Orostachys japonica - Rock Pine
A Japanese member of the Crassula family. These are incredibly interesting the way the leaves spiral around the stalk. They can range in color from a almost florescent green to yellows, red and orange. Easy to propagate, pups form in cute rings around the main plant. These have such a different look at different times of their life cycle, looks like a totally different plant! Once it flowers that rosette is gone, but it puts out tons of pups before that so you will never be in short supply of these.
Current batch looks like FIRST photos.
