Waxy coatings to retain water are a common desert adaptation of plants in the Mojave Desert.

In the Mojave Desert, many plants have developed waxy coatings on their leaves and stems as an adaptation to the harsh, dry environment. This waxy layer, called the cuticle, helps reduce water loss by providing a protective barrier against the intense sun and arid conditions. The thick coating minimizes evaporation, allowing plants to conserve precious moisture. This adaptation is crucial for survival in the Mojave, where rainfall is sparse and temperatures can soar. Other adaptations like deep roots and small leaves also help plants thrive in this challenging desert ecosystem.
