I just planted a unrooted cutting from Palmbob,here in the bay area. And to my pleasant surprise it seems to have rooted fast right in ground. I had it over the winter and it had curved a bit..already its becoming upright again.
It also seemed more cold tolerant then it looks. If you like blue cacti..this is one you want.
