I lived next door to a guy some years back that had tons of those things. I'm talking like 50+ of them. He made them from cuttings that he used a solution to get them to take root. He had given me one when I moved and I had it for a good while. I liked the tending. It really was calming. I actually thought that was BS before I had to do it.
It now lives with my X wife...I think. She kept it so but I really have no way to know what happened to it. It be a shame to have destroyed it but I"m sure I'm not the only guy to see the lack of logic that walks hand in hand with an X spouse.
