Of course most anything can be planted in a rock wall if you really want to, but what are some of the best cacti and succulents to use in a wall planting? Especially if they can handle cold temperatures down to -12C or so. That really narrows it down... LOL.
At some point my design for the new garden will involve a rock wall planted with succulents.
