Cirsium horridulum from Dixie South Carolina

Can you tell me the name of this wild flower?

Hi Dixie,

your wildflower is a thistle, most likely the bristly thistle or bull thistle, Cirsium horridulum. I didn’t see the whole plant, so I cannot be 100 % certain. Cirsium horridulum has a rosette of very prickly leaves on the ground in a circle at the base of the stem. It is quite common in pastures and roadsides. Yours is past flower with the hairs on the seeds showing.
