I had a Sans in Virginia for a very long time (~3 years) who neither grew, nor died. We had a love-hate relationship. I asked myself, why have I been dragging this loser of a plant around for so long? And why have I dragged it down to FL? Well, once it hit the warm outdoors and got some REAL UV rays, this plant sent out a gazillion little shoots and is now in the ground, and has tripled in diameter in less than a year. There's a 3 year dormancy for ya, talk about confounding the rules!
Here's a link I found that explains some drought adaptations...I think understanding these helps us cultivate our succulents better.
