Eryngium prostratum!!

Nice work, Keith! This crazy little blue Q-tip of a plant is one of the wackiest things I've ever seen. I mean, it blows me away that this thing is related to big bad Rattlesnake Master (E. yuccifolium). I saw it ten years ago on the margin of a pond in southern Missouri and again last week on the edge of the Ozark escarpment near Poplar Bluff. It was growing in large mats with Diodia virginiana and Polypremum procumbens (a state listed species). If you really want to appreciate the genus Eryngium then Google Image "Eryngium leavenworthii" and brace yourself.
