The first image is by end of March of this year. So there is seven months between the first and last image. This amazing. Next year by the end of summer this hornbeam will be show ready. The tree was NEVER styled before March of this year. It was collected like this two years ago and left alone since.
It is an oriental hornbeam, Carpinus orientalis. This is the greatest discovery as species usable for bonsai in the past ten years. These trees are hardy in central and northern Europe! Just in case you want one, I have a whole bunch in all sizes.
