Second opinion on this plant/weed?
I hope it's permissible to cross post from what I posted in the "weeds" forum a little while ago. I wondered if I could get a second opinion and possibly a specific species of the plant I've picture below. I have googled a lot to find a match for the suggestion that this is a thistle (it probably is but what kind)?
Thanks in advance and if I cannot cross post I will delete this entry.
Here is a link that might be useful: What is this plant/weed?
