WESTMINSTER WEST — Wild parsnip is often confused with similar-looking giant hogweed, cow parsnip, Queen Anne's lace, and angelica.
Wild parsnip is the only one with a yellow flower; however, cow parsnip is equally noxious when it comes into contact with the skin, and giant hogweed is considerably worse.
I live where we have a lot of wild parsnip. I encountered it unknowingly several years ago, and did indeed get second-degree burns, with scars that lasted over a year.
