You can have a xeriscape anywhere. All it takes is using plants that need only a little more water than natural rainfall.
We have a lot of areas on campus that are non-irrigated or planted with climate appropriate plants.
This is a newer planting of Agave potatorum used as a ground over in a planter that gets minimal irrigation
I planted these Aloe cameronii and "Blue Elf" about 10 years ago as single stem cuttings. They get no supplemental irrigation, rainwater only.
