I have four of these in my yard. I just moved in and can't figure out what they are. They seem to be some type of Magnolia tree. I am in IN zone 5b if that helps. The trees have blossoms, but I can't think of the last time I saw them. The leaves are fairly large and are almost fuzzy (not slick and glossy). Average height between the four is probably around 15 feet. Here are some pics. Thanks in advance! Jonathan
