TY so much for your help! Any help sorting the entries would be awesome! Clearly all of the plants at the K. daigremontiana entry are not the same plant. Whatever you need to do to make the name correct for K. x h, please do!
K. daigremontiana is a catch-all, not just here, universally wherever plants are discussed in English. I see all kinds of Kalanchoes ID'd as that species in various places. The few reliable pics I've been able to find, such as the one I added from RHS, show that species as having a leaf about half as wide as it is long, distinctly folded in the middle, with a lip where leaf body meets petiole, distinct mottling on leaf reverse, hardly any distance between nodes. I have 20 diff Kalanchoes, but all have been ID'd as something else.
I was just reading an article about Kalanchoes earlier. I'm sure you, and others, can make much more sense of it, and it mentions a few I don't have.
