My son mentioned that he has seen an example of permaculture down in Santa Barbara which uses rocks piled up, and the plants all grow coming out the cracks between the rocks. This sounds very appealing to me, since I have areas in my yard here in surburbia that could do with rock berms and some food crops, and I have mossy rocks I need to move and do something useful with. So maybe I could pile up some old redwood boards and my abundant oak leaves and build a rocky structure? Anyone know of this technique and what it is called?
