Can you identify this tall weed?

Asked August 23, 2018, 8:00 PM EDT

My father and I are having difficulty identifying this tall weed. Dad lives in western Massachusetts (Amherst) and they have had so much rain he said this new weed is taking over his garden and growing fast. Can you help identify it??

Hi. Has this weed flowered yet? I am thinking it mostly resembles a thistle. What have you ruled out? It will make the ID process easier if you could send a photo when it blooms. Thank you.

Hi again. Try googling Erechtites hieracifolia. Most info says the flowers are what will ID positively.
