Apparently this time it has failed me spectacularly. I don't remember where I purchased this plant, or how long I've had it. It doesn't particularly bother me that I don't have an ID for it now; it does bother me that I don't remember if I ever had an ID for it.
I'm inclined to think that it is an Echeveria or a Graptoveria. The leaves suggest the latter to me, however the flowers are very Echeveria-like.
Three views of the flowers. In form, they look exactly like the flowers of all the other Echeveria varieties I grow, and the color is similar as well.
If anyone knows what this is, I'd be happy and grateful to hear from you. In the meantime, I think I'll have another go at making a spreadsheet to keep track of things.
