Spruce to Pine Puzzlement
This tree was bought as a 12" "living Christmas tree" by my daughter in
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 |

Juvenile foliage is different. For example here in France we have Stone pine (Pinus pinea) that typically grows that way : from seedling to 2 or 3 years old the young plant looks like the one shown on your pictures, with blueish foliage. Needles are not arranged by pairs or not grouped by 3 or 5 as they are normally for pines but disposed all around the shoot. After a while, about 3 years or so, juvenile foliage is not produced anymore and the pine finally starts looking like a pine ! Olivier -- http://nothofagus.free.fr http://florenligne.free.fr |

Thanks very much for your reply. It clarified the question completely for
me. I was not aware that juvenile foliage might be quite different from the adult type. TMS "TMS" wrote in message ...

This is quite common. It has something to do with adapting to
the environment that the plant is exposed to at different stages of growth. "TMS" wrote in message ... Thanks very much for your reply. It clarified the question completely for me.
