    Answer

    Dear gardenkilter, good afternoon. I can't tell you for certain which species this is: Cardamine diphylla or C. maxima. The details I need are not present in the photograph. If you use the taxon page for Cardamine maxima on Go Botany, it will tell you how to distinguish this species from Cardamine diphylla. If you can get a close-up image of the leaf margin or an image of the rhizome (which you don't have to completely unearth), I could help more. Good luck.
