This is a blue Araucaria cunninghamii I grafted a couple of years ago. The blue 'form' (var. glauca) is found in certain areas of Australia (Magnetic Island) and also in PNG. The source of the scion was a seedling blue variant in a batch of green ones a friend raised. The graft is now growing happily in my garden and came through last winter (which was rough due to the wildly fluctuating temps) with minimal damage. From April 20, 2010
I also have a graft of a blue A. heterophylla I will post. It is a plagiotropic one, so it will just be a groundcover.
