Maple leaves in autumn
A couple of pictures of maple leaves in autumn colours. Unfortunately the leaves are a bit frostbitten, but the colours do still show off pretty well.

A. palmatum 'Seigen'

A. palmatum 'Kiyohime'
An other Kiyohime

Unknown A. palmatum

Atropurpureum

After having discussed this tree with some Swedish bonsaists I think it is a A. palmatum ¨'Katsura'.
