Your plant has a number of similarities with Melancholy Thistle (Cirsium heterophyllum) in terms of flower shape and form and the hair like prickles on the leaves. I don't know if that species extends to Romania.
Thanks for taking a look. That species was what first came to mind to me but this one didn't have the cottony underside to the leaves which probably, but perhaps not certainly, rules out Melancholy Thistle. They have a whole raft of amazing things out there much of which is unknown to me.
