The plant is common in the canyons of the southwestern mountains. It is related 

 to S. neomexicana, but has smaller flowers and pubescent instead of glabrous branches. 

 In habit the two are dissimilar, for S. neomexicana has usually a well-developed trunk 

 with branches, while 5. vestita consists of a clump of mostly simple shoots.
