It is native to the Mojave, Chihuahuan, and Sonoran Deserts of North America. It has been reported from the states of Arizona, California, Nevada, Baja California, Chihuahua, and Sonora.[1]
Description
    
The species is a shrub that grows up to 1–2 metres (3.3–6.6 ft) tall. It is intricately divided into thorn-tipped branches lined with clusters of small, deciduous, gray-green leaves no longer than about 1.5 centimeters. The inflorescence bears a single flower, which has 5 white to purple-tinged petals about a centimeter long and narrowing to claws at their bases.[1]
Uses
    
Ragged rockflower is occasionally used as an ornamental plant in habitat gardens and natural landscaping. It can be grown from seed in well-drained soil for a desert butterfly garden. It is a difficult plant for the average homeowner to grow, as over-watering will kill it.[2]
