Hi Robert,

My research has T. roxburghii native from India to Maylasia, with
introductions to central east Africa, Brazil and Taiwan. Others that have
replied to me off list, tell me that the bulbs cannot get below 15 degrees C
or they may expire. Do you have a reference for this species from the
Himalayas? I would be very interested!

Due to the high elevations in the Himalayas to which it is native, I think
summer heat will be an issue more than winter cold.

Yes, it will need the dormancy period and will most likely go into that
phase when ready.
