Probably  Onopordum spp.,

but should not be present in sweden

it would be necessary to have a sample of the dried flower

or enlarged photos of the flower

for classification

Dear Salvatore,

Thank you for your information. I checked the references and found it similar.  In fact,it is a native to Europe and invasive species to North America, South America, and Australia. 

Centaura - thistle looks like Cardus nutans or C.acanthoides.

Onopordum acanthium ... does occur in Sweden!

Thank you Ray and Theodor for your responses. Best regards, Hari

I agree with the identification Onopordum acanthium L.

It seems Onopordon acanthium, pollen grains can help you to identify this species, is different from Carduus and Cirsium

Dear Magdelena Stoyanova,
