The two Amoreuxia species grow wild in Arizona in USDA Zone 7 (Sunset Zone 10). They tend to grow where rocks no doubt insulate the tubers from frost. They tolerate water during their winter dormancies just fine in Yuma where there is no frost; winter precipitation is more erratic where they are native.
My plants haven't produced seed in a number of years now. Even when well-watered, actual summer rain is magical, and we haven't had any in quite a while until this year.

I don't know if this is truly a geophyte or not, but it's been in a
BX/SX several times (I received the seeds from one in 2014) so I know
people here grow it.
The seed packet was misplaced and I only found it this past spring, but
based on the appearance I scarified the seeds and 6 of 8 germinated
rather quickly. Three of those faded away over the following few weeks,
but the other three grew well. Over the last couple of weeks the leaves
have yellowed and dropped, and I assume they're entering seasonal dormancy.
I also assume I should reduce water, but avoid desiccation, as with
Cynorkis or Habenaria? How about cold tolerate or preference while
dormant? Surely not hardy in NW Arkansas, so any advice about pot
culture will be appreciated.
