Whats it to ya?
pondboy, mapeles are native to ALL of the north american continent so more than likely the ones you are thinking of are native. With the very noteable exeptions of Norway and Amur maples, of course.
Aspens are a exelent tree. its unfortunate that trees from the rockies are dug up and sold to unsespecting byers in the east. The trees are not regionally adaped to the reagon. The same species does, however, more than likeyly grown grow in your area Lavenderdawn as aspens are found in a wide band across the whole North american continent
