It rains in the mountains and amazingly enough, we have gotten 5 inches since the first of the year in Reno. Mine look good. I suspect its more of a drainage problem then a watering problem. Like I said, mine are planted in coarse sand. The ones I've seen in the mountains are planted in the seams of decomposing granite in the outcrops.
They are really cool - they seem to cling to any little bit of gravel even growing sideways sometimes. I found a photo of some growing in habitat:
