(The photo is from internet, not the actual shrub). Most of the top has been cut off, but it has lots of roots and grows back quite quickly in my experience. I think it's Euonymous fortunei. Variegated yellow/green. Roots the width of a dustbin, with a stumpy stem and some leaves - won't look great this year but may do by next!. The shrub was about 3ft high but then went wild and we had to cut it right back to remove it, as we don't want it where it was.
Please say when you can collect. We're off the Guarlford Road. You'll need to bring a container to put it in, maybe a builders sack or similar, or wrap the root in a tarp.
