Yeah, those are just daisies. Gorgeous, nonetheless, but definitely not prickly poppies. Could this please be corrected, VicAd? And, yes, I will also go to the link to "report error".
Those are NOT Texas Prickly Poppy, the smaller picture is. Perhaps the president of the DeWitt Wildflower Association mentioned in the article should have been asked to identify the wildflowers pictured.
