I went to upload my Crassula ovata to the database, and it got me wondering...
We have 'Gollum', 'Hobbit', 'Ogre Ears', 'Red Horn Tree' all listed in the database as varieties of Crassula ovata. What's the difference between these? If I understand correctly, 'Hobbit' has a less tubular leaf shape and they have a spoonlike depression without completely wrapping around. (Though our database images have multiple specimens showing the tubular leaves.) How do you differentiate between these plants?
