Plants preferred for xeriscaping are cacti.

Xeriscaping is the process of landscaping or gardening, that reduces or eliminates the need for irrigation.
It is promoted in regions that do not have accessible, plentiful, or reliable supplies of fresh water and has gained acceptance in other regions as access to irrigation water has become limited, though it is not limited to such climates. This method of low-water or no-water landscaping is used to reduce the need for irrigation.
