The genus, Phedimus Raf., was named and described by Constantine Samuel Rafinesque in the American Monthly Magazine and Critical Review in 1817.
As of 11-19-21 when this page was last updated, Plants of the World Online by Kew lists 16 species in the Phedimus genus. It is a member of the plant family Crassulaceae with 36 genera. POWO lists 462 species in the Sedum genus… Those numbers could change as updates are made on POWO.
Species in the Phedimus genus have been moved back and forth from Phedimus to Sedum countless times and the controversy probably continues. Keeping up with name changes can get a bit tiring, especially when names change you least expect. Then there are others, like the species of Phedimus, you wonder when they will change again.
I have only grown a few Sedum species and cultivars that have changed to Phedimus. I am not going to go into a lot of detail because there are links below to websites written by experts. I rely on hands-on experience to write about.
You can click on the links below for more information. there just isn’t a lot online about the genus as a whole… You can also click on the plant’s names under the photos which will take you to the pages I have experience with.
I brought this Phedimus kamtschaticus home from a local greenhouse in 2016 unlabeled but I figured out what species it was. It has done very well and has bloomed every year. The species is very easy to grow and has stayed in a small clump. That is a plus is you don’t want it to spread like the Phedimus spurius… It is much hardier than the ‘Variegatum’.
I brought a six-pack of Phedimus kamtschaticus ‘Variegatum’ home from Lowe’s in 2012 when I lived in Mississippi. I put them in a pot and brought them with me when I moved back to the family farm in Missouri in 2013. We have had our ups and downs, but 2019 was its best year and it even flowered. After that, it was downhill again…
I brought this Phedimus spurius ‘Dragon’s Blood’ home from a local greenhouse in 2015. It was unlabeled and I debated calling it ‘Dragon’s Blood’ for several years because I wasn’t sure. Since it needed a proper name and ‘Dragon’s Blood’ has been a pupular cultivar for many years, I decided to go with it. Photos online mostly show this cultivar with maroon leaves, but they aren’t always that way. It depends on the temperature, light, and the season. This “colony” has spread nicely where I put it…
Ummm… To say the Phedimus spurius ‘John Creech’ has done well would be an understatement. To say it has spread would also be an understatement… It has spread from it’s spot to the planter next to it wanting to take over. I guess that is what it was meant to do so I shouldn’t complain that much. Other plants can be moved if necessary or I can fight a losing battle to keep it where I put it in the first place. I brought this cultivar from Green Street Market in Clinton, Missouri in 2017.
That’s all I have for the Phedimus genus at the moment. Never know what I may find to bring home.
