Hmmm.. I can see now that it is not Antennaria. Mine in zone 4b have already produced seed. Blooms should never hang down, and the rear "scales" (the involucre - the red part if you had a red pussytoes) of the composite flower should number at least 20 if not 40-50. Your plant has zero. Like this:
Antennaria is a composite flower with many many individual flowers inside each pussytoe. I would lean towar Silene, but silenes have opposite foliage. Not sure what it is.
Time will tell....
