Pink Family (Caryophyllaceae) - This plant is definitely a member of the "pinks" family, but I'm not certain whether it is "Sweet-william Catchfly" (apparently there are several plants that go by that name) or "Bouncing Bet" (Saponaria officinallis). I was unable to identify it more exactly with the fields guides, and I recieved conflicting feedback, so I'm going with the non-specific classification... Blooms in the summer. (Photographed in WI)
