Description

Am always unsure about ID of those thistles, probably because there are several quite similar but distinct species, and i did not care enough about knowing different characters of.

Description from Wikipedia

Cirsium is a genus of perennial and biennial flowering plants in the Asteraceae, one of several genera known commonly as thistles. They are more accurately known as Plume thistles. These differ from other thistle genera (Carduus, Silybum and Onopordum) in having feathered hairs to their achenes. The other genera have a pappus of simple unbranched hair.
