About the Project

The Unique Sonoran Desert

We live in a unique and beautiful region not only of the United States, but of the world. Recognized as one of the most biodiverse deserts of the world, the Sonoran Desert is one of the greatest gifts of living in Arizona. This project focuses on the native plants, the plants that make the Sonoran Desert the special place it is. We work to protect and keep this heritage alive.

The Sonoran Seed Collaborative lives at Tovrea Castle at Carraro Heights, a historic site owned by the City of Phoenix, operated by Tovrea Carraro Society. This is where Arizona Columbine Garden Club volunteers are devoted to caring for and growing out the out.

Take a look at what you can find growing on our Sonoran Seed Collaborative plot on the grounds at Tovrea Castle. The first five priority species we are focusing on are:

Desert Lavender (Hyptis emoryi)


Desert Marigold (Baileya multiradiata)


Bladderpods (Physaria gordonii)


Low Woollygrass (Dasyochloa pulchella)


Sweetbush (Bebbia juncea)

Each of these five species is unique and have strong importance in our desert ecosystems providing a multitude of benefits. Whether for pollinators, animal forage, or as early colonizers in disturbed areas, these plants are much more than just their beautiful blooms!
