Acer palmatum 'Dissectum' This is the largest dissectum I know of in our area. The picture does not give a good impression of size. As a reference to size, the stone directly to the right of the tree is over 6' tall. I am 6'6" and can stand under the lowest branch that stems off the center and goes horizontal off to the right side. In the 2nd photo you can see someone standing along the right back corner of the tree. This tree has an amazing and majestic presence in person that is very difficult to capture in a photo. I estimate the tree to be 20' tall and 28' wide.
