Cool jade. I think I remember seeing this one on another forum (IBC?) while reading about jades and it actually inspired me to buy one of my own. Mine has been relegated to houseplant status until it puts on enough girth to even think about training. Do you have a lot of extending growth that you have to cut back to maintain the shape? Mine seems like it grows like a weed.
In the winter under cheap fluoro lights it grows a bit. In the summer it starts to grow around July but nothing crazy. I think the trunk has hardly thickened in the 7 years I've had it.
