This is a cutting from a cutting from a cutting that's originally from that tree. It's a fast grower and the roots are insane, quickly filling any pot and escaping in all directions. I once had a cutting with a root that went over the rim of a pot, along a concrete path then into another pot.

For this tree I took a year old cutting and planted it onto the top of a stump I had lying around. I didn't bury the stump, I just wrapped it loosely with alfoil and kept it moist, and within a few months the roots had reached the soil level and the tree took off. That was three years ago and the roots continue to wrap around the stump, so I'm assuming it will one day completely envelop it.
Today I defoliated the tree and gave it a tweak with some wire in preparation for summer. Over winter in my back yard they slow down and look a bit pale, but once the warm weather hits they darken and grow strongly.
..and yes, it needs a better proportioned pot.
