I live in Riverside, CA -- very hot in the summer and dry in the winter. I have a bank that is terrible clay soil. I need some suggestions other than the Myoporum that I currently have that isn't that happy. Rosemary and a low acacia shrub do well, but I want some other alternative ground covers that are happy and green. Lantana perhaps? Any suggestions appreciated.
