Unknown ? Shrub - Greensboro Arboretum 3/9/2015

Despite the winter weather, I did find some different images at the Greensboro Arboretum in March.  I have no idea why this shrub has red branches sticking out of a trunk that has been cut off.  There were no labels present. I took the image with Camera Plus and edited it in the same app.  I used clarify and it made the branches a more vibrant red.   It will be interesting to see what happens this spring and summer.
