Plant ID please?

I bought this about 4 years ago for 50p on the dead trolley in the local GC because I like the leaf. It was unlabelled. Can anyone tell me what it is? It's never shown any inclination to flower, appears to be completely hardy. I need to tidy up the old yellow leaves but hopefully you can see the silvery new leaves in the centre.

Ooh that's the bunny
Thanks Hosta.
Half my garden's come from the dead trolley. Some survive, a few don't but it's worth the gamble a lot of the time
