Circium perhaps Circium vulgare.

A thistle for sure but with those spiny stems and small flowers it doesn't look much like any of the Cirsiums around here in the NE. How about Carduus acanthoides, spiny plumeless thistle?

Lots of different Cirsium: https://en.wikipedia.org/wiki/Cirsium

That's for sure. Thinking more about this one, I would go along with Cirsium vulgare. But the Carduus is worth considering.

It looks more like Carduus crispus to me. The Cirsium vulgare I find here usually has smaller heads, in relationship to the receptacle, and the stems don't have as many lateral divisions.

So it's a thistle either way... Very beautiful plant, and like I said it was covered with bumblebees.

was hoping to grow some at home but it seems they are alien weeds. Thanks for the ID though!!
