Now that I look at the blooms on the LEFT, I'd say it might be a black eyed susan instead (Rudbeckia of some type). The picture is kind of blurry ....

It isn't feverfew. It's an Aster and will be hardy on Cape Cod. I'll leave it to the US experts to say which Aster. But we call them Michaelmas Daisies as a blanket term for the late summer flowering ones. This post was edited by florauk on Thu, Sep 26, 13 at 7:21

I thank everyone for the helpful input. It didn't occur to me to mention in my original post that two hail storms swept through in July and destroyed most everything (including 5,000 to 6,000 roofs [4 of ours] and countless cars [1 of ours] and windows [only 4 of ours - lucky!]). The daisies recovered enough to come back into bloom, but, yes, they and the rest of the yard aren't very pretty. Being in a shadier spot of the yard probably doesn't help either.

AAGGGHHHH! The more I look at them, the least certain I become. It could possibly be the Aglaia, or the Ice Star. I wish I had taken a picture of it! Are all daisy seeds the same? If so, I could look those up and see if I even got any of them or not. Thanks for all the help guys!!!
