Below is a picture of a tree leaf and I'm hoping someone can identy the tree. The leaf measures 10 inches wide and 7 inches long. Whatever it is, it is a very fast growing. I found it growing in my back yard this past spring when it was approx. 5 inches. It is now aprox. 8 feet tall. Regina
Very likely Acer saccharinum. This crosses with A. rubrum to produced intermediate trees where both species are near one another, however the largeness of the leaves you have reported would just about have to make it silver maple. Giant wide-spreading brittle tree unsuitable for ordinary situations where it would be out-of-scale and might drop branches on structures, vehicles or people after it matures and starts to deteriorate.
Fortunately it is in a pot at the present time. I'm wondering if it is possible to stunt it's growth by keeping it in a pot. Any thoughts on this? Thanks for responding.
Runs counter to the inherent character of the tree. A naturally small dense tree would be a much better choice.
