Sedum stenopetalum, also known as wormleaf stonecrop or narrow-petaled stonecrop, is a species of flowering plant in the stonecrop family. It is native to western North America from British Columbia and Alberta to northern California to Wyoming. It can be found in many types of rocky habitat, such as cliffs, talus, and steep ridges.{{Cite book|last=Taylor|first=Ronald J.|url=https://www.worldcat.org/oclc/25708726|title=Sagebrush Country: A Wildflower Sanctuary|publisher=Mountain Press Pub.

=Subspecies and varieties=

The species has two accepted subspecies and one accepted variety.

==''Sedum stenopetalum'' subsp. ''ciliosum''==

Subspecies ciliosum was first described by Thomas Jefferson Howell as a species named Sedum ciliosum in 1898. It was reclassified as a subspecies by Robert Theodore Clausen in 1948. It only grows in the state of Oregon.{{cite POWO |id=231887-2 |title=Sedum stenopetalum subsp. ciliosum (Howell) R.T.Clausen |access-date=21 December 2024}}

==''Sedum stenopetalum'' var. ''monanthum''==

Variety monanthum was initially described as a species in 1898 by Thomas Howell, but with the illegitimate name Sedum uniflorum. It was then described by Wilhelm Nikolaus Suksdorf in 1927, again as a species, but this time with the name Sedum monanthum. It was reclassified as a variety of Sedum stenopetalum under its present name by Hideaki Ohba in 2007.{{cite POWO |id=60447838-2 |title=Sedum stenopetalum var. monanthum (Suksd.) H.Ohba |access-date=21 December 2024}}

==''Sedum stenopetalum'' subsp. ''stenopetalum''==

The autonymic subspecies grows in western Canada and the northwestern United States.{{cite POWO |id=231892-2 |title=Sedum stenopetalum subsp. stenopetalum |access-date=21 December 2024}}
