I think it is more of a vine rose(if there is such a thing?) and has no thorns. It is mostly evergreen but after the cold this year got rid of most of it's leaves maybe it is semi deciduous?
I used the last of what is called Chinese Akadama a couple of years ago as a filler on the less important mixes as I never liked it. That and the Scorio filler in this orchid pot makes me think this was a pretty slack mix from a few years ago, but other trees have done fine in such mixes.
Again there has been more die back on the cut roots than I would expect from normal collected bonsai material. Enough fine roots but but same as the top nothing is dominating yet!
The plan is to get as much growth as possible so I put it in a good old black nursery pot with a fairly gritty mix left over from doing the Willow. After a layer of 10mm Scorio to take up a little space, I used Diatomite akadama zeolite peat moss mix.
I will experiment with some low toxicity fungus sprays over the growing season to keep the mildew away and fertilise well to see how much growth I can get before I start experimenting with how these are affected by pruning.
OMG left the computer for a minute and and 1 year old daughter posted what I had written
At least she didn't delete it 
Better get the pictures up before I lose the post
