Venus' Looking Glass (Triodanis perfoliata)
The flowers on the lower half of the stem never open but are self-pollinating. The tiny seeds are wind-dispersed and the plant can become weedy or invasive in some locales. The main bloom period is spring to early summer. Venus' Looking Glass grows in full sun, and poor soil that is well-drained. They do best in areas with sparse or low vegetation. They are native to most of North America.
This is the first year I've seen them on my property but there must have been at least one plant last year because this year I've got about a dozen. By next year I'll know if it's going to become weedy. I'm guessing it won't because I haven't seen large patches of this anywhere around here.
