This is growing equally tall (4-5 feet) in stoney clay and in old terraced garden soil...the areas are open but with trees all around the edges.... really nothing else is growing with it except an occasional sweet gum sprout and a bit of poison ivy around the edges.
EDIT...we think the odd numbers of petals varying from flower to flower is a clue...they seem to grow that way and it is not from loosing petals.

Well, it is clearly in the daisy family. You can tell because, if you look really closely, the centers are made up of tiny, separate flowers. Unfortunately, I haven't access to a wildflower guide for your region. Can you get one through your library system?
