Magic money tree

I am staying at my daughters house this weekend. Lucy and Gary are in Austria on a skiing holiday for a few days so I am giving Caspar some company and a bit of gentle guidance every now and then! And looking after the dog too. This plant was on the table when I arrived. I had no idea there was such a plant as a money tree. I thought the magic money tree was just an insult to be thrown by politicians at each other. Having looked it up, it seems this plant is supposed to bring good luck.
