What are these lovelies growing in my yard?

We bought our house last summer and by the time we moved, painted and settled in, basically everything in our yard had already done it's thing and we figured we'd wait until this spring to start doing the guessing game as to what was growing around the property. These are some pretty flowering somethings I have in my backyard. One is a bush, one a tree and then the little plant thing I have no clue if it's a planting or a weed. Can anyone help me out?

The tree has these wonderful, rich magenta colored flowers with burgundy leaves.


This bush has teeny tiny little white flowers cascading down the branches. My mother thinks it "bridal" something or "wedding" something but can't recall.



And this- bee balm? It's the only thing that even remotely comes across my mind when I look at it but I don't think they grow in quite such a clump do they?...
