In my back yard there is this great little magnolia tree. From the first picture you can see that it is fairly upright growing. Currently it is about 10 wide by 16' high. The house is 50 years old so it isn't any older than that. The buds are a pale pink and open into a white flowers flushed with pink along the middle, having approximately 20 tepals. At first I thought it was a star magnolia, but it seems too upright for it to be that. A Kobus hybrid, Jane Platt, Leonard Messel... none of these seem to match. If helpful I can post some pictures of it leafed out. Any ideas? Thanks.
