Found on the roadside in partial shade and somewhat moist in the spring in Clarendon County
Hi Anne,
this is Salvia lyrata, the lyre-leaved sage, a rather common native plant, especially common along roadsides. It is in the mint family.
By the way, I seem to be unable to change the orientation of images. Sorry about that!
Sincerely,
Steve Hill, Botanist, SCNPS
