One of the interesting things about this hybrid is that it is sometimes monocarpic.
If you look at the main stem of this individual, you will see it has elongated much more recently than it was growing previously, and that's not due to low light. This plant is in full sun. The goose neck is because the main stem of the plant has converted into an inflorescence (and branched abundantly at the base, leaving many heads to survive afterwards). That inflorescence has branched at the tip (a couple branches visible in the photo).
This behavior is very wrong for an Echeveria. The first time I saw it, I didn't believe it was real. But now the second or third time, I have been documenting the whole process from start to finish. Some small fraction of the time (around 10-20% in my experience) this hybrid does not flower from the leaf axils, but the growth center.
I am not concerned about the aftermath of this flowering event because stumps left after amputation tend to branch in great abundance (top of main stem still visible in photo):
