Can you help me identify this thistle. The photos were taken in August in LeFurge Woods Nature Preserve in southeastern Michigan.
Thank you. I was hoping it was not the invasive weed, but I guess it is. It is a lovely thistle though even if it IS a pest weed.

Jacobson is wrong, and can't be considered a reliable authority on the English names of European plants. http://wbd.etibioinformatics.nl/bis/flora.php?selected=beschrijving&menuentry=soorten&id=3834
