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.
