SAH I've heard that Magnolia is growing very, very slowly, so I think that it was of such size as in the photo to 100 years.
Seriy What about tree piona it in the first year I pribolel, the second seems to be moved away and now for all 4 years has grown very little (see tree peonies at the Odessa Botanical Gardens, I think they're too 100letnie apparently they grow too slowly).
Seriy is my friend peony flowered after 8 years after planting and do not look too large, so wait for every year
SAH saw magnolia blossoms are bigger in America (grown right next to the house), the beauty simply mad, stood and watched a few minutes, nemogla come off, sorry no photos.
