A Guide to Thriving Plants in Arizona’s Heat

As temperatures in Maricopa rise, the prospect of enhancing local gardens excites many residents. Surprisingly, a range of plants flourish under these scorching conditions while utilizing minimal water resources.

Native Arizona plants offer numerous benefits, including drought tolerance and the attraction of local wildlife such as hummingbirds and butterflies. Contrary to popular belief, gardening doesn’t have to be limited to cacti and succulents. Choosing mature plants ensures they have endured the region’s extreme temperatures, as younger plants might struggle during lengthy summers.

For those looking to brighten their gardens this month, consider these stunning options:

• Annuals: Arizona and Mexican gold poppy, sunflower, verbena
• Cacti and Succulents: Agave, jumping cholla, hedgehog cactus, and saguaro. Note that saguaros grow exceptionally slow—about 1½ inches in ten years!
• Flowers and Small Shrubs: Angelita daisy, Arizona milkweed (a favorite of monarch butterflies), desert globemallow, and firecracker penstemon
• Large Shrubs: Bougainvillea, brittlebush, and creosote bush, which can live up to 1,000 years
• Ornamental Grasses: Bull grass and deer grass
• Trees: Desert ironwood, desert willow, and the Palo Verde, Arizona’s state tree

This list merely scratches the surface of what can thrive in local gardens. As you explore options, keep in mind that the USDA Hardiness Zone for this region is 9b. Research potential plants, considering their mature size, color, and specific environmental needs such as sunlight and water access.

A diverse garden can enhance visual interest and cater to varying bloom times and watering requirements. Strategically plan plant placement based on compass direction and irrigation accessibility. Your garden is an opportunity for personal expression—just ensure your selections can withstand the heat.

In conclusion, choose plants that are resilient in these conditions. After all, just like us, if they experience excessive heat, they might suffer.
