This desert rose doesn't belong to me, belongs to my personal friend who lives in Viet Nam. He has so many good ideas of what to do with his adenium obesum, and this is one of them. He also had one pot growing in water with no soil, and another that he grafted a caudex on top of the branch. I learned many things from him.
He said, when he worked on this plant, he had to hold his hand very still.
