Found in my garden in Portland. It was in the herb are and I scattered a bunch of miscellaneous seeds there, but nothing that quite looks like this. It survived the winter — I noticed it last year. I assumed it was parsley and have been eating occasional sprigs of it — there is a slight bitterness but not unpleasant, and I have had no ill effects. After I realized it is not parsley, I stopped eating it and did try to pull it up. Very hard to uproot! Pictures are of the leaves, the center stems, and the “stump” left after I pulled up the greenery (my best attempt to uproot/eradicate it.)
