The best outdoor plants for Arizona gardens include those that require little water. Native plants fit the bill perfectly, helping prevent erosion, requiring little maintenance and providing valuable sources of food and shelter for wildlife. Before choosing plants, determine what zone you live in; Arizona’s milder mountainous areas offer different challenges than the hot desert floor.
Western Blue Flax
Sporting dozens of dainty 1-to-2 inch, blue or white flowers that bloom in May through July, the drooping branches of this perennial grow up to 3 feet in height. The plant stays green during the entire growing season, making it a desirable plant for gardens and landscapes when other plants start fading. Hardy in zones 3 to 9, this plant thrives in full to partly sunny areas in well-drained soil and requires low-to-moderate water. Wildlife such as deer and birds use the plant as a food source, while smaller birds use the plant for cover.

Bright red or salmon-colored flowers and sword-shaped, grayish-green foliage make this plant from the Agave family an ideal choice for Arizona gardens.

This slow-growing, drought-tolerant plant is easily grown from seed, preferring full sun in well-drained soil. The tubular flowers act as strong attractants for hummingbirds and butterflies.

This perennial vine, also referred to as old man’s beard, features green foliage and clusters of white or cream-colored flowers that bloom from May through August.
