Adaptations of desert plants are the morphological and behavioral responses of flora to maximize their chances of survival in arid regions. The impression that the desert environment is hostile is strictly an outsiders viewpoint. Adaptation enables indigenous organisms not merely to survive here, but to thrive. Furthermore, specialized adaptations often result in a requirement for the seasonal drought and heat. For example, the saguaro, well adapted to its subtropical desert habitat, cannot survive in a rainforest or in any other biome, not even a cold desert. In these other places it would rot, freeze, or be shaded out by faster growing plants.

Aridity is the majorand almost the onlyenvironmental factor that defines a desert, and it is this functional water deficit that serves as the primary limitation to which desert organisms must adapt. Desert plants survive the long rainless periods with three main adaptive strategies: succulence, drought tolerance, and drought evasion. Each of ...more
