Bells?

I was doing reflection shots today while cooking on the grill when I noticed these tiny, tiny white flowers in an old flower garden. I should have shot them in other modes, but the meat was starting to smoke. These flowers are maybe 4mm wide, not sure what they are called.

I tried to get some shots facing up (viewfinder in ground) but none were clear enough.

freehand, super macro
