Size = hard to tell is it currently in a deep pot lying at an angle, I have no idea how deep it is planted as well. I guess maybe 10-15 Cm?
Source = Cutting from a friends tree when he reduced the height.
Cost = Nil
It was an experiment to see how large a cutting I can take and this is one of 2 I took and the only one to survive. I was planted late winter / early spring last year ( 2012) and has been growing and since then.
I will not be able to do very much until I repot this winter to see what I have, so it will be a big surprise then
