Solved ID confirmation please

I was givem these but the label has faded, I can just make out the word 'yellow' in one of them. I think it's probably Cephalaria gigantea. Any other suggestions please?

 

The leaves look right but the flowers will be more creamy than yellow if it's the right plant. Lovely plant to have.

 

I agree it is Cephalaria gigantea. 2 m tall when it flowers, lemon yellow.

 

Thanks Obelix

 

Thanks Asarum

 

Cephalaria gigantea. ..common name giant scabious or yellow scabious.
Super plant...wish I had room for one.

 

Thanks Silver Surfer, I thought they were but lost confidence just before I planted them
