giant purple hostas?

[Guglielmo Portas]

I was driving by a house with a deeply shaded front lawn and saw a variety of hostas/ferns/etc. One plant stood out- it looked like a giant hosta but with more rounded deep purple leaves. Could anyone suggest what this plant is?

TIA

I bet it was a Canna.

One of the colorful cultivars of Bergenia cordifolia or B. purpurascens?

Thanks for the guesses. What the heck- I drove back over there and knocked on the door. It was ligularia.
