Hello Paul,
You got a nice colorful collection. Nice to see when fully grown. Did you ever come across a Variegated Finger Jade? Crassula argentea cv. 'Gollum variegata'. I have a regular one and then saw a variegated one. I can't find them for sale any where on the planet. I did get a promise on his waiting list. Maybe in a few years.
