This plant was named after the ogre's ears in the movie Shrek. The leaves are really cute and unusual. I also have a Crassula ovata 'Hobbit' that looks really similar. For the longest time, I thought they were the same plant.
The leaves of 'Hobbit' are more tube-shaped, sometimes with a little cup at the tip (see photo below). 'Ogre Ears', on the other hand, has a more pronounced, flared, saucer shape at the tip of the leaf. I think they do get mixed up a lot and are often mislabeled. But from what information I can find, they're not even the same species. To make things even more confusing, there's also a variety of Crassula ovata called 'Gollum', which looks exactly like "Hobbit'. If you know more about this, let me know!
Here's the label on the pot for more information:
