Landscaping in the modern vernacular is done very well by Coen+Partners. They have worked on some outstanding home structures. Their approach is minimal with repetition creating pattern. The second picture with the row of cactus is genius. They have also worked on some great mid century houses. I have always like the use of steel in curbing, planters, and retaining walls. The rusted steel adds a great patina while introducing a new material.
