So many people have claimed that a 35 ft tall Japanese Maple is the largest JM that you'll ever see. The first two maples are 35 ft tall. The red is from my yard. The green one we spotted locally on the side of the street. The last photo is a picture of a 45-50 ft Japanese maple that I spotted at a customer's house. From the description of its size, I thought for sure that it was going to end up being a silver-leaf maple or a sugar maple, or that it's size had been overestimated. This wasn't the case. It is clearly Acer palmatum. My brother is in the photo with arm up at the base of the tree. This reach is an 8 ft 3inch reach. You can see that this maple is gigantic. Has anyone spotted a Japanese maple larger than the tree in the picture on the far right? All these trees are located in Western North Carolina.
