Hi All,
I grow a couple of different Conanthera and I treat them the same. I have them in a sandy mix about 80 sand/20 loam in clay pots. I have them with my South African winter growing bulbs. Cold but never freezing. Completely dry in the summer. They seem to do ok though not blooming size yet.  Our summers here can be very wet so I don't plant too many things in the ground. 
If you are wanting to grow these in the ground outdoors, I guess now, would be a good time to start tracking ground temperature/depth in relation to air temperature/duration indexed to rain/soil moisture levels. All that correlated with day/night cycles with lunar and solar relationships considered. Over a 20 or 30 year period with projections for possible future global warming/cooling trends taken into account.
That would go a long way in determining how viable outdoor planting would be or you could just plant some and see what happens.
