Which plants are best adapted for very dry, hot environments?
Cacti are perhaps the best-known desert plants. They have thick stems that store water, and sparse leaves that minimize evaporation. Some cacti, such as the saguaro, can grow to be over 20 feet tall. Succulents are another type of desert plant that are adapted for water conservation. Cactus and succulents: these plants are well-adapted to arid conditions and can store water in their fleshy tissues, making them highly water-efficient. Quinoa: quinoa is a drought-tolerant crop that requires less water compared to many other grains.
