This is not as simple as it looks. It is something of a guessing game for me. I am rather certain that #1 and #2 are identified correctly. I am not so certain about #3 and #5. The name of #4 is merely a guess. #6 is the only one that I know the name of for certain, although the name that I know it as is now outdated.
The lack of a species name for the two species of Sedum #1 and #2 seems like a cop out to me. I might have discussed it in one of my Wednesday rants, or will do so soon enough. All species should be described as a ‘species’, not merely as a genus with a cultivar name tossed in as if it adequately designates the identity. I sometimes write about how the nomenclature of plants is like that of cars. Both plants and cars are distinguished by genus AND species, with some specie divided into separate cultivars and varieties. (Cultivars are merely ‘cultivated varieties’.) Depriving a plant of a species name is like describing a car as a Buick ‘Convertible’, or a Chrysler ‘Sedan’. There is a big difference between a convertible Electra and a convertible Skylark, although both are Buicks. There is also a big difference between an Imperial sedan and a LeBaron sedan, although both are Chryslers. I may not have identified the two Sedum with their correct names, but even their correct names are not very correct anyway.
Echeveria glauca #3 seems too simple. Shouldn’t it have a cultivar name too? I really do not know. I really do not even know what species it is.
The same goes for Graptopetalum paraguayense #4. Really, I do not even know what genus it is. This is merely a guess. How embarrassing.
Aloe brevifolia #5 has a different issue with its name. It seems that all aloes are known simply as Aloe vera, even though not many of us would recognize Aloe vera if we actually saw it. This makes it easier to identify unknown aloes, but complicates the identification of familiar aloes.
Then there is the easily identifiable Bulbine caulescens #6. Seriously, I recognize it, but somehow, the name got changed. The first name is how I know it. The second name is the newer correct name.
1. Sedum ‘Angelina’
2. Sedum ‘Blue Spruce’
3. Echeveria glauca
4. Graptopetalum paraguayense
5. Aloe brevifolia
6. Bulbine caulescens or Bulbine frutescens

Your Aloe brevifolia looks like an aloe I grow ( A. Jucunda)
I don’ see many differences with mine in your close up. No idea for others

Aloe jucunda is smaller with more flaring rosettes. However, it is so uncommon now that I would not recognize it if I saw it. I would never know if ours was the same.

Yes, I have grown a few different aloes that were all labeled as Aloe vera. One of them is Aloe arborescens, I do not know what the others are. The good news is that some work just as well herbaly as Aloe vera does.

Your pictures are perfect! Love the closeups – especially #3.

Thank you. I happen to like #6, but only because I know what it is, and it happens to be an important species to me. I know the picture is not as close up and pretty as the others.

Tony, I also find it difficult to identify some of my succulents. The succulent you identified as Graptopetalum paraguayense, does yours have trailing rosettes? the picture does not provide enough information

Yes, there are trailing rosettes, but they curve upward and defoliate so that lower few inched of each stem is somewhat bare. pups develop at the base of the bare section, where the stem curves.

Your photos really bring out the beauty in these succulents, regardless of their name. Why sort of camera do you use, Tony? Is it auto focus or do you use lenses?

You know, I do not know what the camera is. It is not here right now. It is in the pocket of a jacket that I wear at work. It was inexpensive. It focuses itself. It sometimes had difficulty deciding on what to focus on. Otherwise, it takes all my pictures.
