Having no luck with desert trunking yuccas except for Elata. I have had luck with this Torreyi growing under a roof overhang and using a lean-to plexi-glass to shield off winter precip. Its about 3 1/2 years old and was a potted 4" cup.


below is a pic of a Y.elata I planted 10 years ago from 3g nursery stock from Albuquerque. Its at my old house and the current owner wants to cut it down. He asked me if I want it but I told him the tap root is too far in the ground now and it would die if the tap root was severed but luckily its still there.
