Aesculus "monstrosa"

A totally bonkers plant 

A grafted cultivar of the common horse chestnut, 

Only growing 10-20cm per year 

Almost its entire growth habit forms contorted flat 'fasciated' stems, 

It grows well in larger pots, where I have one plant for the last 5 years which is still only 60cm tall 

Or equally good in a sheltered spot in a garden bed.

3 litre pots 15cm
