Hardiness of Pinellia cordata

How hardy is Pinellia cordata? I have a dozen or more little single-leaf
plants sprouting in the gravel of a narrow bed between front walk and
garage.

I grow Pinellia cordata as potted plants. In winter the pots go into an
unheated garage, attached to house where it gets cold but doesn't
freeze. The pots are ignored all winter, hauled out sometime in early
May. Water, and away we go again.

Clearly, last summer little leaf-borne tuberlets (or whatever we want to
name them) fell off the leaves, dropped into the crevices between the
stones - and survived.

I wouldn't have anticipated this happening. So is Pinellia cordata hardy
enough to plant out in my woods? Arisarum proboscideum is hardy, grows
well and seems to increase, if that's any help.
