Very similar in appearance to the deadly poison hemlock, Daucus carota is distinguished by a mix of bi-pinnate and tri-pinnate leaves, fine hairs on its stems and leaves, a root that smells like carrots, and occasionally a single dark red flower in its center.
I've taken both into the office of the local public school because they had Conium maculatum growing at the edge of the school "eco-pond" (no, I'm not kidding). The pond is right next to a 40' tall stand of dog-haired fir (trees less than a foot apart) with a sign in front of it indicating the level of weather-related fire risk.
It's a wonder those kids learn anything in such a place.
BTW, the easy way to control hemlock is to trim the flowers.
Please don't read to much into it because I suppose my reason was just as obscure as your reason for asking me why.
I scrolled down to see if anyone had looked at Wikipedia and additionally saw there was no comparison to Queen Anne's Lace.
I thought others may like to see the botanical names together.
