Olsynium douglasii winter treatment

Hello bulb experts,

I acquired a few forms of Olsynium dousglasii this spring, all originally
from the Columbia gorge region. They went dormant in late June, and I kept
them in the shade and most mostly dry for the rest of the summer, with just
a very occasional splash of water—same treatment I use for my
summer-dormant Tropaeolums. The Tropaeolums are already showing signs of
life. The Olsyniums look healthy (small buds atop little clusters of
healthy looking roots), but I don’t expect them to break dormancy until
late winter.

My question is: do any of you grow Olsynium douglasii in pots? What do you
do with the plants over the winter? The Columbia gorge is wettest in the
winter, but I hesitate to let them get too wet in their pots while they’re
dormant. I have lost things in the past though from desiccation during
dormancy as well. Curious what works (or didn’t work) for others?

Thanks in advance for your advice!
