Hi lamKriya,
This tree seems to be a keeper, but not magnolia and nothing I know as well.
The tree is healthy, yet the fruits are small for a magnolia .
So now, Lowes is selling at least 4 varieties .
If Lowes has higher demand on fig-trees ( or bad feedback ) , they may well have placed orders at new suppliers/nurseries, and you'll see them selling more strains - or at least more mislabeled trees :( .
Then, it is a matter of luck to buy a very interesting strain, even if mislabeled ... So going by the leave's shape if you want to choose new trees is recommended .
Here, out of the blue, a nursery placed an order to a nursery from southern France - the label was made by the "breeding" nursery and one could see the source of the tree.
