While I don't necessarily want to have an entirely succulent crown, I do like the idea of having a couple succuelents and lavendar in with my crown. Also we are growing hops at our house this summer, so perhaps we can use some of that as filler.
Your plant ought to be ok if you get any soil mixture prepared for cactus. The jade plant is quite a beautiful plant that's considered by many people to be a sign of great luck. These plants don't have much root system therefore a huge pot isn't required.
