ID Help Needed

ID Help Needed

So, sometimes you clear out a weed patch and find something interesting. Unfortunately, I can't ID any of these guys I let live. If anyone can help, it would be most appreciated. I'm in Northern NJ, zone 6b: Image hosted by Photobucket.com This one I've let grow for a few years. It was in a very very shady spot. I thought it was lilac that needed some sun to pop some flowers, but when I was transplanting it to a new spot - where I could actually see it - I noticed some teeny pink flowers on it, which have since died. It also has been droopy, which could be transplant shock, but it seems to perk up at night, so it may be that where I found it growing is what it likes. Where it is now gets part sun during the day, and that's when it seems to really look saggy. Image hosted by Photobucket.com Found this one growing by my fence line today, on a patch I was clearing weeds out of. I brought it in a little from the fence line. Very interesting shade of green to its leaves in person. Very attractive. No idea what it is. Growing in a mostly shady spot, although it does get some sun. Image hosted by Photobucket.com This is a bit blurry, so I apologize. Once again, found in a shady spot. This one I found just a couple of days ago, and I left it where it was growing.
