I saw this at the ANMed Lake in Anderson, SC. It looks like a Yellowspine Thistle but I didn’t think they were in SC. What do you think?
this is sometimes called yellow thistle, but not when it has reddish flowers. It can have either. It is Cirsium horridulum, a rather common thistle in open sunny areas, especially roadsides, and it is native.
I apologize for the delay in my reply. I had software issues that only now have been fixed. Thank you for your patience.
