I'm positive this was not saffron thistle, the leaves were quite different, not as stiff as saffron thistle and differently shaped.
I think this is actually a Centaurea calcitrapa.

Might be actually, not too familiar with that species though

Yeah, that'd be right, it is a plant that I was unaware of until recently. I collected it on the coast at broulee island.
