New (to me) Tree

I probably need to try and get a better photo of these trees, but I noticed them for the first time the other day leaving work! They have these itty bitty blossoms on them, in a bright fuchsia color. They're gorgeous! I had never noticed the one in front of my office until this week, and then of course I noticed that I rid the train right past a whole row of them every day. But what are they?!?
