These leaves look more like Onopordum to me than Carduus

In this small area, there were 3 types of Thistles (Onopordum acanthium, Cirsium vulgare and Carduus nutans). We removed the parent plants but found some thistle rosettes which we didn't take them out yet as we wanted to know species. We will monitor them to see them grow a little more so that we can be sure about the species.
