Let my backyard go to clover and I've never been happier

43. Yep, very good

There most definitely are native clovers in the Piedmont region. We have a member of our organization doing a restoration near Raleigh. Lots of species we don't see here.

From the North Carolina extension service:

Trifolium carolinianum, or Carolina Clover is a native wildflower that is typically found growing in lawns, along roadsides, in cemeteries and in thin, sandy pine or scrub oak woods. It is often confused with White Clover. Although a native of coastal North Carolina, it has not been spotted for an extended period of time. The closest location where it can be seen growing is in South Carolina, near the North Carolina border.

Trifolium reflexum or Buffalo Clover is a North Carolina native perennial in the bean family. A rare plant that was once abundant, it has seen a strong decline in the past few decades. In North Carolina, it has been given a State Threatened status. On the rare occasions that it is located, it is seldom in large stands. It tends to become shaded out by taller species as well as declining for no apparent reason.

It would be pretty interesting if you have one of the rare native clovers there.

Common Chickweed and Purple dead nettle would be no surprise, they are in every lawn in the country I think. You may well have Common blue violet in your lawn.
