Well Robert, from the looks of your pictures it'll be no problem. They all look like they are loving the soil and conditions. The raffs especially seem to be enjoying life there. And now I think of all the money I've been wasting on pots!
No, I don't have your soil conditions, unfortunately. Is this a fenced in area? I'd be scared of an dog or unaware person running through and snapping off a plant! Keep posting results please, you may convince me to try a few yet!
