Sedum glaucophyllum

SEE-dum   glaw-koh-FIL-um

Sedum glaucophyllum R.T.Clausen is the correct and accepted scientific name for this species of Sedum. It was named and described by Robert Theodore Clausen in the Cactus and Succulent Journal in 1946.

The genus, Sedum L., was named and described as such by Carl von Linnaeus in the first edition of Species Plantarum in 1753. Plants of the World Online currently list 456 accepted species when I am updating this page on 1-4-20. There were 550 accepted species when I last updated on June 8, 2019, when I am updating this page. Version 1.1 of The Plant List (not maintained since 2013) listed 392 accepted species plus 29 infraspecific names, a total of 655 synonyms, and 429 names yet to be assessed. The number of accepted species will continue to change. There are other databases but I think Plants of the World Online by Kew is the most up-to-date.

When I was in contact with Margrit Bischofberger of the International Crassulaceae Network, she told me she didn’t think this plant was a Sedum glaucophyllum. 

 

Distinctively Sedum glaucophyllum flowers on 4-15-12, #86-66.

I bought this AWESOME Sedum glaucophyllum from Lowe’s in Greenville, Mississippi in the spring of 2012 while living at the mansion in Leland. It did very well for several months then somehow just fizzled out.

Sedum glaucophyllum is native of the Appalachian Mountains from West Virginia, Maryland, Virginia and North Carolina. The description on the Wikipedia says the leaves are “glaucous green, succulent, rounded, long and wide, arranged in a dense helix on the stems. The flowers are white, with five slender, pointed petals…” Ummm, that does NOT describe this plant. 

USEFUL INFORMATION:
Family: Crassulaceae
Origin: West Virginia, Maryland, Virginia and North Carolina, USA
Zones: USDA Zones 5a-9b (-20 to 25° F)
Size: 6” to 8” tall
Light: Sun to part shade
Soil: Well-drained
Water: Average water needs

Growing the Sedum glaucophyllum was somewhat interesting because I had not had any die on me up to that point. I realize now that the Sedum genus is very large and native to many parts of the world and many have different requirements. What caused this plant to die in Leland, Mississippi? Probably the heat and humidity in the middle of the summer.

All Sedum I am familiar with need well-draining soil and should not be in any low areas where water may not drain well. Try planting them in a raised bed or an area that is elevated. They do well in planters where their stems can trail over the sides. This species is not one that really needs to be brought inside for the winter, but they may do OK in a sunroom or greenhouse.

They need bright light but this species seems to prefer light shade. Mine was growing in the corner bed behind the den where it received ample morning sun and afternoon shade. Light shade is also good where they are planted under trees that have been limbed high. Dappled shade like some trees provide is also good. If you know how to communicate with your plants, they will let you know when they need a change.

They are drought tolerant but appreciate regular watering during the growing period. In many areas, they will receive spring rains, but in the summer, as with most perennials and annuals, they need supplemental water. As temperatures start to get cooler and day length decreases, you should stop watering.

Maybe someday I will run into another Sedum glaucophyllum to try. If you have had experience with this plant, or have had one with similar leaves, I would like to hear from you. If you have any other ideas what species this could be besides Sedum glaucophyllum, I would ESPECIALLY like to hear from you.
