Japanese birch ( bush )

Japanese birch ( bush )
This is an ornamental plant, which has many varieties.This bush has a very beautiful color of leaves by the way he and winter the same.
In our parks they planted a lot of them for the landscape this bush is not a large size of about one meter in height.
It cleans the air well and is resistant to toxic gases just suitable for planting in urban areas.
I want to find somewhere and buy a very beautiful bush in the garden at home.
I would also like to see how it looks in winter, as I have not noticed it in winter in the park.
