I am looking at your photo..yes, your grapto seems to be planted with a Jade succulent. I also try not to mix my jades with any succulent if I can..they also grow quite big as it branches out.
But for this planter, I dare not bother my Jade, seems okay with it pushing against the other noid succulent. But I am learning, so I never repeated this set-up to my other jades.
It used to be this small in 2010:

But you know I keep most of my succulents outdoors, so they grow freely year round. Maybe in your area, it is possible their growth will be tempered a bit since they will stay indoors during winter.
