Larimer County, Colorado, US
On Dogs in Space, 150 to 200 meters S. of Crazy Horse. ~ 100+ ft. before dip on the way to picnic table.
Appropriately named since I barreled through snow to get out of here last year...
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.
