The flora of the Sonoran Desert is resilient mainly due to its ability to store water in various parts of the plant, such as stems or leaves, enabling them to survive long dry periods.

The plants in the Sonoran Desert have evolved unique adaptations to thrive in one of the driest climates on Earth. Many desert plants, like cacti, store large amounts of water in their tissues, which helps them endure prolonged droughts. This water storage capacity allows them to survive the extreme temperature fluctuations and dry periods typical of the desert. Additionally, some plants have evolved to minimize water loss by having waxy coatings or reducing the surface area of their leaves, further aiding in their survival.
