Looks like I lucked out by not trying to mimic its local conditions. I grow it with all my other mediterranean type bulbs (like those from Chile or the Cape Province of South Africa). Since Southern California has a very similar climate (especially to Chile), that means I keep it in a shaded and completely dry area all summer long during dormancy. Then in the late fall when the first rains return, I pull the pot it’s in out of storage and set it unprotected out in the open, where it gets any winter rains plus additional watering if it doesn’t rain for a long while. A few nights each winter, the night-time temperature can drop close to freezing and sometime a degree or two lower just before sunrise. When the air is moist, there will be frost when the temperature gets close to freezing.

However, I just looked up the native conditions. They are from the Antofagasta region, Region II, of Chile which is in the far north. The grow at low elevation near the coast. According to Wikipedia and Chileflora:

The climate is extremely arid albeit somewhat milder near the coast. Nearly all of the region is devoid of vegetation except close to the Loa River or at oases. The average rainfall in the Antofagasta is just 1 millimetre (0.04 in) per year. From the coast, east to the Chilean Coast Range, is the south-central part of the Atacama Desert, the driest desert in the world.

T. philippians grows exposed, but with protection from direct sun through coastal fog. There is coastal fog, called camanchaca: The plants obtain water mainly from condensation.

I haven’t done anything else special to care for it.
