It’s no wonder many homeowners gardening in arid climates use gravel instead of plants, or opt for artificial turf for a green front yard.

Consider, for example, desert marigold (Baileya multiradiata), a drought-tolerant, foot-tall, blooming groundcover with pretty yellow blossoms atop silvery foliage in spring.
