Definitely a Strawflower!

Luckily there has not been a killing frost since I took the picture of my mystery flower.  It has opened enough that I can see that it is a strawflower (Helichrysum).  What I didn't know is that strawflowers are in the sunflower family--but if you look at it you can see the similarities.  If you click on the image you can see all the ants happily playing around the stem.
