When we move to our present location, I planted 2 Sun Valley Maples out front. Thought they were identical,but when they turn color in the fall.one is a darker red and the other has more orange. Is this common with these that the colors vary? I know it is in some others. Didn't know if I ended up with 2 different types,although the leaves appear to be the same size. Not that I'm planning on changing anything,but just curious.
