In spring and summer my Japanese maple is the same green all around. But when Fall comes the tree looks like 2 trees in one. One side always gets yellows and oranges, while the other side gets deep purple, almost black, and reds.

Every year the colors are the same and the tree looks split in Fall.

Is it possible my tree is 2 trees grafted into one? But why in summer do leaves all look the same?

Whatever the case we get great comments yearly by people if how awesome the tree looks each fall.
