I recently purchased this Japanese Maple and was curious to get others opinion on it. The thing that attracted me to this tree first was the mature bark forming along the trunk and some of the branches. The worker assured me that it was not an arakawa but I have never sen bark like this form on a regular green maple. I want to increase the size of the tree so I am planning on repotting it into a grow box next Spring. Any advice and suggestions welcome!!!!
