Why Choose Drought Tolerant Landscaping?
Drought-tolerant plants survive long periods of drought by storing water internally or by developing extensive root systems that sink deep into the soil. Many drought-tolerant plants have additional protection through a waxy coating that reduces evaporation or hairs on the leaf surface, which reflects some of the light thereby insulating the plant. Most plants that tolerate drought use several of these features to survive on low amounts of precipitation. Native plants often are considered more drought tolerant than exotic landscape plants. However, there are also many exotic plants adapted to use in the xeriscape environment. The use of drought-tolerant plants will reduce time and money spent on irrigation. Many of these plants are also tolerant of poor to average soils. Some even prefer poor soils.
