If California intends to aim for a zero-scape (drought tolerant) landscape for conserving water, the plants that should be included are C4 and CAM plants. The C4 plants comprise maize, sugarcane, and sorghum while the CAM plants constitute the cacti, orchids, and euphorbias. The C3 plants tend to lose more water since the stomata remain open. Both C4 and CAM photosynthesis are adapted to dry environments because they are more effective at conserving water. CAM plants may also "idle," which helps them conserve water and energy during times of adversity. In contrast to C3 plants, CAM plants fix CO2 at night when their stomata are open. They also have distinct leaf structures.
