It looks like a carrot. Could you have dropped some seeds when sowing your vegetable garden? Or had some carrots run to seed? If not a culinary carrot, then something else in that family, Apiaceae.

Or perhaps Daucus carota - Queen Anne's Lace. A common weed.

Domesticated carrots are also Daucus carota so the foliage will look pretty similar. I just thought this one looked a little too ferny for the wild version.

if you break off a piece.. and crush it in your fingers.. it will smell like carrot...

rather common weed around here.. the indians called it the white carrot...

rather pretty flower...

So interesting…..haven’t grown any carrots…..of course bird dispersal is possible. It does smell carrotie…..☺️

So dig it out and examine the root. Orange or white? (Unless of course the seed was from a domesticated non-orange carrot.)

Queen Anne's Lace is a common weed in the midwest US.

No wayward garden carrot seeds are required.
