They don't need a dormant period. However, if you stop watering them,
they
will go dormant. I just dug all of mine this week. I will store them
in
the basement in a box until next spring.

Thanks for the info. So, if I stop watering them, they'll just go
dormant and not die completely?

My apologies for incorrectly posting under this thread.

Yes. They will go dormant. The top will die back, but the rhizome will
survive. Here is a link to some information:
