Bishop's Children

This is one of the 'Bishop's Children' dahlias I took home when I finished my RHS course.

I know this cultivar well because it was on one of our first plant identification tests. 

All the others are red, this is the only pink one. I probably wouldn't have chosen it if I'd known it was going to be pink as I'm not a big fan of pink but it's found it's way to my plot so I've got to keep it now!
