Superb La Jolla Landscape

I recently saw this landscape in upscale La Jolla, California.  I really like the way this designer combined the plants!

The groundcover forms a tightly-woven carpet between the articulated succulents that are graphically arranged.
The landscape is terraced, with the upper level highlighted by Cordyline australis 'Red Sensation' underplanted with Senecio mandraliscae. An Equisetum hedge provides a backdrop while screening residences from the street.
The many layers of this landscape come together magically!
