Plant Identification Help Needed

[mythicalgirl]

The previous owner of my house planted a lot of stuff.  Mom and Dad have helped to identify most of them as I am still learning this stuff.  However there is one plant (bush?) that has never been in bloom when they are here and they've been unable to identify at other times of the year. 

So we have pictures!

This is the vegetation in question in bloom:

 

And here is a close up of the flower (and not a bad photo if I do say so myself)


Anyone have any ideas?
