I was in Central Park last weekend when I stumbled along this species of Aesculus. I was quite taken with it -- the golden foliage was brilliant and it had a regular, columnar form.
It's not a horsechestnut (Aesculus hippocastanum) and certainly not A. parviflora or A. pavia. From anything I read about A. flava and A. x carnea, it seems the bark is too smooth. I am completely baffled. It could perhaps be A. chinensis or A. indica, though they both seem to be fairly rare, and the description doesn't seem to quite fit. This tree was like a buckeye on the trunk of a tuliptree...
Does anyone know what this is? Please, please tell me!
If not, I suppose I will have to wait until spring and see if the flowers give us any better clues!
