In this hot landscape , rainfall averages 4 to 8 inches a year, the plants must be tough to survive.
The Chihuahuan and Sonoran Deserts make up much of the landscape here. The Sonoran is divided into a colder portion called the Mojave and an almost frost-free portion called the Lower Colorado Desert.
Each has its own signature or special shrubs and trees.
For example, the Sonoran desert has Saguaro cactus and the Mojave desert has Joshua trees.
The prettiest part of this dry land can be the foothills, where higher elevations mean relatively cooler temperatures.
A natural desert garden is made up of small, native trees such as the willow and the Blue palo verde.
Flowering and evergreen shrubs,
Succulents like cacti and agave.
And an assortment of rainy season flowers and grasses.
Shrubs of the Desert and Southwest can withstand hot, dry conditions. Many have extensive root systems.
Some are considered evergreen while others shed their foliage if needed to conserve energy.
A diverse variety of plants call the desert home and surprisingly, there is ample birds, butterflies and other wildlife that take advantage of it all.
A drip system on a timer or some other water source at dawn and sunsets guaranteed to bring in all the local desert creatures to your Southwestern desert garden.
