really weird when it's young.
It grows slowly, so seeing it in full grandeur is rare possibility. Specimen on the picture grows in Powsin (Poland) in Botanical Garden. I think it is about 30 years old - that's approximate age of the garden.
It stems are long (up to 60 cm) and do not produce side stems. Interesting solitaire tree for really big gardens, otherwise brings too much oddity and chaos to the general impression.
