Where Does Arizona Cliffrose Call Home?

This native treasure is found exclusively in Arizona, where it has adapted perfectly to the desert Southwest’s challenging conditions. As a true southwestern native, it’s naturally equipped to handle the intense heat and limited water that characterize this region.

A Word of Caution: Rarity Matters

Here’s the important part: Arizona cliffrose is classified as Endangered in Arizona. This means that while it’s an absolutely gorgeous addition to any native garden, we need to be extra careful about how we source and grow it. If you’re considering adding this beauty to your landscape, please ensure you’re purchasing from reputable nurseries that use responsibly sourced, legally propagated material.

Growing Arizona Cliffrose Successfully

This desert native is surprisingly easy to grow once you understand its needs:
