I am going to try to do 29 shots of my milkweed plants - not 30 because I used April 1st for my rainbow-calendar. I have a few (almost totally eaten) in my backyard and 3 small ones at the side of my house. You can tell that this picture is taken at the side of my house because of the bricks. Monarch caterpillars only eat milkweed and I have had a lot of caterpillars recently!
