I bought this plant (along with MANY others) in October 2012 from Lowe’s or Wal-Mart in Greenville, Mississippi. I was living at the mansion in Leland at the time. The label said Crassula ‘Springtime’.
When I was doing research for my first Belmont Rooster blog in 2013, I found a few websites that said it was a Crassula rupestris hybrid, including Llifle (Encyclopedia of Living Forms). SO, I labeled my photos Crassula x rupestris ‘Springtime’. Then later, I became acquainted with Margrit Bischofberger, a Crassulaceae expert, she told me to use only Crassula ‘Springtime’ and delete the ”x rupestris”. Her website, the International Crassulaceae Network, says its parentage is Crassula perfoliata var. minor x ? C. rupestris.
SO, I decided to begin with that parentage in mind. This is where the fun part comes with Crassula ‘Springtime’.
First, Crassula perfoliata L. was described by Carl von Linnaeus in Species Plantarum in 1753. There isn’t a whole lot online about this plant. Even the International Crassulaceae Network, Llife (Encyclopedia of Living Forms) and the SucculentGuide.com do not have photos for ID on their website of this species by itself. If you search images, most are photos of Crassula perfoliata var. falcata.
Second, I found out that Crassula perfoliata var. minor (Haw.) G.D.Rowley is a synonym of Crassula perfoliata var. falcata (J.C.Wendl.) Toelken.
SO, that means Crassula perfoliata var. falcata (J.C.Wendl.) Toelken is the correct and accepted scientific infraspecific taxon of Crassula perfoliata. It was first named and described by Hellmut R. Toelken in the Journal of South African Botany in 1975. It was first named and described as Crassula falcata by Johann Christoph Wendland in Botanische Beobachtungen in 1798. SO, for 177 years it was considered a separate species…
The name falcata in Latin means sickle-shaped… The common name for Crassula perfoliata var. falcata is Propeller Plant or Scarlet Paintbrush. I had also bought a plant labeled “Crassula Dudia-Propeller Plant.” I later discovered it was actually Crassula dubia which is NOW a synonym of Crassula cotyledonis. There is a page for that one, too…
For the heck of it, I tried researching Crassula perfoliata var. minor (Haw.) G.D.Rowley… I found it on the original list on The Plant List (2013 version), but its link to Tropicos list just says Crassula perfoliata var. minor G.D. Rowley without the (Haw.). Anyway, that infraspecific name is now a synonym. It was named and described by Gordon Douglas Rowley in Cactus and Succulent Journal of Great Britain in 1978. So, I thought probably Mr. Haworth named it Crassula minor first, but that name is nowhere to be found… Then I went to the Llifle website and found the answer… Mr. Hawworth apparently named it Larochea falcata var. minor and that’s where I hit a dead end (so far). What in the heck is Larochea?
Well, I can go a bit farther back on one stem… Besides Larochea being a genus of plants, it is also a genus of slug-like sea snails. According to the Llifle (Encyclopedia of Living Forms), Larochea falcata is a synonym of Crassula perfoliata var. falcata. Larochea falcata var. minor is a synonym of Crassula perfoliata var. minor (which is a synonym of Crassula perfoliata var. falcata). Larochea perfoliata alba is a synonym of Rochea perfoliata var. alba. Hmmm. Where does that one go? OH, it says it is now a synonym of Crassula perfoliata. What is weird is that photo of the Larochea falcata on Llifle looks like the Propeller Plant, but not like the photo is Crassula perfoliata which it is now a synonym of. They use the same photo for Crassula perfoliata var. falcata. So, shouldn’t Rochea perfoliata var. alba be a synonym of Crassula perfoliata var. falcata since the same photo is used for both?
According to Plants of the World Online by Kew, the above findings are still accurate.
I almost forgot about the possible Crassula rupestris part. Crassula rupestris L.f. is the correct and accepted scientific name for this species of Crassula that is possibly the other parent. It was first described by Carl von Linnaeus in Supplementum Plantarum in 1782. I have no idea what the “f.” is for.
Now I am exhausted! I did bring my Crassula ‘Springtime’ with me when I moved to Missouri. The last photo I have of it was taken on 7-30-13. I am not sure if it died or if it was one of the plants I had to give up in mid-summer 2014. Maybe someday I will try it again…
If you have any comments, questions or suggestions, I would like to hear from you.
