Trio of whatzits

Last weekend I took advantage of a short reprieve from the rain to snap a boat load of photos. One result is a number of "weed or not weed" portraits. When answers are available, posted they shall be.

Answers: Specimen # 1 was probably a weed, and grew so tall it began tangling with my fuchia, so I yanked it. Very shallow roots. Specimen # 2 could be sweet woodruff, but doesn't have the strong scent that the internet describes. And, specimen # 3 is probably not poison ivy. I don't have a rash, but that doesn't really prove anything because haven't been formally introduced before. So, either it's poison ivy and I'm resistant, or it's box elder.
