Is this a form of primrose, grown in very dry, sunny, SC sandy soil?
Hi Mary,
this is Aureolaria pectinata, the combleaf yellow false foxglove. A very nice wildflower, for sure. Actually it is related to snapdragons. You can find out more about it here: http://uswildflowers.com/detail.php?SName=Aureolaria%20pectinata
