Like the garden. When you say rock mulch, you mean little rock pebbles which go directly over amended soil without weed cover? Why not use mulch? Do you think it is alright to group succulents with lavenders, sages, rosemary, ceanothus,or carpet roses with the same drip irrigation plan?

can the South African elephant bush grow to a tall hedge ie. 12 ft, if you let it in so cal? If so, do you know the rate of growth. I am trying to find a drought tolerant privacy hedge (don't want bamboo).
