidence of any grafting. The original lower portion of the tree remains healthy spruce, but all new growth is pine, including sme pine needles growing on the orinal spruce branches, as seen the the photographs. No one to whom I have shown the tree has rational any explanation for this phenomenon, and I am curious to learn what the explanation might be for such a transition. Is this (1) unusual, (2) reasonably common, or (3) totally bizarre? Here are the photos: http://www.flickr.com/photos/10531633@N00/ Thanks, TMS Other posts:
