I've been unsuccessful in identifying this tree. Hope you can help. This tree is in Bowling Green, KY , zone 6a/6b. Age unknown. I haven't seen another one in this area. Planted by previous owner, who said it was rare. This is my 1st post. I hope I have downsized my photos properly. April 20 - Tree bare, leaves beginning to form on terminal branches. May 5 - Leaves out. Some already 12". May 28(2008) - Tree in bloom. Single, white, upright. Center of faded blooms will continue to grow throughout the summer. Seed cones grow to about 3". Leaves measure 1-2ft by late summer.
