Hi, Just bought our first home and there seems to be P.I. everywhere. I had a terrible rash for a couple weeks after my first day of some pruining some forsythia nearby. There is a 3 leaf vine growing on most of the trees behind the house and I didn't think it was PI until I got the bad rash but after I decided it was PI, I noticed berry-looking groups on the vine in places. The berry-like clumps only appear on the vine growing up the trees. The first image is this up close while the second is a wider shot of the vine. The 3rd and 4th, 5th, and 6th are areas of the ground between these trees where it seems to have PI mixed in with the other green plants and vines, etc. It would be a huge help if I knew for sure if it was all PI. Thank you so much for your help. Your website is great ! These pix are from Connecticut and are near the edge of the woods where they meet the lawn. You have my permission to use these pictures however you like and they are my pictures that I took so no copywright issues. I hope I didn't send too many. Thank's again.
