Here's the first one - sorry for the bad pictures. They're between a foot and two feet tall, and I'm thinking it's some variety of campanula. Any opinions?
This horrible picture was just for the leaf/plant structure:
This is the one that is really making me nuts. It's not in bloom yet, but I need to plan where to move it, and I don't know what it wants! You can see the flower spikes just starting to form. It gets a long, droopy spike of teeny tiny white flowers - very pretty. I can post new pictures once one blooms if we come up empty. Also about a foot to two feet tall.
