Leaves look like what I bought as a BT too. Leaves and fruit sure look like Brunswick/Magnolia according to those who saw the pictures I posted.  They are just starting to swell now so it won't be too long provided the deer don't get them before I do. Dug out an old blueberry net and am hoping that will do the trick. Will post pictures when fully ripe.  Right now they look like run of the mill polka dotted fruits with a red eye. In past years, they have been quite tasty and so far all the heavy rains do not seem to have damaged them.
