Here is an Amur maple that I dug yesterday. I planted this tree 4 years ago after pulling out of a pile of dead trees at the local nursery. Two years later I trunk chopped it and left it in the ground to heal. Two years after that the major wounds are healing, the top 6 inches is dead but there are strong branches all around the tree so I am not worried about dieback. Two more years in the training pot and then it may start to look nice. The base is about 8-10 inches wide, the variety is "Flame".
