Shrub

I have forgotten what this shrub is called, I am sure it begins with a C. I spotted it out on my short walk this afternoon after successfully managing to get my parcel returned which I failed to do last week. A damp misty day. I have had no luck catching any of the mice in my garden, they are not falling for my trap despite being baited with cheese. The plan is to move them ( at least two but bound to be more) to a spot away from my garden but I have to catch them first. They live on the seed that is flicked out by the birds on the seed feeder,
