Last year I found a specimen (actually a small group) of Sanguinaria with larger leaves than typical. It was already with seeds and was offered as: Sanguinaria canadensis – large leaf form. I promised I would have pictures with flowers this spring.
Here they are and congratulations to those who bought seeds last year! There is more to it than the big leaves: the buds show up in a nice dusky pink colour, which then fades when the flowers open. Beautiful.
