I already did a reverse image search and came up with "ogre ears" as a name for this plant. However, this name is associated with other plants: Crassula argentea and Crassula ovata. What is the scientific name of this plant?
This (lovely) succulent is Crassula ovata variety "Gollum", known also as "gollum jade" or "finger jade". Search for the name and you'll find lots of commercial sources. One informative source is here.
