Could use some help identifying flowers, and other questions!

I live in an apartment - have been at the same one for about a year - and have noticed various flowers springing up this year (which I didn't plant, obviously). I'm hoping someone can help me identify what they are! First is this adorable blue/purple thing growing in shade along the border of the yard: Next are two plants that were in a semi-cultivated space: (The plants in the background are cherry tomatoes!) The last are some smallish flowers growing along a rock wall in the front lawn: I would also especially like to know if anyone knows the best way to hijack some of these flowers for future gardens...i.e. will these eventually have seeds, or should I divide them, or what? This is the first year I've grown anything, so I may or may not know what you're talking about...but I'm sure I can look it up! Also, is it feasible to grow a mulberry tree from seed? I have a few mulberry trees in the yard and would love to get some babies started so I can eventually plant them.

    in the middle photo the pink flowers are Verbena Boneriensis and the purple/blue are some type of Salvia. Top pic looks like a type of Campanula to me
