@mikako6 Well, it's not to be confused with Wild Carrot, aka Queen Anne's Lace, although Eastern Black Swallowtails will. It does have another name--Cow Parsley--but a cow would die if it ate it. Wild Carrot doesn't produce that kind of seed, which will fiercely stick to your clothes. I've done battle with that stuff on an ongoing basis so I know it back'ards & forewards.
