I got a horrible itchy rash from this when I was pregnant. It keeps popping up all over my yard. In the upper right you can see that it was about to sprout some yellow flowers. It looks like no poison ivy I can find pictures of. I am located in Columbus, Ohio. You have my permission to post these pictures, I used gloves and dug this up myself today and compiled this jpeg for you. Thanks for any info on this nasty thing!
