Umm. Not much to go on. Take another pic in a few weeks. What did you sow?

not sure about your first one, http://i205.photobucket.com/albums/bb226/altavek/IMG_0002.jpg but it's definitely a succulent and it definitely needs more light and probably less water. -ming

I agree with FM on 1 and 3 but think that 2 is an aster, what used to be called Aster cordifolius , but is now called Symphyotrichum cordifolium AKA heart-leafed aster AKA wood aster. It's a common wild plant here in New England that blooms with a froth of pale purple/blue/white in the fall and then seeds around everwhere. Easiest to pull up when still young.

Thanks. I'm having difficulty adding the picture. When I hit the photo icon to upload nothing happens! Help.
