Despite its desert climate, many plants thrive in Arizona. In fact, most plants will grow well there that tolerate USDA hardiness zones of 4b to 10b.

Drought-resistant plants in Arizona share characteristics that they enjoy lots of sun and soil that provide excellent drainage. You can grow plants from small shrubs to full-sized trees. Best of all, many drought-resistant plants that grow in Arizona offer beautiful flowers for much of the year.

Bee Brush (Aloysia gratissima)

It’s a shrub that grows up to 12 feet tall and eight feet wide.
