I had a very large,steep, granite hard slope in Valencia. We planted sprigs of Rosemary. It took forever to grow in, we used very little water, but I liked it. It does attract bees. My neighbor planted Ice Plant, grew faster, took more water, and half the time it had a disease and looked terrible. I trimmed the Rosemary every few years with a hedge trimmer to keep it low. It is great to use with the BBQ. I would use that netting and then plant whatever you do.
