Weed or Flower
I couldn't ID this myself, so I sent a request to the FABULOUS Plant Identification page on Facebook. Professional plant people usually help really quickly; they responded that this is trifolium arvense. Here's a link to info about this plant. Since it grows wild, I guess you could consider it a weed; I prefer to think of it as a wildflower!
https://www.illinoiswildflowers.info/weeds/plants/rf_clover.html gives good info about this plant, although it only talks about it in Illinois.
