This is a Jpanese maple, Acer palmatum 'Kiohime'. It is styled very much like an old broadleaved tree and not like a typical bonsai. As so often it looks better without foliage. This great tree miraculously found it's way into my garden recently. The first images are from February 2009 when it was still in Italy. When I got it and it was just a green ball and the pot was way too small for my taste. I put it into a larger pot (Petra Tomlinson) which is better suited, I think. Actually I just placed the intact rootball into the larger pot and surrounded it with substrate. I do not want to repot such tree in fall. April would be a much better time. Then I cut out a few holes into the crown to give it some structure. The real styling will happen in winter after the foliage fell off. I think this will become a very important piece of my collection.
