Hi John,
I really appreciate your input. The 'colony' of about 15-20 feet in diameter was very attractive in fall color, so I couldn't resist stopping for a closer look. The tallest (I guess) was at most 7-8 feet.This area is in a fairly dense wooded location next to a narrow country road. If given a chance I'll collect a branch and see if I can get a close up of the buds as you suggest. I've even thought about adopting a small shoot for my own landscape, but I'm not willing to dig without permission.
I remember your posts from years back at the old DG site. And I am glad to see you over here at ATP as will many others!
