Small japanese maples

All these young plants are from seeds or cheap garden material. Its fun to grow them in pots. They have never ever been in field.  I don´t know the exact varieties...
1. A.p. with "cut" leaves.
2. A.p. with "common" leaves.
3. A.p. atropurpureum with red leaves

 

Autumn 2017

The same plant in autumn 2012

Second one - development spring 2013 - autumn 2017.

Very first picture of A.p. atropurpurpureum from autumn 2013.

Atropurpureum in november 2017 before pruning.

And after pruning and wiring.
