Symplocarpus foetidus (closer to bulbous than cardamine)

Yes, there are Cardamine species that have a sort of tuber that easily
qualifies them for geophyte status.

Not all (perennial) plants that die back to some type of rootstock are
geophytes in the botanical or horticultural sense. Papyrus also has a
rhizome as do many other grasses but this does not automatically make them
geophytes, even if they are deciduous. The underground storage organs of
geophytes are more typically a response to a dry pronounced season rather
than cold.

I still like Charles Gorenstein's off-hand definition of a geophyte or
"bulb" in the broad sense: any plant that has a dormant structure that
stands up perfectly well to being tossed in a paper bag and mailed across
the country.
