That tree is like me, mid-thirties and locally grown. Its Acer palmatum 'Shishigashira'. It gets all day sun and does not seem to mind the mid-summer heat. I have become good friends with the guy who originally grafted it and grew it up to the point that I bought it, so its a very special tree to me. In the first picture of #39 its little brother Ojishi is in the ground in front of it.
