Hi Alain,
I'm partial to prunus trees of all kinds. Looks like you have some good stock there. Was the first pic taken after collecting it from the ground? I have peach tree growing in the ground that I'm thinking of collecting next spring.

Yes, it was removed from the ground in February 2005.
The top dried out for lack of care while I was away one summer, but this species doesn't tend to lose branches for unknown reasons as is often the case with other varieties.
The leaves are very big, but they can reduce a little, this species is not so common as bonsai, so I don't have much info about it.
What i like is the texture of the bark, and its colour (it has some bronze tones in some places) and of course, the flowers. I pruned it quite hard last winter, and to my suprise, there were flowers on small branches. So maybe it is possible to make the foliage pads a bit more compact and still see it flower in early spring, before it leafs out.
I will add that root cuttings take very well in late winter : I have one in my garden that will probably become an ornamental tree in a couple of years.
