Thanks, Baja, for checking. I'm also finding that they're treated as interchangeable. A reliable Website listing more than one cultivar is what we need, but I'm not finding one. I'm mostly finding this type of listing:
http://worldofsucculents.com/e...
Just as in our database, it lists 'Rosea' as the main cultivar name and includes the other two names as alternatives. It also provides a description allowing for no color distinctions for different cultivars: "Branch tips are orange, red, or pink. The color tends to fade closer to yellow in the summer, and becomes redder in the winter."
Please don't hesitate to ask any questions you might have. We all had to learn the ropes here (and are still learning the ropes here).
