Germinating Desert Calochortus species?

I have grown all of these species, and I germinate all except C. flexuosus 
and C. striatus in the refrigerator in damp vermiculite, putting them in 
ziplock bags.  I start them around October.  Some, like C. kennedyi, 
germinate very rapidly, others like C. ambiguus take up to three months. 
After germination, sow them in a very free draining mix, and cover with 
coarse sand. It's not germinating them that is the problem, it is keeping 
them once germinated.  They all need dry conditions, low humiditity, free 
draining medium, and are still prone to fungal diseases, although you have 
an advantage in Nevada.  They do not like heat.  So, I would sow them in the 
refrigerator, then put your pots outside in very well ventilated conditions, 
not exposed to full sun.

Good luck.
