pls identify this leafless bush

[Anisa]

The amount of knowledge of this forum members is amazing. Time after time i see some weird plants being identified and weird cases solved. Well now i need a help with mine.
I have these bushes growing along a wall and I am planing to dig them out, list them on craigslist for free, and replace with boxwood, but the thing is that i dont know their name. As you see from pic - they barely have any leaves right now. They usually get leaves later in summer and the leaves get dark red after frosts and stay way into fall. It also flowers in late summer with a cluster of small purple/lilac blossoms. I dont know much else besides that apparently they are hardy in zone 6b (Kansas, Olathe, where I live)
Could you please identify them for me, so I can give them away... or perhaps someone that lives close wants them?? I also have 2 bushes of holly that need to find a good home.
Thanks!
