Chris - My dad rooted one and his rooted one outgrew the original. They propagate easily by air layering. He used a wooden box for the soil and removed a ring around the limb and applied rooting powder. He has done at least 7 or 8 of them.
I'd like to get the red tinted one. I think it's called 'Red Majestic'. It doesn't look as twisted but has nice color.
