1. Desert sage
Desert sage, or Salvia dorrii, is a herbaceous perennial native to the western United States, namely California and Arizona. Growing in mountainous and dry regions, this plant needs dry, well-draining soil, with plenty of sunshine. Desert sage grows best in US hardiness zone 6 to US hardiness zones 10.
Some of the best desert plants are celebrated for their drought-tolerant properties, and plants with silver foliage, such as desert sage, produce silver-green leaves that helps to reduce water loss.
Many sage plants are classified as California native planting and would be a 'versatile and vibrant addition to any garden,' says Maya Argaman, native plant expert and Horticulture Senior Program Coordinator at the California Native Plant Society.
'Sages offer a wide range of forms, foliage and blossoms that combine well with most other plants in the dry landscape,' Maya adds. And, for those seeking native spring flowers to attract hummingbirds and other pollinators, sage plants are known to be popular with 'hummingbirds, butterflies, and bees, but fortunately, not deer or rabbits,' Maya adds. 'The distinctive fragrance of the foliage repels garden pests.'
2. Agave
For those gardeners seeking drought-tolerant landscaping ideas, agave plants are one of the most structural and striking succulents. Native to desert regions in North and Central America, agave plants grow best in US hardiness zone 7 and above, thriving in dry regions.
These unique plants produce pointed leaves and tall flower spikes, making them iconic symbols of desert landscapes, a must have for those seeking the best desert plants. 'Agaves are easily grown outdoors and in pots,' says Greg Starr, agave expert and owner of Starr Nursery, specializing in cacti and succulent growing. 'The soil should drain excess water quickly,' Greg adds, 'and these plants will need plenty of light.'
'Look out for mealybugs and agave mites,' Greg warns, 'both of which can multiply rather quickly.' Agave mites are 'difficult to eradicate even with treatment,' Greg adds, but infestations are easier to deal with the earlier they are identified, so be sure to check your succulents for signs of damage or pest activity.

Opuntia plants produce large, flat stem segments called cladodes, as seen in the image above, and as with other cacti species, the stems and stem segments are covered in small hair-like spines, so approach with caution.
While not usually grown for their blooms, the beautiful flowers can be yellow, pink, orange or white. The common name refers to the fruit produced by opuntia, referred to as prickly pears, that appear much like red berries atop the stem segments.

Desert mint is native to California, found in forest, mountainous and desert regions. Growing happily in US hardiness zones 5 to 10, this plant can be sustained with little water during spring and summer.
'California mints make wonderful flower border plants,' says Maya Argaman, Californian native plant expert. 'These perennial herbs are low-growing, producing rounded clusters of lilac flowers.
'Not only do mints attract pollinators, their leaves are often fragrant,' Maya adds. 'Mints can be grown in pots or beds, renowned for their drought-tolerance.'
