My lilies

So this year my lilies have been growing so much, so much that they're about as tall as me. I'm guessing I have two to three times the blooms this year vs last. 

They kinda started to fall over. I've staked them every year and they've never needed it, til this year that is...

I just love these, but then I have this bush/tree/thing that I don't know what it is:

It's blooming right now and I don't know what it is. Any ideas? The flowers look like this:

Any info would be helpful! Keep in mind I live up North and this thing gets exposure to the cold. Thanks!
