10 Best Plants for the Southwestern Landscape

A few weeks ago, I was asked by one of my editors to come up with a list of the top 10 plants that every resident of the Southwest should consider adding to their Southwestern landscape.

I must admit that the task was a bit daunting at first – not because I couldn’t think of enough plants.  The problem was that my list was much larger.

How Easy is it to Find Native Southwestern Landscape Plants at a Local Nursery?  

I had to pare my list down and decided to focus on plants that would grow in zones 7 – 10, which cover much of the desert Southwest.  In addition, they had to be low-maintenance, native, beautiful and easy to grow.

After considering all of the criteria, I still had about 20 plants.  So, I added one other criteria of my own – how easy is it to find at your local nursery?  

At the end, I had 10 plants that I was very happy with – but I could have easily added a lot more 😉  

I hope you enjoy reading through this list of 10 essential plants for the desert Southwest.    

Flourishing Amidst Adversity: 10 Resilient Plants in the Southwestern Landscape

The desert Southwest is a region of extremes, with scorching summer heat and chilling winter temperatures that challenge even the most robust flora. Yet, in the face of such harsh conditions, these native plants not only survive but thrive. Equipped with remarkable adaptations, these tenacious species call the arid landscapes of the U.S. Southwest their home.

Enduring the relentless dry heat and enduring the freezing winter cold, they serve as a testament to nature’s resilience.

Embracing the Sun: Essential Care Tips for Desert Native Plants

To cultivate a thriving desert garden, sunlight is key. Native desert plants require full sun, although some tolerate partial shade for a portion of the day. Optimal growth is achieved through deep, infrequent watering and well-drained soil.

Allow water to penetrate down to 1½ to 2 feet deep, ensuring the soil dries out before rewatering. For irrigation efficiency, drip systems are recommended. While new plants need more water until established, these desert natives rarely require additional fertilization.
