Could the image attached be a wild parsnip weed which just took over my pachysandra patch? Would appreciate a confirmation or correction of this new little monster in my yard. Thank you.

Its not wild parsnip. Maybe if you could add some more photos of the plant, we could Identify what it is. Also, please update your information so we know where you live. Not all 'weeds' occur in all places.

Thank you for the quick reply. I am in zone 5 (suburb of Chicago IL). Below are all the photos I had taken of the plant. I only came to the conclusion on my own after searching out leaf similarities from the internet. Appreciate your help. Thank you.

I agree that it's definitely not wild parsnip -- do the leaves have any particular odor?

Re: Odor, I didn't get close enough to sense any odor.

Reminds me of Osmorhiza, although I can't see enough detail in the pictures to be certain of that.

Clayton's Sweetroot (Osmorhiza claytonii)

@KentPfeiffer
I had considered labeling this Clayton's Sweetroot (Osmorhiza claytonii), however after converting to a photocopy format from the original picture, and really blowing up the leaf size on a large computer screen, I didn't feel confident as to their similarities, so I continued to investigate and ran across the wild parsnip leaf. Attached are the photos for you to compare. Appreciate you taking the time to see what I'm dealing with.

This is the Clayton's Sweetroot

Just found another good example of leaf structure and form for Claytons Sweetroot.
