Sedum adolphii Raym.-Hamet is the correct and accepted name for this species of Sedum. It was named and described by Raymond-Hamet in Notizblatt des Botanischen Gartens und Museums zu Berlin in 1912.
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.
I brought this Sedum adolphii ‘Firestorm’ home from Lowe’s on July 10, 2018. I have heard about this cultivar for several years and was glad to find it. Sedum adolphii has always done well for me, inside and out, and I am certain ‘Firestorm’ will do equally as well.
It was in a small 4 oz. pot when I bought it so I transplanted it into a larger pot on July 29. The label says:
“Drought tolerant when established. Needs well-draining soil. Water thoroughly when soil is dry to the touch. Protect from frost to prevent possible scarring. Looks best with regular watering in hotter months.”
Origin: The species is a native of Mexico
Zones: USDA Zones 9-11 (20 to 40° F)
Size: 6-12” tall
Light: Sun to light shade
*Soil: Well-drained. Potting soil amended with pumice or perlite and chicken grit.
Water: Average. Water regularly during the growing period, barely in the winter.
*There are a lot of potting soil recipes online and many people develop their own with experience and what is readily available. Read the ingredients on the bag and always start with a base of a reliable brand name potting soil. I always use either Miracle Grow or Schultz Potting soil because I can buy it in large bags. They also offer cactus soil in smaller bags with similar ingredients. I used 2 parts potting soil with 1 part additional pumice and 1 part chicken grit. After reading that cactus and succulent enthusiasts were recommending pumice in place of perlite and grit, I decided to try. So, since late in 2018 I purchased a bag of pumice online from General Pumice. I have been using a combination of about 50% potting soil and 50% pumice with favorable results.
Soil-All Sedums require well-draining soil. Sedum grown in pots can be placed in potting soil that you may want to amend with pumice or additional perlite and chicken grit.
Light-Sedums do very well in full sun to light shade. Some even do just fine in more shade. My Sedum adolphii ‘Firestorm’ spends its summers on the front porch where is gets light shade most of the day and a good amount of sun in the afternoon.
Water-I always give my cactus and succulents water at the same time as the other potted plants although I usually just lightly go over them. I only water them once in a while when they are inside for the winter. The Sedum adolphii and now this one as well have been the only two Sedum overwintering in the house since I have been back in Missouri. The other Sedum species I have grown didn’t do well inside.
Propagation-Sedum are easily propagated leaf and stem cutting and by division. Leaf and stem cuttings should be allowed to scab over for a few days before inserting into the soil.
The Sedum adolphii ‘Firestorm’ made it through the winter in the house and now is ready for the great outdoors for 2019.
Sedum adolphii ‘Firestorm’ still looking good and growing on June 16. I was fairly busy over the summer but the cactus and succulents did fine with a little neglect.
I had to move the potted plants inside for the winter on October 11 because an “F” was in the forecast. I always photograph the plants as I bring them inside and measure the cactus and some of the succulents. The Sedum adolphii ‘Firestorm’ did very well over the summer and grew quite a bit. I think next summer I will put both this plant and the other Sedum adolphii on the back porch where they will get more sun.
I will continue adding more photos and information as time goes by.
